Over the years, farmers northern provinces selected multi-element fertilizer (DYT) NPK Van Dien specialized in fertilizing rice crops with outstanding efficiency, the product lines of DYT NPK Van Dien fertilizer have 13 nutritional components, the ratio of nutrients depends on Depending on the type of fertilizer used for priming or for top dressing. According to local custom and also due to market demand, rice variety structure In the northern mountainous provinces, it is quite abundant: in addition to cold rice varieties such as hybrid rice, short-term pure rice KD18. Vnr20… group of semi-photosensitive rice varieties such as U17, U19, or tall sticky rice varieties; In many places, special photosensitive rice varieties are planted such as Bao Thai, yellow flower sticky rice… (Dinh Hoa – Thai Nguyen area). These are high quality rice varieties, but the percentage of flat seeds is high and it is easy to fall if lack of phosphorus and other medium and micro nutrients. From the agronomic characteristics of rice transplanting, as well as nutritional requirements, specialized NPK fertilizer Van Dien provide nutrients for rice plants, from transplanting to the time of flower differentiation (Nutritional growth stage). The fertilizer product lines DYT NPK Van Dien have all 13 nutritional ingredients Research on physiology and nutrition of rice shows that: The life of rice plants can be divided into 2 growth stages: vegetative and vegetative. The vegetative growth stage was counted from the sowing rice to the female standing rice. Crop season, this period usually lasts about 30-35 days with short-term cold varieties; (In particular, the photosensitive rice varieties must wait for a “short day”, which is close to the Bach Lo period, before the rice changes to the vegetative stage). At this stage, the roots develop in the shallow soil layer (about 3-5cm) and in the direction of spreading according to the cover of the rice leaves, when the set of rice leaves covers the row, the rice roots are also woven into the field. this period rice focus on tillering, spreading leaves, spreading sheath to make false stems, so the most nutritional needs are protein, potassium and less phosphorus and other medium and micronutrients. DYT NPK fertilizer specializing in fertilizing rice has many different formulations such as: multi-factor fertilizer NPK ( 16 :5 :17) has a content of N 16%, P2O5 5%. K2O 17% Mg 5%, SiO2 7%, CaO 8%, S 2%, etc. Currently, many places people use NPK . formula 13:3:10 +TE. These are fertilizers with high nutritional content of nitrogen, helping rice plants to lay strong, grow leaves, and grow stems. The nutrient content of potassium is quite high in the fertilizer to promote moderate tillering. In addition to the balance of NPK substances according to the needs of rice plants at tillering stage, there are also enough medium and micronutrients to help rice plants grow healthy, hard rhizomes, good resistance to pests and unfavorable environment. The stage of vegetative growth was calculated from the time of differentiation of the stem to the maturity of the rice. The long-term rice varieties have the time to stand female, while the short-term rice varieties usually do not show the time when the rice is female, but the rice plants may still have tillering but have differentiated. The time of transition to the vegetative stage is counted from when the rice leaf set is more upright, the leaves are “equal to the head” or when the rice begins to harden and round the base. From here, a second layer of roots develops into the soil layers below; When the rice plant blooms, it is the time when the trunk reaches its greatest height, the roots also go down to the plow layer and reach the greatest “depth”. Providing enough nutrients at this stage helps the process of making poles, favorable flowering, good and durable leaves and large flowers, many seeds. In addition to the micronutrients, rice plants need a lot of phosphorus and NK balance to differentiate flower sprouts, especially high silicon content to help harden the root, stem, and stand the leaves to increase resistance to pests and sugar accumulation. flour. NPK fertilizer specialized in fertilizing rice has many different formulas such as: NPK NPK 6:12:3 or NPK 5:12:3 , 10:10:5, 10:7:3 or multi factor rice fertilizer 1 specializing in fertilizing rice with sufficient and balanced nutrients NPK and micronutrients necessary for rice plants in the growing and flowering stage. Multi-element fertilizer (DYT) NPK Van Dien specializes in fertilizing rice crops to help achieve outstanding efficiency Cultivating seasonal rice in the northern provinces with fertilizer DYT NPK Van Dien: Manuring : Depending on the foot of the field, rice variety and the amount of organic fertilizer, balance the amount of fertilizer in the crop; average about 15-20 kg / sao. High-legged fields, less rice transplanted, less fertilizer, low-lying fields, more acidic, more rice transplanted, more fertilized, especially Bao Thai rice fields, tall sticky rice trees.. need to give priority to lining fertilizer, can fertilize 20-25kg/pole. In order for the fertilizer to be mixed evenly and sent to the soil layers below, meeting the nutritional needs of the rice growing and flowering stage; manure should be spread evenly on the field before harrowing for transplanting or before the last harrowing turn; If you are worried about dehydration or loss of manure, you can spread manure right after the harrowing is completed, when the water is still cloudy and the mud is still loose. Do not apply fertilizer after the water is clear, the mud has settled. Because when the sludge is settled, the nutrients have been attached to the soil grain and sink, in the water at this time only the substances that cause acid and alum remain, which are toxic to the rice roots. Therefore, to settle the sludge, in the water for 1-2 days, remove the clear water and then sow. Dressing: .Based on the bottom of the field, the amount of NPK multi-factor fertilizer applied as a primer and the growth situation of each rice variety that fertilizes seasonal rice as follows: – Thickly transplanted rice fields, large transplanted fields, low-lying fields… Fertilize about 8-12 kg / pole. – The fields are fertile, high, or dehydrated. High yielding rice varieties need to be fertilized about 12-15kg/sao. -The swampy fields, Bao Thai rice fields, tall sticky rice, or other easy-to-fall rice varieties… reduce the amount of fertilizer, (you can even remove fertilizer) and should only fertilize when transplanting. 7-10 days. – Particularly, the foot of the field is high and rapid, the rice variety is hard-bodied, the fertilizer is applied twice: 60-70% of the fertilizer is applied when the rice is ready to burn, and the rest of the fertilizer is applied. To reduce fertilizer loss due to evaporation, leaching or leaching, etc., fertilizer should not be applied when it is hot and when the field is full of water. Fertilizer should be applied when it is cool and the field is dry.

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.

From the Observation Deck, the soldiers could have a panoramic view of the Muong Thanh valley. Therefore, there are often scouts and information soldiers monitoring the situation of Dien Bien Phu campaign headquarters. The journey to discover and experience when going to the top of Pu To Co starts from Kha village with a distance of more than 4 km following the trail of the people in the area. In which, the first 3 km, the road is quite easy to go, the rest of the road is quite steep. The journey from Ban Kha to the top of Pu To Co is about 4 km long. The first 3 km is quite gentle, following the trails of people in the area. Along the way, quite a few flowers bloom purple on the side of the mountain. Visitors also encounter a lot of fruits and products. Many kinds of fancy flowers on the climbing journey. However, for many people, the forest journey consumes a lot of energy. About the last 1 km, the road is quite steep. Can’t even see the path without a guide marking it. About the last 1 km of the journey there is an abandoned house on stilts, where it is a rest stop before reaching the top of the Dien Bien Phu Campaign Observatory. For those familiar with the forest road, the distance of more than 4 km takes more than 1 hour. However, for most tourists, the journey will take 4 hours. Over the years, traces of the Observatory have disappeared. Therefore, the landmark marking Pu To Co peak will create a highlight for visitors to check in. Dien Bien tourism industry expects this to be a new destination for those who love to explore and learn about the nation’s history. Photo: PRED

Cluster of Dien Bien Phu Victory Monument on hill D1 (Photo: REDSVN) Dien Bien Phu Victory Monument is the pride of the people of Dien Bien province. This is also a stop not to be missed every time visitors come to the historical heroic land of Dien Bien. Hill A1 Hill A1 is located in Muong Thanh ward, Dien Bien Phu city, Dien Bien province. During the Dien Bien Phu campaign, hill A1 was located in a particularly important strategic position, considered the “throat” protecting the central subdivision, directly protecting General De Catries’ basement. The name A1 is the military name we gave to this hill, and before this hill had different names such as Lang Chuong, Eliane2. Remnants of the Hole Destruction on hill A1 (Photo: NDO) On the top of the hill there is a entrenched cellar, which was the wine cellar of the French legation before 1945. After parachuting over Dien Bien Phu, the French army consolidated the underground cellar into a military base. The cellar is divided into two compartments, in which one compartment is the working place of the radio communication department. The cellar is made of extremely strong materials, four sides are solid brick walls, the roof of the tunnel is poured with thick concrete layers, when necessary, it can be used as a hiding place for dozens of people. On the A1 hill, there are still traces of the Explosive crater formed by 960kg of explosives. Today, coming to the A1 hill monument, you can experience a number of practical activities such as: cooking rice for soldiers with Hoang Cam stove, pushing a bicycle to carry necessities, listening to stories about the Electricity campaign Bien Phu and soldiers’ activities in battle. National Martyrs Cemetery Hill A1 Located not far from the A1 hill historical site (Dien Bien Phu city) not far to the south, opposite the Dien Bien Phu Historical Victory Museum, Hill A1 National Martyrs Cemetery was built in 1958. Hill A1 National Martyrs Cemetery (Photo: dulichdienbien) This place is the resting place of 644 army officers and soldiers who heroically sacrificed to defend the country during the Dien Bien Phu campaign. In 1994, the cemetery was renovated, planned and built into a cultural and historical work, a park cemetery with many items. Inside the campus is a manor house designed in the style of a typical stilt house of the Thai people of Dien Bien, the outer stage is designed in the style of Khue Van Cac, flanked by two types of ancient city walls with two moats in front. 6m wide, outside the wall is an embossed relief depicting the heroic fighting of our army and people and nine years of long resistance to regain national independence. Tunnel De Castries Dubbed the strongest bunker in Indochina for a time, General De Castries’ command bunker in Dien Bien Phu was built very well by the French colonialists, in the center of the Dien Bien Phu fortress group, in the field. Muong Thanh, Dien Bien district, Dien Bien province. De Castries tunnel remains intact (Photo: REDSVN) Currently, the structure and layout and arrangement of the basement are still preserved. Around the bunker is a defensive fence with a dense system of barbed wire and four tanks. De Castries tunnel is 20m long and 8m wide, including four compartments used for both the residence and work of General De Castries and his soldiers. Dien Bien Phu Campaign Command Headquarters The monument of Dien Bien Phu Campaign Command Headquarters in Muong Phang is located at an altitude of over 1,000 m above sea level, hidden under the canopy of ancient forest, at the foot of Pu Don mountain, about 40 kilometers from the center of Dien Bien Phu city. kilometer. Overview of the relic site of Dien Bien Phu Campaign Command (Photo: dulichdienbienphu) Muong Phang is the third and last location of the Third Command of the Dien Bien Phu Campaign (from January 31, 1954 to May 15, 1954).

Dien Bien Phu campaign headquarters is hidden in the old forest at the foot of Pu Don mountain in Muong Phang commune, nearly 40 km from Dien Bien Phu city. This is where General Vo Nguyen Giap and his comrades from Dien Bien Phu Campaign Command usually work and rest. Dien Bien Phu Campaign Command Headquarters in Muong Phang Commune (Dien Bien Phu City, Dien Bien Province) – a historical site associated with the Dien Bien Phu Campaign “splendid in five continents, shaking the globe”. Along with the Dien Bien victory relic complex, the Dien Bien Phu Campaign Command relic and the auxiliary tourist site are always “red addresses” attracting tourists to come back when they set foot on the land of Dien Bien – Tay. North Country. With the arrangement of tunnels and camps into a continuous system, hidden in the old forest at the foot of Pu Don mountain, within 105 days from January 31, 1954 to May 15, 1954, the important headquarters of the campaign. Dien Bien Phu is absolutely safe. The road leading deep into the headquarters of the Dien Bien Campaign Command has been upgraded with a concrete road through the Muong Phang forest with a length of more than 1 km to help visitors recall old memories. From this headquarters, going to the highest point, you can observe the entire Dien Bien Phu city, Muong Thanh valley and former French strongholds such as Him Lam hill, Doc Lap hill, D1 hill, hill.

The historical site of Dien Bien Phu battlefield is historical evidence of the illustrious victory of the Vietnamese people in the long-term resistance war against the French colonialists, demonstrating the will and determination of the whole nation in front of a military force. mighty, modern war means With special significance and stature, the historical site of Dien Bien Phu Battlefield was ranked as a special national relic by the Prime Minister in 2009. However, there are still a number of places that are marked by the campaign This history has not been identified inventory, scientific profiling to rank. From the top of Pu To Co, you can look at Muong Thanh valley, Dien Bien Phu city today. Therefore, the additional research on Dien Bien battlefield relic sites continues to be carried out. After a period of collecting and supplementing, in December 2015, the Prime Minister signed the Decision on ranking and adding 23 relic sites to the historical complex of Dien Bien Phu Battlefield; including the Dien Bien Phu Campaign Observatory located on the top of Pu To Co mountain. According to the announcement of the Department of Cultural Heritage (Ministry of Culture, Sports and Tourism), the Dien Bien Phu Campaign Observatory relic in Muong Phang has an area of ​​160m2 of protected area I and protected area. II is 5,230.5m2. Pu To Co mountain was chosen by Chief of Staff Hoang Van Thai to set up the Observatory, located near the Operation Headquarters. The Operation Command was stationed in the forest of Muong Phang. The observatory of the Headquarters stationed on the top of Pu To Co was kept absolutely secret, from the time it was moved to the end of the campaign. According to documents of Dien Bien Department of Culture, Sports and Tourism, Pu To Co peak has an altitude of 1700m, the highest of the three mountains of Pu Don mountain range. The observatory is located near the headquarters in the forest of Muong Phang, at the foot of the Pu Don mountain range. At the observatory, there are always soldiers scouting, observing the Dien Bien Phu stronghold and reporting the situation to the headquarters. On May 6, 1954, General Vo Nguyen Giap went to the Battle Observatory before deciding to switch to a general offensive. After 56 days and nights of fierce fighting, the Dien Bien Phu campaign was completely won on May 7, 1954. Survey to find new destination đến To better understand the relic site, Dien Bien Department of Culture, Sports and Tourism has also organized a number of times to survey and determine the location of the Observation Deck on Pu To Co peak, but the traces are no longer present. The journey to Pu To Co peak starts from Kha village, Muong Phang commune (Dien Bien Phu city, Dien Bien province) with a distance of more than 4km following the trail of people in the region. The survey team took pictures on the top of Pu To Co, where the Observation Deck was located during the Dien Bien Phu campaign. On the road leading the survey team to the top of Pu To Co, Mr. Lo Van Hoang, head of the protection of the Muong Phang relic site, said: For skilled foresters, it only takes about 1 hour to climb to the top, but for those who are proficient in the forest, it only takes about 1 hour to climb to the top. It usually takes about 4 hours going up and 2 going down. Nearly the first 3 km, the trail is still gentle, along the mountainside, it is easy to go, creating conditions for visitors to just go and watch the flowers to buy, forest passion fruit, medlar (apple and cat) … However, the last 1 km is steep. tall, slippery, with many dense trees, so few people set foot there. Therefore, to get to the top of Pu To Co at the end, sometimes visitors have to pass through the forest trees, need local people to guide because many paths are difficult to identify. From the top of Pu To Co, on a clear day, you can look at the Dien Bien Phu basin, enjoy the panoramic view of Pa Khoang lake and Muong Thanh basin. Ms. Pham Thi Thao, Deputy Director of Dien Bien Provincial Monuments Management Board said: Due to the remote location, this relic site is still little known. The unit also organized several times for officials of the Board to survey with the purpose of making people understand better about the sites under management. The survey by the press and businesses and placing a pyramid symbol marking the height of the mountain peak and the location of the Dien Bien Phu Campaign Observatory will form a check-in point and attract tourists who love to explore in the near future. . According to the opinion of Hanoi travel businesses participating in the survey, this is a destination suitable for trekking to better understand a relic site that plays an important part in the Dien Bien Phu campaign. However, to become a tourist destination, first of all, the route to Pu To Co peak will soon install road signs because there are many trails, and at the same time set up a garbage collection point in combination with community tourism services. Climbing mountains and forests is also an experience to show the younger generation the hard work and hardship that their fathers went through to get the famous Dien Bien Phu victory in 5 continents, shaking the world.

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 provincial Ha Tinh there are more than 7,000 ha of citrus trees, of which orange and pomelo trees account for nearly 90%. The most cultivated area for pomelo trees is in Phuc Trach, Huong Trach and Huong Do communes (Huong Khe district), while the orange area is mainly concentrated in Vu Quang district up to 2,500ha, Thuong Loc commune (Cam Loc district) is 240 ha.

Land for planting oranges and pomelo This area belongs to the group of red and yellow feralit soil and an area of ​​basalt soil formed on hilly or mountainous terrain interspersed with high mountains, very hot summer climate, on average 380C, cold winters and rainfall. Large, suitable for grapefruit, orange trees.

However, in the agronomy of pomelo and oranges, there are many limitations due to the unscientific use of fertilizers, farmers rarely invest in organic fertilizers, use too much acidic chemical fertilizers such as supe, phosphorus, nitrogen, etc. or types of fast-soluble NPK containing acid root for fertilization, intercropping legumes for land investment is limited, and in the rainy season, soil is very large.

As a perennial tree, pomelos and oranges in Ha Tinh lack nutrition and sour environment, thus reducing productivity, appearing harmful pests and diseases. Before 2010, the brand name of Phuc Thach pomelo and oranges in the market was faint. The area of ​​orange cultivation has narrowed, the gardeners’ income has decreased sharply … in order to restore the brand, regain productivity and quality, Ha Tinh province has focused on investing in building a fertilization process according to the VietGAP standards.

Understanding local needs and shortcomings in the use of fertilizers by farmers, Van Dien Fused Phosphate Joint Stock Company cooperates with Ha Tinh Gardening Association to deploy many models. using Van Dien fertilizer for pomelos, oranges and safe vegetables on the table in Huong Khe, Vu Quang, Duc Tho …

Trial on Van Dien fertilizer in pomelo production areas of Phuc Trach, Cam Khe May, Thuong Loc, Cam Bu Huong Son.

The experiment was conducted in a closed crop year 2010 on 1.5 ha of 15 year old grapefruit in Phuc Trach, together with 2.0 ha of 10 year old oranges in Khe May and Huong Son by using completely Van Dien fertilizer including Fused phosphate fertilizer and NPK multi-factor fertilizer is used specifically for citrus. Van Dien fertilizer divided fertilizer 4 times a year:

• Stage 1: Applying after harvesting, using 1.5 – 2.0 kg / root of Van Dien fused phosphate + multi-element of NPK 5.10.3, from 2- 4 kg + 15 kg of decomposed organic fertilizer /origin.

Phase 2: Applying flowers with the amount of fertilizer from 1.0 -1.5 kg / root of ĐYT NPK 12.5.10.

Stage 3: Applying after fruiting from 2.0 to 3.0 kg / root of health care NPK 12.8.12

• Phase 4 fertilizing 50 days before harvesting fruit from 1.5 -3.0 kg / root ĐYT NPK 12.7.20.

Grapefruit fertilized with Van Dien is more prominent than the control along with other NPK fertilizers in that: Bright green leaves, shiny leaf surface, thick leaves, smooth bark and branches, 50% reduction of harmful pests and diseases. high fruiting, fruit uniformity, concentrated ripening, beautiful peel color, less fruit drop, yield 1.8 times higher than control, sweet and fragrant quality characteristic of Phuc Trach grapefruit and famous Buu before. After only 10 years, farmers have liked the effectiveness of Van Dien Fertilizer
