Pham Trung Kien and his wife took a photo with a small guava tree with many fruits. The terrace is just over 7m2, but he still makes use of it to grow vegetables and fruit trees. In order for the garden to grow many different types of trees, Mr. Kien designed a climbing platform and then used foam boxes, plastic tanks … to plant trees. In the photo is a gourd frame with fruit. Mr. Kien said that the most difficult thing about planting trees on the terrace is to transport the soil. Moreover, houses are close to each other, so he has to go to the coastal areas or to neighboring provinces to get land. After that, he composted the soil with ash, rice husks, coco coir together with vermi-compost, cow and chicken manure, etc., and put it in a barrel to plant trees. According to Mr. Kien, planting trees on the terrace or on the ground, plant nutrition is the most important thing. In order for the tree to develop well, produce lots of fruit and be delicious, in addition to using organic fertilizers, he also uses skin and fish bones to fertilize the tree. Mr. Kien uses the head, skin, bones … of the squash fish because this fish often has less odor, fishy, ​​to fertilize the plants. Mr. Kien also came up with a way to mix the soil according to his own recipe. Accordingly, he mixed 50-60% of soil and meat with organic fertilizer. “The soil mixed with the organic fertilizer will be mixed with the fish again according to the ratio: 1 layer of soil, 1 layer of skin, bones, fish head. We do that 2-3 layers, then planting any tree is fine”, he to speak. The secret of this man when planting plants on the terrace is to plant seedlings in small pots first. When the plant begins to grow, he will switch the plant to a large pot so that it can easily absorb nutrients from the soil. Then, every day, he watered the tree 2 times. When the plants flower, every 10-20 days, he will add 2-4 tablespoons of bat manure and manure for fruit trees. Mr. Kien also cut off small, bad branches to create conditions for the plump branches to grow. As for guava trees, he often pruned the branches, not to let the branches get too high, each branch cut 2-4 pairs of leaves … so that the tree focused on raising flowers and fruit. Thanks to this secret, whatever he grows, he has a phylum fruit. “There is no entertainment as cheap as planting trees around the house. It feels great to plant, take care of the trees by yourself, and get your own results. It’s more fun when the fruits you grow are not using chemicals.” , Mr. Kien shared. The apples are juicy, crispy and sweet. Knowing that Mr. Kien planted trees on the terrace with good yield, many people came to visit and learn from experience. Whoever comes, he is also willing to share his secret, just where to buy seeds. He also wrote his own recipe for each plant, how to compost, mix soil for everyone. In addition to fruit trees, he also planted sprouts. This vegetable, he and his wife use it to make salads, eat raw … Mr. Kien said that since there was a garden, he always found his life more meaningful. When he is tired at work, he goes to the rooftop to see the branches, exhausted, and tired as disappearing.

The locality at the forefront of the movement towards high-tech agriculture in Binh Dinh is the midland district of Hoai An. According to Mr. Vo Duy Tin, Deputy Head of the Department of Agriculture and Rural Development of Hoai An District, there are 22 agricultural cooperatives in the district, of which 16 have transformed and operated under the Law on Cooperatives in 2012 and 6 specialized cooperatives. New agriculture is established in 2020. La’sfarm High-Tech Cooperative is one of the first units in Binh Dinh to apply high-tech vegetable production. Photo: Vu Dinh Thung. Since 2019, An Tin Agriculture Cooperative (Hoai An District) has pioneered clean rice production. The cooperative was the first unit of Binh Dinh to grow high-quality rice in an organic way. According to Mr. Bui Long Xuan, Director of An Tin Agricultural Cooperative, in the winter-spring crop 2020-2021, the cooperative produces 2.5 hectares of high-quality rice following the process of no chemical fertilizers, no pesticides, and only using organic fertilizers and microbiological fertilizers to create clean rice products. Currently, the cooperative’s organic rice has been certified, has its own packaging and labels. Initially, the cooperative sold organic rice at the price of 20,000 VND / kg and was well received by the provincial market. “In the coming summer-autumn crop of 2021, we will multiply the area of ​​high-quality organic rice production to improve our ability to meet the market, and at the same time, invest in the application of rice seeding technology and rice drying technology. improve the quality of clean rice products ”, shared Mr. Bui Long Xuan. La’sfarm High-Tech Agriculture Cooperative (Hoai An District) is also the first unit of Binh Dinh province to apply high technology to the production of vegetables and fruits. According to Mr. Tran Bao Diep, Director of La’sfarm High-Tech Cooperative, the cooperative is applying Israeli high-tech techniques such as growing vegetables in a greenhouse, automatic drip irrigation with timer and production control on the phone. smart, fertilize with microbiological fertilizers to create organic products according to VietGAP standards. “The application of high technology in production helps to create clean agricultural products, especially melon with beautiful designs, all sizes and delicious quality, very popular with the market”, Mr. Diep said. The fragrant cucumber by the Institute of Agricultural Science and Technology of the South Central Coast is planted with high technology. Photo: Vu Dinh Thung. Not only developing clean agricultural production models, Hoai An district also develops many linkage models from production to consumption of clean agricultural products locally. For example, the Agriculture Cooperative 19/4 in An Tuong Tay commune specializes in growing green grapefruit in the direction of VietGAP. The initial capital was 5 hectares of green skin pomelo in the garden of Mr. Nguyen Hoai Thuong (Cooperative Director), then the cooperative linked with many other members to increase the total area of ​​green skin pomelo of the cooperative to 55 hectares. Currently, 55 hectares of the cooperative’s green skin pomelo in the business period, each year can supply the market with hundreds of tons of fruit. According to Mr. Vo Duy Tin, Deputy Head of the Department of Agriculture and Rural Development of Hoai An district, the chain of links will create a product that is similar in terms of fruit quality and quality. 19/4 Agriculture Cooperative will stand out to buy all products of farmers and sign contracts with businesses to sell the products. Mr. Tin said that the project on the chain of the 19/4 Agricultural Cooperative was built with a total investment of 25 billion VND, the heaviest cost was to build a preliminary processing house, cold storage to preserve products. warehouse and purchase cargo transport truck. This model is very necessary because in 1-2 years, the number of green pomelo areas to the business period in Hoai An district will grow very high. Up to now, the 19/4 Agricultural Cooperative has connected a focal point for product consumption with a business in Ben Tre. It is expected that, if successful, Hoai An pomelo can be exported to Europe and Korea.

Developing clean agriculture for urban service In Hoai An district, there is also Thanh Nien Agricultural Cooperative, linking the youth force of communes with farmers to buy clean agricultural products in the area. When associating with farmers, the cooperative will guide farmers to produce vegetables and fruits in the direction of clean agricultural products, then set up a stall selling clean agricultural products at the district center for consumption and for sale outside the province. In An Nhon Town (Binh Dinh), there are also many models of clean vegetable and organic vegetable production that are operating effectively in the direction of developing clean agriculture for urban areas in association with the project of restructuring the industry. local agriculture. For example, Yuuki Farm organic vegetable farm with Japanese technology by Mr. Trinh Hung Cong in Nhon Hau commune. Yuuki Farm is producing and trading clean vegetables, roots and fruits such as vegetables, lettuce, tomatoes, carrots … Every day, on average, Yuuki Farm sells about 100 kg of clean vegetables according to the order. of 2 kindergartens in Quy Nhon city with 7 points selling clean vegetables inside and outside the province. Every month, after deducting expenses, Cong’s farm gives a profit of about 60 million dong.

Also in Nhon Hau commune (An Nhon town), the project of producing organic vegetables in a net house of Kei’s Japan Joint Stock Company was born in 2016. Many varieties of vegetables such as lettuce, okra, cucumber, vegetables … were brought from Japan and cultivated according to Japanese technology on an area of ​​7,500 m2. As a result, local people have direct access to the way of making soil, fertilizing, and planting to produce clean and safe vegetables. Currently, every day Kei’s organic vegetable garden provides more than 100kg of vegetables, tubers and fruits to the market with prices ranging from 20,000 – 40,000 VND / kg. Mr. Duong Quan Sy, a farmer participating in the project, shared: Through the outreach process, the project participants now have a firm grasp of the cultivation techniques and the company also implements mineral products for the people, thanks That farmer’s income is also higher. “Grasping the needs of consumers, Nhon Tho Agricultural Cooperative 2 has turned to organic agriculture. Currently, the cooperative has planted 3.4 hectares of safe vegetables, tubers and fruits in the right direction. Focus on the use of manure and microbiological organic fertilizers derived from natural by-products. The entire vegetable growing area is covered with nets to limit weeds, fertilize according to the norm using the drip irrigation system with Israeli technology and the use of pesticides of biological origin, nanotechnology, ensuring time. cups during cultivation. Cooperatives also use insect nets, antifungal products composted with manure. The products of vegetables, melon, cucumber of the cooperative are trusted by consumers ”.

UEH students gather and classify garbage before carrying it to destruction. The main goal of the project is to build a model of school without rubbish, apply a zero-garbage solution in school waste management, and prioritize the refusal – minimizing – reuse of single-use plastic products. The product is not required, or cannot be composted. The program will be implemented in the first phase from April to the end of October 2021 at UEH Campus – Nguyen Van Linh. With the concept “just recycling is not enough”, while recycling plastic is also causing many consequences for human health and the environment, the Vietnam Zero Waste Alliance (VZWA) * for that “Practice without rubbish” is the most sustainable solution and create a circular economy for society. In particular, schools play an important role in raising awareness of young people about environmental protection. This is the premise for the idea of ​​implementing UEH – Zero Waste Campus project. The project is part of a strategy to build a No Spam model in the community, as a pilot at the University of Economics, HCMC. Ho Chi Minh City – Nguyen Van Linh campus with cooperation, consultancy and technical support from the Vietnam Spam Free Alliance. The specific objective of the project is that at least 70% of the total post-project surveyed people understand what it means to be No Spam; the amount of general waste going to landfills decreased by about 40%; persistent waste (including disposable plastic, unnecessary products, organic composting) reduced by about 30%; Organic waste is processed to become compost, recycled waste is collected and taken to the recycling facility; Reducing the use of unnecessary, disposable or non-compostable plastic products. In order to realize action goals, City University of Economics. Ho Chi Minh City (UEH) and the Vietnam Spam Free Alliance signed a cooperation agreement (MOU). The signed content of the two parties aims to jointly design, consult and plan the UEH – Zero Waste Campus project, including the development of measures to manage and reduce waste in the school and campaigns. improve waste awareness, adopt a No-Garbage lifestyle and turn waste into a resource. UEH students in class Mr. Bui Quang Hung – UEH Vice Rector shared: “Towards the model of“ Green University ”, HCMC University of Economics. Ho Chi Minh is actively cooperating with the Vietnam No Trash Alliance in activities of managing, minimizing and turning waste into resources; communicating and implementing a roadmap to build the No-Garbage School. The project expects all staff, students and stakeholders at the University to increase awareness of waste issues, and understand and practice the “No Spam” lifestyle. Accordingly, the Vietnam Non-Garbage Alliance initially surveyed students’ perceptions, assessed the current situation of waste at UEH campus – Nguyen Van Linh and will continue to coordinate with the school to implement specific activities. project roadmap. Ms. Quach Thi Xuan, Coordinator of the Vietnam Spam Free Alliance said: “The Zero Waste Campus project marks a new turning point in the partnership between UEH and the Vietnam Spam Free Alliance. This is a “long-term” program with special meaning to raise awareness of environmental protection with practical actions “. The project helps to limit plastic waste, protects the health of students and staff from the harmful effects of plastic waste, and at the same time contributes to building UEH – Nguyen Van Linh Campus in the direction of “Green University” – Green School , Environmental friendliness.

Surely you never expected this special use of onion skin, right? Onion peel contains color molecules, giving you a natural, safe, and non-damaging hair color.

You only need to boil a small handful of onions in the water for about 5 minutes. Cover the pot and wait for the water to cool. Strain and take out the water to wash your hair. Leave for a few minutes and then rinse with clean water. For a good effect, you can do this one more time.

Kill fungi and insects for plants

The scent of the onion peel makes the insects run away. You can use the bark to treat fungus and kill insects in your home garden by mixing 100g of onion skin with 500ml of water in a sealed jar. Leave the jar in a cool place for 7 days and then use.

When using, dilute the onion skin juice with clean water at a ratio of 1:10. Spray the solution evenly over the entire plant to kill fungi and insects.

Onion peels have many unexpected uses that housewives do not know.

Make compost

Like other fruit and vegetable peels, onion skin can also be used as an organic fertilizer for plants. The simplest way to do this is to bury the scallions in the ground so that they decompose naturally.

Used to bake bread

The onion skin functions as a dye. When making bread, you can add a little onion crust. The breads will have a more attractive and glossy yellow color.

Add flavor to soups

For a long time, when you cook soup, you still only use the onion to cook the soup without the peel. It is a waste. The rind, after being washed and added to the soup, can make the dish more delicious and taste sweeter than usual.

Want immediate effect

Dr. Nguyen Ba Phu, Department of Crop Production (Faculty of Agriculture, Can Tho University) said that in recent years, many gardeners renovate mixed gardens and a movement to establish specialty gardens in some localities is emerging.

Efficiency and profits increase if farmers know to invest in the right direction and apply the right care techniques. Currently in the Mekong Delta, the provinces of Soc Trang, Hau Giang, An Giang and Can Tho city … organize many training programs on cultivation techniques, cultivation of specialty orchards in the direction of sustainability.

Although understanding and understanding techniques to build specialized gardens in a sustainable direction, some gardeners still have not changed their practice in a new way.

The farming methods, applying new technical advances, training the majority of farmers agree, and think in the right direction. If you do, the garden will be “solid”, sustainable and completely applicable.

However, there are still some gardeners who believe that applying methodical techniques, the tree will take long to produce high-yield fruits, it takes time, because the psychological pressure of “eating in the same place”, wants to follow the tree to produce fruit. profit quickly, high profit even only 3-5 years.

Therefore, when realizing that the market for fruit varieties is attracting products for one or two consecutive years with high prices, they rush to find seeds to buy and plant for them. Some people are even ready to cut down orchards that are giving fruit if after only one or two seasons the fruit price falls and it is difficult to sell.

For example, some gardeners planting persimmon tangerines (also known as tangerines) in Lai Vung district (Dong Thap) admitted: Since 2 years ago, there were signs of pests and diseases “raiding” many orchards.

However, some gardeners still accept to pour billions of capital into tangerine gardens, even dig soil up, buy land from the fields and pour it in to hope to gain silver in the tangerine season.

However, due to the wrong care and prevention of pests and diseases, the disease has worsened and the garden gradually deteriorates. Some farmers often spread word of mouth to each other about prevention and treatment.

Pink mandarin trees have two quite common diseases, for each root rot disease, they buy Ridomil to control plant diseases, and mealybugs buy Nokaph (medicine to treat nematodes and pests in the soil), even in gardens that are not diseased. also bought for prevention before, every 2 months and considered as “miracle”.

As a result, as now seen, many pink tangerine orchards get worse and worse, they have to ask for help from scientific staff to find the right gardening method.

Currently, Soc Trang province organizes a training program on the model of building a special-purpose orchard specializing in citrus trees for farmers. Thereby improving knowledge, updating farming techniques, applying new technologies in fruit production. This model is applied by growers quite popularly in the fruit export cooperatives.

It is an open way to improve garden economic efficiency. The local government acts as a bridge to create a link between agricultural cooperatives – businesses – scientists. In which the role of scientist will guide farming techniques for cooperatives farmers.

Technical solutions for sustainable fruit production in the Mekong Delta

Dr. Nguyen Ba Phu proposed a number of technical solutions for planting and taking care of fruit trees in the Mekong Delta.

Select and improve soil: Soil has a pH of 6-7. The soil must be loose and airy, able to hold moisture and drain well, the arable layer is thick (at least 0.5 m) and stable.

Seedlings from good, selected seedlings, preferably from the best clones. There is an appropriate propagation method, free of diseases (special attention is paid to green leaf yellowing disease and Tristeza on citrus trees).

About the planting type, should be planted in rows. Rows in the wind direction (Northeast – Southwest). Spacing between thin rows, on thick rows.

Preparation of growing tissue and planting: All the soil above and below the base of the tissue (0.3 m) is soil mixed with organic fertilizer (5 – 10 kg) and fused phosphate fertilizer (0.5 – 1 kg). The tissue diameter should be about 1 – 1.2 m. The tissue height should be about 0.3 – 0.4 m. When placing plants, pay attention to the surface of the pot to be level with the tissue surface and tighten the soil around the pot.

Applying the process of pruning properly, creating canopy will help fruit trees for good design and quality. Photo: HD.

Trimming, creating canopy: Apply right in the stage of silk, from a young tree. Trees for fruits outside the canopy (citrus, mango, longan …) need to create a canopy with hemispherical shape or open heart, according to the principle of 1 branch leaving 2-3 branches (equally good, sparse, balanced).

Cutting time: Old leaves, just before or after fertilizing, combine bud control at the same time. For fruit trees on the main branch (durian, jackfruit …), create a crown shaped tree (pine canopy), keeping a main stem, growing straight.

Choose to keep level 1 branches (branches growing from the main body) with criteria for good branches, horizontal growth, evenly distributed, 20-30 cm apart. Can bend level 1 branches, creating the shape of a spiral staircase. Pay attention to keep level 1 branches during the fruit harvest.

Hygienic pruning should be carried out throughout the planting period, especially after harvest.

Cut off branches reaching high and shade (control canopy), pests, dry branches, branches that are not capable of bearing fruit … Keep appropriate canopy. Always leave a space between the two rows to help the garden clear. Keep a reasonable height of the garden for easy care and intensive farming.

Fertilize: Plants need to be provided with 13 essential nutrients: Macronutrients (N, P and K); intermediate (Ca, Mg and S); trace elements (Fe, Cu, Zn, Mn, B, Mo and Cl). In the Mekong Delta, fertilizers containing S should be limited, since most of the soil contains S in high levels.

Lime: should use limestone (CaO) “phi”, fertilizing in the beginning of the rainy season, fertilizing with soil pH. If the pH is above 6.5, there is no need for liming; pH from 5.5 to 6.5, applying 500 kg of limestone / ha; pH from 4.5 to 5.5, apply 1,000 kg of limestone / ha; pH from 3.5 to 4.5, apply 2,000 kg of limestone / ha.

Organic fertilizer: Chewable and properly composted. During the incubation process, it is necessary to pay attention to the appropriate humidity (about 70 – 80%) and to mix the compost pile. Applying in the dry season, the amount of fertilizer is 10-20 tons / ha. Do not use together lime and organic fertilizers.

Inorganic fertilizers: Need to determine the type and amount of fertilizer depending on the needs of the plant. Plants have different nutritional requirements depending on the stage of growth and each stage of fruit development.

In the period of silk (trees without fruit), fertilizers (N – P2O5 – K2O): 30 – 20 – 10 or 30 – 10 – 10. The amount of fertilizer is from 50-100 g / time. Fertilizer time when leaves are old, should not be applied when the leaves are young. Need to fertilize according to the canopy, burial or watering.

Reasonable vegetation should be maintained in orchards. Photo: LHV

It is advisable to combine cultivating and improving lettuce with fused phosphate, organic fertilizer and sedimentation. Micronutrients can be added by spraying leaves at silk leaves, combined with pruning measures, helping plants to sprout simultaneously. The type and amount of manure can be decreased depending on the type of tree, soil area, density and yield of the previous crop.

Note: Apply according to the canopy (active root zone). The manure must be buried in the soil (using a hoe or machine to mix the fertilizer).

Fused phosphate fertilizers (Ninh Binh, Van Dien, Lam Thao) should be used, especially on low pH soils in the Mekong Delta. In addition to containing phosphorus, molten phosphate also contains Ca, Mg, Si and some trace elements.

Grass management: Should let the grass in the garden, weeding clean the part close to the base, around should only cut, leave the grass stump about 3 – 5 cm.

Water management and irrigation techniques: Water systems in garden ditches must be well ventilated and downstream. Regularly change the water in garden ditches.

Keep the water level in the ditch about 0.6 m from the trench surface during the dry season and 0.8 m. In the rainy season, limit watering to the leaves. Do not water after 3pm. Best in the morning. Maintain a suitable soil moisture of 70 – 80%.

Pest management: Adopt integrated pest management (IPM), make full use of farming practices. Apply biological methods. Using agricultural medicine is the last resort and must adhere to the 4 correct principle.

How to exploit fruit and flower processing: should exploit fruit concentratedly. Should not “pass” fruit (many sizes of fruit) on the tree. Depending on the natural conditions, choose the appropriate time to process the flowering so that the fruit has good quality, high yield, less pests and strong plants. Keep a reasonable number of fruits (pruning) depending on the growth situation (leaf set) of the tree.

It is possible to combine the use of soil “cropping” method (about 30 cm deep) to both treat flowering and improve soil porosity and ventilation.
