Thach Ha: 3 kg radish model

(Baonghean) - When we arrived at the wild sandy beach of Thach commune, Thach Ha - Ha Tinh, we were surprised to see more than 30 hectares of green plants amidst the vast white sand.

Leading us out to the middle of the radish field, Mr. Nguyen Van Thuc - Director of the One Member Co., Ltd.

Mr. Nguyen Van Thuc with his achievements.

The most important "key" is to apply a "fixed and semi-fixed sprinkler irrigation" system invested in the entire cultivated area. Based on the characteristics of the variety, determine the appropriate humidity for each type of plant, to apply the most suitable irrigation regime, which is one of the effective intensive farming measures on poor sandy soil. Sprinkler irrigation is a method of using a high-pressure water pump with pipes and spray nozzles to create rain. This is a modern irrigation method that has many effects in both creating moisture for the soil and cooling the plants, stimulating plant growth and especially can save 30-50% of water volume compared to the method of flooding the furrows. With an investment level of a fixed irrigation system from 80 - 150 million VND/ha, depending on the terrain, the calculation shows that the break-even point is only after 1 - 2 cultivation cycles, about 4 - 6 months.

The superiority of the sprinkler irrigation method ensures that water reaches all areas of the land; improves soil permeability, cools the air; maintains suitable soil moisture for plants to grow strongly from the beginning; improves the efficiency of fertilizer use, reduces plant withering during the harvest and hot season.

Mr. Thuc added: In addition to the irrigation system, on sandy soil, it is necessary to calculate the drainage system. It is necessary to dig drainage ditches to ensure that water is always actively drained and not flooded during the production process. For low-lying areas, there must be a drainage pipe system (geotechnical pipes and geotextile rolls) to bring the amount of water seeping from daily rain into the drainage ditches, the groundwater level should be kept lower than 70 cm. This issue raises technical solutions on how to make beds, for each crop season and planting techniques of each type of plant. Second is the variety factor: The yield potential, quality and adaptability of the variety are the premise to create a large volume of products per unit area. Radish and rock cabbage varieties are imported from Korea and China. Liyou Seed and Goodseed 863 varieties can grow in winter, spring and spring-summer crops, with an average yield of 45 - 60 tons/ha. Particularly for Turnip Seed variety, the yield reaches 90 tons/ha, suitable for winter-spring crop. The Hong Kong high-yield tomato variety has a real yield of over 40 tons/ha.

Third, fertilizer must be invested at a high level of intensive farming, ensuring the correct process for each type of crop. For example, the investment level for fertilizer for radish (large root variety) calculated per sao (500 m2): humus taken from organic waste 1.2 - 1.5 tons; 45 - 50 kg NPK 16:16:8; Urea 8 - 10 kg; Potassium 20 - 22 kg and Boron 1 - 1.2 kg. Apply synchronous basal fertilization techniques before making beds and top dressing in furrows.

This company also only uses pesticides, only uses compounds of biological origin such as: Marshal 200 SC, Proclaim 1.9 EC.

By applying scientific advances in production, MITACO Agricultural Seeds and Materials Company Limited has succeeded, becoming a model for many provinces to visit and learn from.
