Cucumber is a fruit that is not only fresh and nutritious, but also has many beauty effects. In the summer, cucumbers are sold more and more. Cucumbers can be processed into many delicious dishes such as salads, stir-fries, juices, decorative dishes… When shopping for cucumbers, many people have the mentality of choosing straight fruits, instead of curved but real fruits. Is this a good choice? Growers have told 4 great tips when choosing cucumbers, you can refer. The way to choose cucumbers is similar. Look at the color of the cucumber When choosing cucumbers or cucumbers, we can first look at the color of the cucumber. Normal fresh cucumbers should be green and dark green, some people think that the lighter color will be softer, this is not the case. Because mature cucumbers/cucumbers naturally have a lot of sunlight During growth, the color is darker, while cucumbers that are fertilized or stimulant, as well as cucumbers in a greenhouse, the light time is shorter and the color is much lighter than that of naturally mature cucumbers. Therefore, you should choose fruits with a darker green color. Illustration. Look at the straightness of the cucumber When you buy cucumbers, you will usually see curved and straight fruits. Vegetable farmers said that cucumber is a natural vegetable, because it belongs to the family of vines, plus many factors such as light, temperature, fertilizer … so cucumbers will be bent somewhat. With straight fruits can be enlarged with stimulants. Therefore, it is best not to buy a fruit that is too straight, so choose a fruit that is slightly curved. But note also should not choose too curved fruit, curved, round shape, uneven fruit body such as big head and small head, these fruits are often stunted and lack nutrition. Look at the flowers in the cucumber navel When buying cucumbers, if we pay attention, we will see that there are many cucumbers that still have a small flower in the center of the fruit while most of them have no flowers. Many people believe that such fruits with flowers are usually freshly picked, still fresh. In fact, when picking naturally mature cucumbers, the flowers at the navel will fall off naturally after a day, leaving a scar on the top. As for melons with flowers at the navel that look very fresh, big and bright, after picking for many days still not falling, it shows that it is used growth drugs, so it is not recommended to buy such fruits. Look at the thorns of the cucumber When buying cucumbers, we often touch the thorns on the surface of the cucumber with our hands, these thorns can protect the cucumber during growth. If it is a fresh cucumber, the thorns on the surface will Small and dense, when touching with your hand, you will see the spines fall off. However, if the surface of the fruit is relatively smooth, usually the melon is long and not fresh, avoid buying. Once you have selected delicious cucumbers, you can bring them home to process into some of the following delicious dishes: 1. Cucumber Salad Resources: – 2 cucumbers – 1 chili – 1 bulb of garlic – 30ml rice vinegar – 1 teaspoon sugar – 1 teaspoon fish sauce – 1 pinch of cornstarch – 60ml of water Making: – Cucumbers are washed and soaked in salt water for 15 minutes, then rinsed under running water. – Cut off the ends of the melons and then scrape them into thin slices. Peel and mince garlic, minced chili. – You take each slice of melon, roll it into a circle, and place it on a plate so it’s beautiful. – Put fish sauce, sugar, rice vinegar, 60ml water, a little cornstarch, garlic and minced chili into the pot and stir well to dissolve. Turn on the stove to boil the fish sauce mixture, then turn off the stove, let it cool before using, so we get a slightly viscous fish sauce mixture. – When the fish sauce mixture has cooled, sprinkle it evenly on the cucumber plate, so the cucumber salad is complete. In just a few simple steps, you have a delicious, crispy, sweet and sour cucumber salad to enjoy! 2. Cucumber cake Resources: – 140g cucumber puree, 10g cooking oil, 20g fresh milk, 110g low gluten flour, 1 egg, 20g powdered sugar Making: – Cucumbers are washed, cut into small pieces, then put in a blender, puree. Then pour into a large bowl. – Pour milk, cooking oil into the bowl of grated cucumber. Crack the egg in. – Stir everything. Then sift in the low-gluten flour and powdered sugar. The amount of sugar can be customized according to your sweetness level. – Continue to stir the mixture into a liquid, no lumpy powder. – Prepare a non-stick pan, do not put oil in the pan nor turn on the heat. Use a spoon to scoop up some flour, pour it slowly from above, about 15cm from the pan surface. Let the dough spread out naturally into a circle. Then turn on the fire. – There are small holes on the surface of the cake, but that’s because the dough has not frozen. Then, when the bottom of the cake is cooked, turn it over and continue frying. After flipping this side, cook for a little longer, you will see the cake is slightly puffed in the middle, the cake is cooked. The cake has a faint scent of cucumber, very light and pleasant. Cucumber cake is delicious when eaten with ketchup. Good luck!

How do jellyfish form? Ms. Miranda Lowe, curator of the Natural History Museum, in London, England, said the life cycle of most jellyfish species is similar. As hermaphrodites, jellyfish have two gonads, male and female, located in the longitudinal gastric tube symmetrically across the gastric plane. Normally, a jellyfish goes through five stages in its life. First, the adult jellyfish will “lay” eggs and sperm into the water. These two cells combine to form a fertilized egg in water. The fertilized egg develops into a small larva, called a planula. It looks like a microscopic worm and can move freely through the water. The planula will look for a solid surface, such as the seabed, for shelter. During this time, it will develop a digestive system and be able to feed itself. Thanks to the right water and temperature conditions, the planula will turn into a polyp. Polyps sprout, multiplying themselves into large clumps that look like giant bushes. When the right conditions are met, the polyps release into many young jellyfish. After the jellyfish is produced, the polyp changes to a younger polyp form. Young jellyfish continue to grow into adults. Despite their unique beginnings, most jellyfish have a short life span, usually from a few hours to several months. Some species can live for several years. However, the immortal jellyfish (scientific name: Turritopsis Dohrnii) is outside this rule. The secret of “tricking” Death The Immortal Jellyfish is a jellyfish-like waterfowl, of the phylum Cnidaria, commonly found in the Mediterranean Sea or the Sea of ​​Japan. It is shaped like a bell, with a diameter of about 4.5mm. The membrane of this jellyfish is quite thin, except for a little thick at the top. Their stomachs are relatively large, bright red in color. Young jellyfish are 1mm in diameter and have only 8 tentacles evenly spaced along the edge, while adults have 80-90 tentacles. Immortal jellyfish can reverse their life cycle when injured or starving to death. This means they could theoretically last forever. When physically damaged or under stress from starvation, the adult immortal jellyfish will transform the body’s tissues and circulatory system back to a polyp state. Because of the loss of tentacles and the ability to swim, polyps again settle to the sea floor. Over the next 24 – 36 hours, this polyp will develop into a new polyp, located in the early stages of the jellyfish. Then gradually, this polyp will hatch into a jellyfish. This phenomenon is compared to the life cycle of a butterfly. Instead of dying, the butterfly can transform back into a caterpillar and then from the cocoon, it will spread its wings again. The process behind the “rebirth” of the immortal jellyfish is a process of differentiated transformation, which is extremely rare in animals. According to research by scientists, cells in adult jellyfish and cells in polyps are different. The process of adult jellyfish shrinking into polyps allows it to form a new body, different from its original form. But the new adult jellyfish and the old jellyfish are genetically identical. Reversing the life cycle can be repetitive. In perfect habitat conditions, immortal jellyfish will never die of old age. Ms. Miranda commented: ‘We can be too focused on the large jellyfish. But little animals like this can provide a lot of great science about jellyfish and the natural world.” Diagram of the life cycle of a jellyfish. Faint existence Scientists think that the immortal jellyfish likely existed in the oceans long before the dinosaurs went extinct about 66 million years ago. But research on this animal only began in the 1980s. Immortal jellyfish were first discovered by scientists in 1883, but it was not until 100 years later, in 1980, that people accidentally discovered their immortality. University students Christian Sommer and Giorgio Bavestrello collected polyps from immortal jellyfish and watched them until the polyps turned into jellyfish. As immortal jellyfish mature, they assume that they must reproduce before they die. But unlike other species, they quickly turn back into polyps and settle to the bottom of the tank. Through observation, the two students realized that when under stress, this jellyfish would fall to the bottom of the tank and transform without fertilization or becoming a planula. This discovery led scientists to name the jellyfish Turritopsis Dohrnii the immortal jellyfish. However, not always immortal jellyfish can “fool” Death. They are the prey of many other animals such as sharks and turtles. The polyps of the immortal jellyfish are also defenseless against the pursuit of sea slugs or crustaceans. It is difficult to find out how long the immortal jellyfish can live. Immortal jellyfish are very sensitive, so laboratory studies are also fraught with challenges. Despite the difficulties, Mr. Shin Kubota, a Japanese scientist, has been raising immortal jellyfish since the 1990s. He commented that taking care of them is very time-consuming. Every day, he has to monitor the water temperature, the ambient temperature, the salinity of the water. The species’ favorite food is shrimp eggs, which must also be crushed. Kubota’s research shows that, in about two years in captivity, the immortal jellyfish have “rejuvenated” about 10 times. This jellyfish has a relatively secretive lifestyle, so their development is difficult to detect. Small size, translucent color, so immortal jellyfish are hard to see with the naked eye. Another reason the immortal jellyfish’s existence is overshadowed is that their existence does not have a negative impact on the environment. Also, in the treasure of human knowledge, the immortal jellyfish is still a mystery to be discovered in the future.

Characteristics of the tree group that produces fruit at the tip of the branch Lychee belongs to the group of year-round green leafy trees, multi-use trees, both for fruit, shade and landscape. The trees in this group often have the phenomenon of fruiting every year, which means the year of fruiting, the year of no fruit, the year of little fruit, the year of many fruits. Longan and litchi are all fruit-bearing trees, …. That is, the branch from the fall of the previous year is the mother branch bearing fruit next year. If the branch is healthy and the cake is dull next spring, flowers will bloom on the top of the branch. If winter has budded spring leaves do not flower. Therefore, in order for the tree to produce many flowers next spring, it is necessary to prepare many branches from the previous autumn, the branches are old and strong. That depends first of all on the post-harvest care. Longan and litchi trees grow fruit after a year, after harvesting, the branches and leaves fall off, which is the period when the tree is most physically exhausted. From the research results of agricultural experts, after harvesting, the roots are the part that loses the most force, followed by leaves and branches. In order to produce normal fruit next year, folk care experience along with cutting branches, pruning the canopy must be “compensated” or “compensated” in the post-harvest period. The selection of fertilizers and fertilization techniques are very important in order to restore the health of the tree, ensure the recovery, growth and development after 5-6 months of fruiting to continue to produce fruit next season. After harvest, longan and litchi trees need to be cared for and “compensated” so that the next crop can still be productive. Photo: TL. Van Dien fertilizer – The perfect choice for longan and lychee Among the current fertilizers, in addition to organic fertilizers, only Van Dien fused phosphate fertilizer and Van Dien NPK multi-element fertilizer products can meet the above demand for longan and litchi. Easily digestible nutrients in Van Dien fused phosphate fertilizers include: P2O5 15-19%, MgO 15-18%, SiO2 24-32%, CaO 28-34%, and many other micronutrients such as Fe, Mn, Cu, Zn, Bo, Mo…. Multi-factor fertilizer NPK Van Dien 5.10.3 has the content of nutrients such as: N=5%; P2O5=10%; K2O=3%; S=2%; MgO=9%; CaO=15%; SiO2=14%. In addition, there are trace elements such as B, Mn, Zn, Cu, Co… that other fertilizers do not have. Recently, the multi-factor fertilizer products NPK Van Dien 6:12:3 or multi-factor fertilizers NPK Van Dien 10:7:3 are very good fertilizers for fruit trees, especially in the post-harvest stage. . Using Van Dien fused phosphorus products and Van Dien NPK multi-factor fertilizers helps to provide a balanced, complete, multi-, medium-, and micro-nutrients for longan, litchi to restore roots and branches and leaves. Photo: Vandienfmp.vn. Instructions for fertilizing longan and litchi in the post-harvest period This year’s lychee fruit season is very good, so it is necessary to increase efforts to take care of litchi early, while the longan trees bear fruit unevenly, even many trees do not bear fruit, so the care of this year’s longan must be specific to each tree. Non-flowering longan and litchi trees: The longan and litchi trees this year do not flower if this year is not well taken care of, next year will certainly be poor in harvest. To prepare for the fruiting season in 2022, with the trees that do not bear fruit this year, around June and July, corresponding to the annual fruit collection time, still cutting, pruning and weeding as every year. At the same time, apply deep fertilizer with 3-4 kg of composted organic fertilizer and 3-5kg of Van Dien fused phosphate fertilizer, in order to provide phosphorus and secondary and micronutrients, part to prepare and accumulate nutrients. for the next crop, the nutritional compensation for the recent overgrowth of leaves is too strong. The litchi trees, longan trees are bearing fruit: Immediately after collecting the fruit, it is necessary to immediately start weeding for the trees: Prune toothpicks, pests, overhanging branches, branches under the canopy … at the same time, fertilize the trees, hoe around the canopy and then fertilize. The amount of fertilizer for each root is about 5-10kg of composted organic fertilizer, 5-7kg of Van Dien fused phosphate fertilizer and 3-5kg of Van Dien NPK multi-element fertilizer (5:10:3, 10:7:3. ..). Mix well with the soil, spread it in the canal and fill 2/3 of the trenches, grass cabinets, and garbage to keep the stumps warm. If the soil is too dry, it needs to be watered to keep the roots moist. Based on the time of harvest and the health of the tree, it is necessary to affect the summer or autumn buds. The early fruit trees in June, July, after weeding and fertilizing will give summer buds. Fertilizing for the autumn fortune: Locusts are formed on the leaf axils of summer buds (for early-harvesting plants) or grow from the leaf axils of fruit branches with late-autumn plants. This is the fruit branch of the next year’s longan and litchi crop, so it is necessary to pay special attention to adjusting fertilizer so that the harvest ends before November every year. Apply fertilizer to promote autumn buds in September and October after the summer buds have matured (into the leaves), apply 2-3kg of multi-element fertilizer NPK Van Dien 10:7:3 in combination with felling, pruning and removing branches. pass) in the canopy. Apply fertilizer to promote the collection of 2-3kg of multi-element fertilizer NPK Van Dien 10:7:3 in combination with felling and pruning. Photo: Vadfco. Note, only fertilize the autumn buds for trees under 15 years old, showing signs of lack of fertilizer, poor growth (showing yellow-green leaves) or late fruit trees in August, September. The growth pattern of the tree and the yield of the harvested fruit with more or less fertilizer application. If the weather is dry, it must be combined with watering to help the plants recover quickly and develop early autumn buds. When the buds are collected evenly, it is necessary to spray insecticides to ensure that the buds come out evenly and abundantly, the young buds grow well and are strong enough to make fruiting branches next year. Usually on an old fruit branch, there are many new shoots. When the young branches have enough leaves, it is advisable to trim away the weak, weak branches, leaving only the strong, fat huts to keep as the mother branch for the next crop. In the winter months, do not water, fertilize, create all conditions for the tree to “barren”, inhibit the formation and development of winter buds. By applying Van Dien fused phosphate fertilizer and Van Dien NPK multi-factor fertilizer right after fruit collection to create many vigorous autumn branches, combined with inhibiting winter buds, spring when the weather is warm and humid, longan trees , the fabric begins to spring up. Only apply fertilizer to catch flowers for longan and litchi when flower sprouts appear in the axillary leaves of the branches, the amount of application is about 3-5kg of multi-factor fertilizer NPK Van Dien 10:7:3 or 10:10:3, buried. Seal the manure, then water it to stimulate the buds and flowers. Fused phosphate fertilizers and specialized multi-factor NPK fertilizer products for Van Dien at the same time provide a full and balanced supply of essential nutrients for longan and litchi trees, helping them to grow strong and resistant to external conditions. Under unfavorable circumstances, especially during the winter break, litchi trees balance growth with development, creating bountiful fruit seasons.

Along with Dai Tu tea area, from 2005 up to now, Van Dien fused fertilizer and specialized multi-factor NPK fertilizer Van Dien have also been tested and gradually used for industrial crops in the northern mountainous provinces. . Through the process of using, Van Dien fertilizer has been bundled with production, has a brand and trust with people here. Although no additional lime is required, agricultural land is improved, reduced acidity and increased porosity, crops grow better, higher quality and help farmers reduce the amount of fertilizers and pesticides. diseases, protect the ecological environment, and at the same time reduce labor. Hoa Binh sugarcane growers choose Van Dien fertilizer because it helps to increase productivity, reduce pests and diseases and increase the quality of cane sugar. With white sugarcane, the tree is firm, not porous like when fertilizing with a lot of nitrogen, fresh water, not sour. Purple sugarcane color is smooth and dark purple, increasing the sweet and aromatic taste. When applying Van Dien fertilizer, purple sugarcane and white sugarcane all give long internodes, fat plants, blooming tops, bright green leaves, and hard plants. The Central Highlands has more than 1 million hectares planted with coffee, rubber and pepper trees, of which coffee accounts for nearly 70%, Sao rubber 20%, the rest is pepper. The soil is mainly red basalt and gray soil with thick, porous, well-drained cultivation layer, suitable for many crops, especially coffee, pepper and rubber. After liberation (1975), the Central Highlands’ land was strongly exploited, ethnic farmers here invested to intensively cultivate coffee, rubber, and pepper beyond the allowable limit to have the highest output, ten years. The crop grows well at the beginning, but gradually decreases in the following years due to the imbalance of nutrients in the soil. Due to the limited knowledge of gardeners, the massive use of chemical fertilizers leads to a decrease in yield, crop quality, and an increase in costs. From 1990 to 2013, Van Dien Fused Phosphate Company cooperated with scientists from the Central Highlands Agro-Forestry Science and Technology Institute to conduct many experiments to research and use Van Dien fertilizer for coffee plants. Coffee, pepper, rubber in the provinces of Kom Tum, Gia Lai, Dak Lak, Lam Dong… gave outstanding results. On red basalt soil, gray soil, the yield of 1kg of P2O5 in Van Dien fused phosphorus gave a bumper harvest of 31.6 – 33kg of green coffee, an increase of 11.2% compared to the control (other phosphate fertilizers). Especially on gray soil, the yield of 1kg of P2O5 in Van Dien fused phosphate fertilizer reached 31.7kg of green coffee, an increase of over 20% compared to other phosphate fertilizers, with pepper and rubber, Van Dien fused phosphate fertilizer. It also gives an increase in profit compared to other phosphate fertilizers from 8 to 15%. Especially, since 2010, a series of multi-factorial fertilization (DYT) experiments with Van Dien NPK for coffee, pepper and rubber were also carried out on red basalt and gray soils and gave very good results. different from other types of NPK. According to the new concept, clean agricultural production and organic agricultural products are not allowed to excessively use synthetic chemicals such as chemical fertilizers, plant protection drugs, growth stimulants, preservatives, and variable materials. genetic modification… but rather the use of manure, organic fertilizer, natural mineral fertilizer… is a technology to meet the balanced nutritional needs of plants, while maintaining and improving soil fertility, and protecting ecological environment, leaving no toxic residues in agricultural products, creating products of high quality, safe for users and bringing high economic efficiency to producers. Van Dien fertilizer completely meets the requirements of producing clean vegetables, safe vegetables, organic vegetables…: providing nutrients in each period according to the needs of plants. Vegetables and crops are fertilized with NPK multi-factor fertilizer – Van Dieu’s fused fertilizer in combination with nitrogen and potassium in appropriate proportions for each plant; not only bring high productivity, good quality of agricultural products, ensure safety for users; but also increase the resistance to pests, diseases, drought, cold and spill resistance, reduce the use of pesticides, protect the ecological environment. This is also the key to our country’s agricultural production, ensuring that crops grow well, are safe for the soil, products meet quality standards and confidently conquer the market.

The melon garden on the terrace is 50m2 wide, Ms. Vo Thi Ngoc Anh (born 1990, in District 6, Ho Chi Minh City). Her family designed a hanging system that automatically watered and provided nutrients to the plants. Crispy, sweet melons not only serve the needs of the family, but also give them to relatives and friends. Similarly, Mr. and Mrs. Nguyen Cong Bang (SN 1990, in Tan Phu district, Ho Chi Minh City) also made many people fascinated with the melon garden on the terrace. He and his wife take advantage of the terrace of the house with an area of ​​​​70m2 to plant trees. In addition to vegetables, roses, orchids, they spend 30m2 to grow melons. Big melon, juicy fruit and very sweet to eat. Every day, Ms. To Thuy Hoan (50 years old, in Do Son, Hai Phong) also spends a lot of time taking care of her 50m2 garden. In the season, the garden is ripe and red, and the terrace is very beautiful. When the Covid-19 epidemic appeared, taking advantage of her free time, Ms. Hoan asked for land, Styrofoam boxes and bought seeds … started planting. The amount of land moved up was too much, she had to tie a rope to pull it from the first floor to the terrace. She also makes full use of Styrofoam boxes or plastic buckets as a place to sow seeds. With the crates, she does not punch the bottom, but the edge, about 20 cm from the bottom. Then, she punched a hole in the plastic can and put it on the bottom of the barrel. The mouth of the can is towards the edge of the opaque barrel, making the outlet for water, helping the roots to open, and saving soil. This woman also takes advantage of leftover vegetables, tubers, fruits, and shells of tubers and fruits to put them in the bucket, pour soil on top, then water rice … to form a green manure mixture. Mr. Phan Van Liem’s ​​garden (46 years old, in Tan Phu district, Ho Chi Minh City) is impressed by the “terrible” squash. The area of ​​​​the balconies and terraces on the 4th floor is about 60m2, which he makes full use of planting trees. The largest fruit in his garden weighs more than 34 kg. Previously, he planted ornamental plants to decorate the balcony. After that, when participating in online tree planting associations and groups and visiting some friends’ gardens, he decided to buy pots and land to plant to have clean vegetables and tubers to provide for family meals. The garden is full of fruit. He also grew American figs, kale… Mr. Pham Dang Khoa (Lai Chau City) also makes many people admire with a clean vineyard that he planted and fertilized with his own hands. Although the vines are only grown in boxes less than 1m2 wide, the garden is estimated at 2 quintals. In order to have this vineyard on the 3rd floor terrace, he built a few squares of bricks less than 1m2 wide, pouring soil to plant trees. However, to want the grapes to bear fruit, he worked very hard to fertilize chicken manure and potash fertilizers for the vines. Le Phuong (synthetic)

When having a good soil environment for plants, plant care is also very important, mainly fertilizing and pruning. Fertilization, it is necessary to follow the rhythm of the tree’s life. For example, a newly planted tree, its life cycle is the bursts of buds (buds). As for fruit trees, the tree’s life rhythm is: harvesting, creating buds, flowering and raising fruit. The following is the plant care process Dr. Tran Kim Tinh, lecturer at the Faculty of Agriculture and Applied Biology – Can Tho University, introduces it to readers for reference. Plant ground cover grass. Photo: Minh Dam. First, plant ground cover grass. Keep the water in the ditch 50-60 cm above the ground. Sprinkler irrigation (small rays) or permeable irrigation. Post-harvest pruning of fruit trees. The tree is still small, after each bud, needs to be pruned, created a canopy and only produces 3-4 buds in a year. In terms of fertilizer use, organic fertilizers must be applied annually and only when needed to produce sprouts for seedlings. For fruit trees, fertilize when creating buds to use high nitrogen. When the tree is in the stage of growing young fruit, it reduces nitrogen and increases potassium. As fruit trees grow, farmers should further reduce nitrogen and increase potassium. Farmers should fertilize plants with organic fertilizer every year. (In the photo: Compost production at Clean Farm Company). Photo: Minh Dam. Common mistakes in farming Currently, on land crops, there are too many errors in soil preparation for planting and crop care. The prerequisite is to have the right soil physical environment for plant roots to develop. A lot of gardens, the preparation and management of the land is not right. Errors such as soil compaction are very common in all provinces. This leads to vegetable plants not growing evenly, corn not developing roots, orange orchards yellowing leaves, sleeping during the day. The structure of the soil (clump of soil) is not suitable, the lump of soil is too big for the roots to develop. Soil is compacted, reducing permeability. Keep water too high in the orchard. Use soil that is too acidic to grow fruit trees. Converting rice land to grow fruit trees, but there is no way to prepare the land properly. Improper watering. Planting trees buried roots too deep. Too much nitrogen fertilizer and foliar spray have too many growth stimulants, making the canopy unbalanced with the roots, the tree sleeps during the day. The soil structure must be suitable for the plant. Photo: Minh Dam. In farming there are mistakes, which can be easily remedied. For example, over-fertilizing nitrogen, spraying foliar fertilizers, but there are many errors in cultivation, which are difficult to overcome or even impossible to overcome, but must be cut down to replant. For example, in rice farming, farmers are advised to withdraw water mid-season, or to withdraw water several times in a crop. If farmers withdraw water by draining water from the field, this is a very dangerous practice. Because of doing so, the rice soil becomes acidic very quickly. Instead of recommending water withdrawal, it must be recommended to squeeze the water. That means adjusting the amount of watering so that by that point the field becomes dry. For upland crops, soil compaction is very dangerous, because when the soil is compacted, it is very difficult to overcome. The pH must be right One thing to be concerned about, the soil pH in the Mekong Delta is now seriously declining and depleted of potassium. Plants cannot absorb nutrients effectively when the pH is not raised to 6-6.5. Due to the serious decrease in organic matter in rice soil, when flooded, it is not possible to raise the pH. There are still many shortcomings in rice cultivation, when it comes to soil, that need to be studied. Soils in the Mekong Delta are seriously lacking in potassium and need to be supplemented with potassium, especially in the fruiting stage. Photo: Minh Dam. It is not enough, soil pH must be suitable and nutrients for plants must be sufficient in quantity and type. It has been shown in science that the mineral nutrients for plants must be sufficient in type (14 types) and in quantity, if one of the 14 types is lacking, the crop yield will decrease, even though 13 types The rest are high. In order for plants to absorb nutrients well, the pH of the soil must be suitable, preferably 6-6.5. Below pH 6, absorption of some nutrients is difficult and when the pH drops to 4-5, nutrient absorption is severely reduced. No plants grow normally under low pH and high pH conditions. For example, the pineapple tree can grow on acidic soil, but it is not normal. For sustainable farming, the following criteria should be considered and trained for farmers: Technical level of farmers, organic content in soil, soil pH in profile, soil texture, soil structure in analysis. area, irrigation capacity, drainage, fertilizer application process. Currently, there are still many issues that need to be studied to determine the soil properties that need to be addressed. The ecological characteristics need to be analyzed thoroughly, for ecological zoning. Minh Dam – Ngoc Thang ( write the)

“Growing trees on the terrace is not simple, requires the grower to have patience and hard work. Fortunately, I am a farmer’s son. Since the age of 10, I have been gardening and farming, so I know quite a lot. knowledge of cultivation”, Ms. Nga shared. When starting to plant trees on the terrace, Ms. Nga had to tinker with the planting method herself. Previously, she saw a friend planting trees, often using bananas buried in the ground for good plants, because bananas contain a lot of potassium. At that time, she thought why not grind bananas, mix with eggs, incubate flowers and then fertilize the plants. “I have been successful with the organic method of growing plants, using “waste” as manure. Now, no tree can make it difficult for me”, Ms. Nga shared. Thanks to the application of the above method, now, Ms. Nga’s orchard is green all year round, and the fruit is sometimes hanging on the branches. In addition to using eggs, milk, bananas, soybeans, etc. to make compost, she also uses fish protein, rice bran, cow manure mixed with soapy solution, composting for plants, helping plants avoid pests. bug. Ms. Nga also uses micro-organisms, tricodema, smoked rice husks, peanut shells, and oil cakes for growing plants. For fertilizing, it must depend on each type of tree, each stage is suitable, so that the fruit tree is always full of branches. On the terrace, Ms. Nga has been growing red flesh dragon fruit for more than a year. The tree has now begun to flower. The guava tree is laden with branches thanks to the organic fertilizer made by Ms. Nga. Ripe fruit is crunchy and sweet. Since her two children went to study abroad, there are only husband and wife in the house, so for the most part, Ms. Nga grows many fruit trees. The fruit tree is laden with branches. Ms. Nga said that not everyone succeeds in planting trees on the terrace. For her, in addition to using the right planting method, she also has to have a real love for trees. Every day, when she is free, she goes to the terrace to monitor and pay attention to every corner of the tree to see if they are attacked by worms or aphids. On the days when she went home to sell goods, it was 12 o’clock at night, she still went to the garden to visit each tree and check each leaf. Nga and her husband like to eat twisted Kale, moringa, and Korean radish, so they always grow them in the garden. At the end of this litter, she nursed her own trees to replace the old litter. Juicy melon. Kale has been planted by Ms. Nga for more than two years, the tree is always fat, the leaves are green. American fig tree. Nga shared, all the trees in the terrace garden, after harvesting, will be pruned and removed all the old leaves so that the tree can grow new branches. Recently, Ms. Nga often shares photos of her garden and planting techniques on online associations and groups. Many people come to ask for the secret, Ms. Nga is always enthusiastic to guide.

Christian Sommer is an extremely hardworking student, so even while on vacation with his girlfriend, this guy doesn’t neglect his studies. For his studies, he dived into the azure waters under the cliffs of Portofino to learn about the marine life here and found a small jellyfish – Turritopsis nutricula (lighthouse jellyfish). This jellyfish is only four to five mm in size, the whole body is transparent, in the middle of their body is a red digestive system like a lamp, so it is called a lighthouse jellyfish. Although lighthouse jellyfish have a very beautiful appearance, due to their small size, people often do not see or notice them. Immediately after observing and discovering, Sommer collected them in a thin mesh bag and placed them in a container of seawater in the hope of bringing them to the refrigerator and turning them into specimens. But that day was a weekend, on the beach there were many interesting games and because of a bit of playing, Christian Sommer forgot to put them in the refrigerator as originally planned. It was not until the next day that Christian Sommer remembered what he had forgotten. When he found the barrel, he took it out to look, but when he looked closely many times, Sommer found nothing inside the net bag but sea water. So what happened? Even though lighthouse jellyfish are so small they can still be seen with the naked eye, why do they completely disappear in just one? Still not believing his eyes, Sommer checked the container a few more times, this time even more surprised, at the bottom of the container there were many tiny things, almost invisible. can see. After many observations and analysis, Sommer realized that these were exactly the polyps of lighthouse jellyfish. Why did Sommer feel so surprised? In fact, lighthouse jellyfish are a species of hydrophyte, and they have two different developmental stages in their life cycle: a polyp (hydroid) stage and a jellyfish development stage. Adult jellyfish will lay eggs and are fertilized in water, after which they retain the fertilized eggs in the female jellyfish until they develop into planula larvae. These planula larvae can swim freely like worms or float under the sea and then sink to the sea floor to form digestive systems and reproduce asexually into polyps; After asexual reproduction is budding, the polyps slowly develop into adult jellyfish and begin a new life cycle. Usually a jellyfish life cycle lasts a few weeks to several months, and they die after laying eggs. But now, the fact that these jellyfish lay eggs, fertilize, become larvae, mature and then turn into polyps within a few days is what makes Sommer extremely surprised. This means that these jellyfish have not disappeared, instead they are rejuvenated like a full-blown rejuvenation. Further research has found that not all lighthouse jellyfish will rejuvenate, their life cycle will still proceed normally. However, when faced with certain adverse conditions such as food scarcity, water temperature changes, sea water decrease in salinity or physical damage and many other adversities, they will fend for themselves. rejuvenate, turn into polyps and begin their life cycle once more. Theoretically, lighthouse jellyfish can reverse its life cycle continuously without limit of times, so it can be said that lighthouse jellyfish is an immortal life form and is also the only species in the world that can such a mechanism of life. Moreover, each time this rejuvenation process is performed, the lighthouse jellyfish can separate into hundreds of different polyps, which means that the current lighthouse jellyfish have “aged” very much. , may even exceed several thousand years old. Therefore, this species is also considered the longest living organism on the planet, if not completely immortal. It is widely believed that lighthouse jellyfish appeared during the Cretaceous period, and if so, lighthouse jellyfish in the ocean have lived for more than 100 million years. The lighthouse jellyfish is actually an invasive species, it originated in the Pacific Ocean and is thought to colonize oceans around the world through ballast water. Due to its small size, and not causing too many adverse reactions to the ecosystem, few people notice its invasiveness.

In any season of the year, the rose garden on Ms. Hien’s terrace blooms brilliantly. Can’t believe I can grow a beautiful flower garden In the afternoon, the sun went out, Dinh Thi Dieu Hien (living in District 11, Ho Chi Minh City) went up to the terrace again, immersed in the blooming rose garden, emitting a sweet scent. She said, up to now, she does not believe that she can grow such a beautiful rose garden. Because, the rose is a species suitable for temperate climate while HCMC is hot all year round. Hien said, she grows flowers because she loves and wants to beautify her house. So, when she saw that the balconies of many houses abroad were covered with roses, she dreamed of being able to grow this flower on her balcony. The flower garden has many different types of domestic and imported roses. That passion burned even more when she noticed that there was a movement to grow infrared flowers in Vietnam. Unable to wait any longer, she ordered a pot of roses from Phu Tho province to plant on the balcony of the house. “Red is very red. Must understand to take care of flowers. At first, I only planted persimmons in the balconies. However, here the tree does not have enough sunlight, so it is very weak, giving small, few flowers. So I put the flowers on the terrace for the plants to have enough sun and then brought the plants back to the old location, “said Hien. To plant such a beautiful flower garden on the terrace, Hien spent 3 years tinkering and experimenting. Moving the trees constantly made her tired and came up with the idea to turn the empty terrace into a flower garden to grow roses. However, when moving the tree to the terrace, she had to face the reality of hot weather, burning hot sun. In order for the plant to grow well, for beautiful flowers, she tinkered and found her own flower care formula. She said: “In the balcony with little sun, every day I just spray the leaves thoroughly in the morning. If it’s too hot, in the afternoon I just mist the leaves and spray before 5pm. The fertilizing regime also reduces high-protein fertilizers because less sunlight and more protein are easy to cause diseases. In the early years, she fell under stress because the flower growing failed continuously. “When planted on the terrace, the tree will get more sun and wind. Therefore, I watered twice a day, sprayed the leaves thoroughly in the morning and afternoon. In addition, I also pay attention to shading the pot with straw, pine bark … or growing vegetables and short-rooted flowers that both provide oxygen and cool the pink roots,” she added. Insomnia, awake because of flowers She said, in order to accumulate that experience, she spent sleepless nights just thinking and trying to make the garden live and bloom beautifully. In the first year of planting flowers, Hien almost always fell into a state of stress, stress by investing effort and money, but the tree did not sprout, give buds, bloom. Up to now, she has found her own secret to being able to grow all kinds of roses on the terrace of her house. Not giving up, she joined and learned from rose-growing associations and groups. She applies that technique to her flower garden and then spends time researching and gaining more experience from the fact that she takes care of flowers every day in the garden. Finally, after 3 years, she understood and grasped the characteristics of roses. Even, she has accumulated experience and techniques for growing roses on the terrace in the year-round hot weather of Ho Chi Minh City. After 3 years, she has covered her empty terrace with many kinds of roses for bright, fragrant flowers. She shared: “Hong loves the sun, in addition to the need for 3 hours of sunshine or more, it also needs the following factors: first soil, second pot, three varieties. Fertilizer is just the last addition. My soil composition consists of: 25% finely ground alluvial soil, 45% vermicompost, treated coir, smoked rice husks, bat manure and perlite. She also noted that the mixing of the soil must ensure that the soil is loose and well-drained. Because persimmons must be planted in pots, placed on the terrace, the pots also have certain criteria. Ms. Hien’s experience is that it is necessary to choose a good drainage pot, even after buying it, she also drills more drainage holes. To maintain the flower garden, Ms. Hien spends a lot of effort and time taking care of it with her own techniques. In addition, Ms. Hien also listed techniques for fertilizing plants. She always spends a weekend to fertilize and spray her flower garden. Up to now, Ms. Hien has in hand the technique of fertilizing roses according to a specific formula and experience. One of the factors for the tree to flower wrongly and continuously is the pruning technique. These techniques include: choosing a fertilizer that provides adequate nutrition for each stage of the plant, when fertilizing, it must be applied 2-5cm from the wall of the pot, 3 days before the flowers die, apply fertilizer to provide a lot of phosphorus to stimulate the roots. For the next sprout, after cutting the flowers, fertilizing provides a lot of nitrogen, applying oil cake in combination with watering the roots with seaweed… Especially, she grows flowers without using drugs and chemical fertilizers, but only using natural products. In particular, Ms. Hien grows completely organic roses and does not use any drugs or chemical fertilizers. When it comes to dealing with pests, she only uses neem oil, orange essential oil, etc. Therefore, her flower garden is extremely safe for family members. Even now, even though she is pregnant and nearing her due date, she still goes to the terrace, goes to the rose garden to see flowers, and takes care of the plants every day. So the flower garden is not only beautiful but also very safe. Hien’s family members are very fond of flower gardens. Currently, the flower garden on the terrace of Ms. Hien has many varieties of Vietnamese roses such as: Sapa ancient roses, Hai Phong ancient roses. There are also many beautiful and attractive infrared flowers such as: Soeur Emmanuelle, Juliet, Mac Spice, Angela, Masora, Mon Coeur, Friendship of Strangers, Purple Ice Cream, Corail Gelee, Katherine Blue, Amandine Chanel , Pope John Paul II, Double Delight… Even though she is pregnant, Hien can still go to the flower garden to look at the flowers and inhale the sweet fragrance of the roses. Ms. Hien further shared that, in order for roses to have beautiful and regular flowers, tree pruning occupies an extremely important position in the care process. For each type of persimmon, she has a specific way of pruning branches. In addition to roses, Hien is currently growing some fresh vegetables and fruits to add to her menu every day. She shared: “When the persimmon lines are cut, keep watching from the flower to 5-6 axillary leaves, choose the axillary with the most beautiful sprout eye to cut. The bush line should be cut 2-3 axillary leaves, inflorescence line, cut below 4-5 leaf axils. “Cut off all the bad branches, the tree is easy to give root sprouts with long bunches of flowers. If you want the tree to bloom at the same time, when you cut the dead flowers, you should cut them only once, if the flowers bloom before they fade, just leave them on the tree and wait for them to bloom. After finishing, cut it,” added Hien. Posts: Nguyen Son Image: Characters provided

Notably, despite the expensive price, items such as instant noodles with 100,000 VND/pack, millions of fish sauce bottles, and instant pepper cost up to tens of millions of VND per kilogram… are still expensive at home and abroad. Pepper is fertilized with self-composted organic fertilizer from eggs, milk, crab and moringa leaves Eating pepper like candy costs 22 million VND/kg While the price of dried pepper sold on the market today only fluctuates around 65,000-70,000 VND/kg, pepper products with Bau May brand have the lowest selling price of 1-2 million VND/kg. There are even seedless pepper products with prices up to 22 million VND/kg. Why is this product so expensive? Mr. Lam Ngoc Nham, Chairman of the Board of Directors of Bau May Agriculture, Trade and Tourism Joint Stock Company (Ba Ria-Vung Tau), said: Instead of pepper being sold as a common spice, his company has produce premium pepper products that can be eaten directly. This means that this product can be used as a functional food with good health and high economic value. Not stopping there, Mr. Nham has created many direct consumption products that bring great export value, such as milk pepper that can be used for children from two years old or more than 2 million VND/day. kg. In particular, the crunchy dry seedless pepper that can be eaten like candy or fruit costs up to 22 million VND/kg, which is favored by fastidious markets such as Japan, France, Dubai, and Australia. “My company’s Tieu Bau May is fertilized with self-composted organic fertilizer from eggs, milk, crab and moringa leaves. These are all foods with many nutrients that are good for human health. When pepper plants are “eaten well”, they will produce delicious, aromatic peppers and many good nutrients for humans”, Mr. Nham shared. Thanks to this special “fertilizer” created by Mr. Nham himself, it helps to improve the pepper content. Accordingly, the percentage of kernels is absent, the percentage of rice is increased, the shell is thicker and especially, a unique seedless pepper variety is created. In addition, to meet strict export standards, Nham said that the company’s pepper growing areas all meet GlobalG.AP standards, an ISO certified food safety management system. Another special thing is that Bau May Company consumes products with stable prices 3-5 times higher than the market price. For example, at present, the average pepper price is at 65,000-70,000 VND/kg, sometimes the price drops below 50,000 VND/kg, causing many local farmers to cut pepper to grow other agricultural products. However, Bau May is still buying pepper from farmers for more than 150,000 VND/kg. “I provide seeds and technical guidance to each farmer household, convincing them to comply with the organic standards that I set to obtain quality products,” said Mr. Nham. Pepper, fish sauce … super expensive produced by Vietnamese enterprises. Photo: P.MINH – Q.HUY Mantis shrimp fish sauce is as luxurious as wine Living in the sea of ​​Phan Thiet (Binh Thuan), once enjoying the quintessence of fish sauce in a craft village, Mr. Bui Duc Hao, owner of Sen fish sauce company, always cherishes the idea of ​​raising Vietnamese fish sauce to a higher level. . “Although traditional fish sauce is being fiercely competed by industrial fish sauce, there are still many people who want to find delicious bottles of fish sauce with bold Vietnamese taste for family meals. In fact, good fish sauce is very rare on the market, it only stops at craft villages for the people who make fish sauce to enjoy “- Mr. Hao shared. Once Mr. Hao talked and shared the story of fish sauce with a friend who is a culinary expert, the two shared the same opinion that they must preserve the unique beauty of traditional fish sauce. Therefore, Mr. Hao decided to create a delicious fish sauce and of course not cheap. “If making popular fish sauce will easily drown with other brands, not to mention traditional fish sauce is being fiercely competitive with industrial fish sauce,” said Mr. Hao. As an architect, once designed for the rich, the owner of Sen fish sauce knows that in the market there are many people with money and they are willing to spend tens to hundreds of millions of dong for delicious and expensive food. Therefore, he decided to make a high-class fish sauce aimed at the segment of people with money. However, unlike the usual way of making fish sauce, Mr. Hao and his friend do not use fish to make fish sauce, but use mantis shrimp ingredients. Choosing mantis shrimp as a fish sauce ingredient is also a feat. Mantis shrimp only buy the kind that is caught in the spring, because this is the season that according to fishermen, seafood is delicious. Mantis shrimp are selected according to a standard size, not big ones, small ones and must be alive. After that, these shrimp are brought to Tam Giang lagoon to raise fat and reduce salinity. When the shrimp reaches the required standard, it is brought to make fish sauce according to its own recipe. The salt to marinate chuop to make fish sauce must be Sa Huynh salt. Super expensive fish sauce produced by Vietnamese enterprises. Photo: P.MINH – Q.HUY “Fish sauce made from mantis shrimp does not have a high protein content like fish, but it produces a round, aromatic and sweet fish sauce,” said Mr. Hao. Delicious and unique fish sauce needs to go hand in hand with the design. Mr. Hao was originally not interested in fish sauce bottles in plastic bottles because, according to him, doing so “only lowers the value of Vietnam’s famous sauce”. Under the professional eyes of the architect, Mr. Hao decided to change the shape of the fish sauce bottle. It must be luxurious and sophisticated to attract customers at first sight. The exterior is designed as luxuriously as Western wine bottles, inside which he thoughtfully comes with a pouring spout like in high-class restaurants used to pour wine. Mr. Hao is selling a bottle of fish sauce for 2 million VND. Putting this number next to the usual bottles of fish sauce is a difference in price difference. “Many people spend tens of millions of dong to buy a bottle of wine and drink it all at the party, but the bottle of fish sauce can be used for a whole year” – Mr. Hao explains why the company’s fish sauce is so expensive. Another interesting thing, when users feel good, they tend to return to buy regularly, so the company can’t keep up with orders. “This is not only about winning the business problem, but it is important that traditional fish sauce is still in the minds of many people if they know how to do it and meet the right needs,” said Mr. Hao. Unique snack, honey thing Mr. Nguyen Duc Thanh, General Director of Tanimex Long An Company, said that many cashew processing companies have gradually invested in deep processing product lines instead of exporting raw products as before. Deeply processed products with high added value such as salted roasted cashews, snack cashews, honey cashews, wasabi cashews… have been sold in the domestic market and exported more and more. In particular, these products are increasingly popular in the markets of Thailand, Hong Kong and the Middle East. Not only that, Vietnamese companies have the ability to create safe, clean and unique products. In particular, some companies grow cashews organically, so they can expand both domestic and international markets and reach a group of customers with money and high income. Super expensive pepper produced by Vietnamese enterprises. Photo: P.MINH – Q.HUY The demand for luxury goods will continue to increase sharply Despite the COVID-19 pandemic, the purchasing power of the middle and wealthy classes in Vietnam is still quite high, especially for valuable and branded items. The proof is that more and more famous brands are present in Vietnam. Market research firm Statista said that despite the pandemic, the revenue of the luxury goods market in Vietnam is expected to reach 1.14 billion USD in 2021. In general, in the period of 2021-2025, the Vietnamese luxury goods market South will grow by an average of 7.2%. Many experts predict that the consumption of luxury goods will increase sharply in the coming years, including food and technology. It is inevitable when the income of many people increases. Grasping this trend, many Vietnamese companies have launched many high-quality high-end products in the domestic market.

Orange Can be grown in many places, but because the bran root system absorbs nutrients, it mainly grows on topsoil from a depth of 50cm or more, prefers loose, aerated soil but must ensure enough nutrition and good moisture. stable, so only some regions with specific conditions can effectively cultivate oranges. According to scientific calculations, an average of one ton of oranges is removed from the soil: 1.7kg N; 0.5kg P205; 3.2kg K and secondary and trace substances. The soil suitable for growing oranges has a thick, porous, well-drained cultivation layer, with alkaline pH from: 5.5 – 6.5. When the soil acidity is lower than 5.5, the roots will be toxic by Fe, Al, the plants are susceptible to lack of nutritional factors such as: Ca, Mg, P and Mo, the activity of soil microorganisms is also affected. reduced low. The nutrition trace elements such as Zn, Cu, Mn, Fe, B0, M0, C0…. Micronutrients also have the effect of improving the soil, helping to reduce the number of seeds, increase the flavor, beautify the fruit, contribute to increasing the yield and quality of oranges when harvested. Lack of trace elements makes the plant imbalanced in nutrition, prone to yellow mosaic disease, flower drop, young fruit drop, diseased plants and abnormal growth. Due to the above requirements for soil, nutrients and tree characteristics, many concentrated orange growing areas have chosen to use it Van Dien fertilizer n and gives very high efficiency. Lan Van Dien has a fairly high ratio of Calcium, Magnesium, and Silicon, so it has the effect of reducing acidity, gradually raising the pH of the soil, suitable for orange trees. The land for growing oranges is mainly grown on hills, gardens, and riverbanks where it is high and steep; easily washed out and lack of intermediate and trace substances. Lan Van Dien is a slow soluble phosphorus, only soluble in weak acid solutions secreted by the roots, where the plant needs to dissolve the fertilizer, so it is limited to being washed away. Besides Lan Van Dien It also adds essential nutrients and trace elements for plants. Produced from Van Dien fused phosphate fertilizer, specialized NPK multi-element fertilizers for oranges are different from some common NPK fertilizers, in addition to nitrogen, phosphorus, and potassium, there are also medium and micronutrients. Van Dien NPK provides 16 essential nutrients for plants with a high and balanced nutrient ratio NPK Van Dien provide enough 16 essential nutrients for plants with a high and balanced nutrient ratio. For oranges in the business period, the amount of fertilizer invested depends on the quality of the soil in the region, the age of the tree and the annual yield. In 1 year, in combination with rotten organic fertilizer, Van Dien fertilizer is divided into 4 fertilization periods: 1st: After harvesting the fruit. Apply a root of 10-15kg of organic fertilizer, 3-5kg of Van Dien phosphorus. Three times after applying with multi-factor fertilizer NPK Van Dien: 13;3:13 or 12-8-12, 12-12-17. Phase 2: Around March-April, after the physiological fruit drop. Oranges from 4 to 7 years old, apply a 1-1.5kg root; oranges from 8 – 11 years old, apply a 1.5 – 2kg root; Oranges over 11 years old, apply a root of 2.5 – 3kg. 3rd round: In June-July, fertilize fruit after stabilizing the number of fruits on the tree. Oranges from 4 – 7 years old, apply a root of 1.5 – 2kg; oranges from 8 – 11 years old, apply a root 1.5 – 2kg; Oranges over 11 years old, apply a root of 2.5 – 3kg. Phase 4: In September-October, 1 – 1.5 months before harvest, apply multi-factor fertilizer NPK 12:12:17 to limit the second physiological fruit drop and limit fruit cracking, especially weight gain. yield and fruit quality at harvest. Oranges from 4 to 7 years old fertilize a root 2 – 2.5kg; oranges from 8 – 11 years old, apply a root of 2.5 – 3kg; Oranges over 11 years old fertilize a root of 3.5 – 4kg. Van Dien fertilizer provides a full balance of all kinds of macronutrients, intermediate and micronutrients to satisfy the nutritional needs of orange trees throughout the crop year. Van Dien fertilizer helps orange trees grow healthy, balanced, green leaves, bright, thick leaves, less pests, high fruiting rate, large, uniform fruits, reduce fruit drop, help balls, Large, smooth, especially when ripe, the dark yellow skin is very attractive, high yield, increased sweetness, stronger flavor and longer shelf life. How to fertilize: * If, after harvesting the fruits of the previous crop, the incision was made and then fused with phosphate fertilizers and rotted organic fertilizers were applied, now apply fertilizer according to the old canal: spread fertilizer along the canal and then cover with soil, leaves cover the manure. * Can spread fertilizer according to the projection of the canopy back, about 50-60cm from the root, spread the fertilizer and then cover with soil, if it is dry, it must be watered; You can soak the manure to dissolve it and then mix it with water to irrigate.

The woman holds the Guinness world record for childbirth On the official website of the Guinness World Records, Valentina Vassilyev is named the “most blessed” woman in the world with a large number of children she has never been able to surpass – 69 children after 27 times. pregnant. Two children, after being born, could not save their lives. The remaining 67 children were healthy and developed normally. According to the Metafloss, Feodor Vassilyev was a Russian farmer living in the 1700s. Her husband, Feodor Vassilyev, lives in Shuya, Russia. Valentina is his first wife. In the magazine Saint-Petersburg Panorama , in 1834, the author Bashutsky Alexander, mentioned the notes of the Nikolskiy monastery to the authorities in Moscow. Nikolskiy Monastery is responsible for recording information about births and reporting the situation as a way of keeping track of the population. According to records, in 1782, the monastery reported that Mr. Feodor – a 75-year-old farmer – had a total of 87 children with two wives. By the time of the record, 82 children are still living healthy. The phenomenon of childbirth of the Vassilyev family is controversial. Artwork: Getty Images. However, a lot of people are skeptical of this event. According to the History Daily The labor burden is the first thing that makes it hard for them to believe that a woman spends most of her time giving birth, especially in the Russian rural context centuries ago. Not to mention, ensuring physical conditions, eating and drinking activities for children is not necessarily possible. Also, the older a woman gets, the lower a woman’s chance of conceiving. Most women do not become pregnant by the time they turn 40. The rate of conception per cycle for a 45 year old woman is about 1% per month. Valerie Baker, Associate Professor of Obstetrics and Gynecology, Stanford University School of Medicine, USA, said: “Pregnancy is the most difficult physical thing that every woman has to experience. Childbirth is a portal, each pregnancy is a dangerous time to the mother’s life. It entails many risks, dangerous complications such as hemorrhage, premature birth. With twins and triplets, this risk increases ”. Birth 3 and 4 are considered special because the rate of occurrence is not much. Artwork: USA Today. Find the truth The story of Valentina Vassilyev quickly attracted the curiosity of researchers. Many people are determined to find the truth. According to the History Dialy, New Zealander Marie M. Clay discovered a number of articles published in the 1800s about a woman giving birth to 69 children. They are gathered in the book Quadruplets and Higher Multiple Births , published in 1989. Marie admits the story of Vassilyev has many variations. However, historians all believe that much of what is recorded is true and that this mother gave birth to an unprecedented number of children. But the exact number of children Valentina has is remains a mystery. Journal Gentleman (in London, England), no. 753, p. 53, published in 1783, records of a letter about the Vassilyev family. The content of the letter mentioned that the large number of children in this family may come from the husband’s fullness. The writer confirmed this is true, verified by a British businessman, once traveling to St.Peterburg and learned that the Vassilyev family will meet the Queen of Russia. 1878, in the magazine The Lancet , The French Academy conducted the study, overturning the above event. They try to verify whether the large Vassilyev family is real. A member of the Royal Academy of St. Petersburg said this does not require re-verification because the Vassilyevs, living in Moscow, have received many favors from the government. Besides, it is reported that Ms. Valentina lived to be 76 years old. New Zealander Marie M. Clay and her book Quadruplets and Higher Multiple Births, published in 1989. Photo: Amazon. An average pregnancy takes 40 weeks. The more pregnant a woman has at the same time, the sooner she will go into labor. Based on the number of 69 children that the documents recorded, many scientists hypothesize that mothers in Russia must undergo a total of 27 births. Of these, 16 were twins, 7 triplets and 4 quadrants, between 1725 and 1765. Thus, 16 twins of Mrs. Valentina took 37 weeks, 7 triplets pregnant 32 week and 4 times of 30-week pregnancy. The total number of weeks for the 27 pregnancies was 936 weeks. Each year, for 52 weeks, Valentina takes 18 years to become pregnant. In theory, this is quite possible. Twins and triplets, birthing 4 can happen in two ways: Multiple eggs are ovulating at the same time successfully fertilized or a fertilized egg splits into several viable embryos, resulting in identical twins. each other, have the same genetic code. However, these cases are very rare in the world. Therefore, the fact that Valentina has had 16 twins is unbelievable, making this story still a controversial mystery.
