High protein soybean cultivation technology

(1) Use high protein content varieties. Use high protein soybean varieties with protein content above 45%. Currently, Heilongjiang 16, Heidou 21, Yudou 22, and Xudou 9 have been promoted to meet the quality requirements for high-protein soybeans. Zhongdou 26 meets the quality requirements for high-quality combined soybeans and can be planted. (2) Selection of land and fertilization. Due to the reduction of 20--30% in heavy cowpea production, the reduction in production of 5-to-10% in soybeans. Therefore, it is best to choose high-protein soybeans that have no pollution, fertile soil, adequate water sources, and no weight. More than 1,000 kg of fertilizer per acre Shi Nong, even before the site preparation, fertilizer, NPK ratio of 1:2:1, generally 13 kg per acre of ammonium phosphate, potassium sulfate 5 kg, and seed layering Apply. (3) seed dressing. Soybean inoculation of Rhizobium before sowing is an effective measure to increase production. Method is: use a small amount of rice soup or water to make the paste into a paste, and then mix well with the seeds, placed in the shade, slightly dry and mix with a small amount of mud or grass ash, and finally mixed with phosphorus and potassium fertilizer, or add a small amount of molybdenum, boron , manganese and other trace element fertilizers, and then immediately sown. In molybdenum-, boron- and calcareous soils, ammonium molybdate, borax and manganese sulfate can be used for seed dressing, respectively, resulting in significant yield increase. (4) Field management. a. 50% Acetochlor 130ml plus 48% Promethium 50ml/25kg water per acre, sprayed immediately after sowing soybeans for pre-emergence soil treatment, have a strong inhibitory effect on a variety of weeds . b. cultivator. The cultivator has a variety of functions, such as the elimination of compaction, water conservation, conservation of weeds, promotion of survival and survival of rhizobia, and enhancement of nitrogen fixation capacity. Shallow-deep-shallow standards should be adopted and cultivators should be used for 2 to 3 times. The last cultivator can be combined with earth to prevent lodging. c. Drought prevention and drainage. From flowering to grain filling, high-protein soybeans have the fastest rate of water absorption and most water consumption. If the soil moisture is less than 25% at this stage, it will cause a large number of flowers and plants to fall. Irrigation should be controlled with groundwater irrigation and flood irrigation should be avoided. Usually every 5-7 days of irrigation once, continuous pouring 2 - 3 times, can protect the flower, increase production and quality. Soybean is also a kind of crop with poor waterlogging resistance. After flooding, it is easy to cause flowers to fall and fall. Therefore, attention should be paid to trenching and draining to prevent waterlogging. d. Top dressing. Soybean topdressing nitrogen fertilizer at the end of the pods can meet the needs of soybean pods for nutrients, but it will not cause prosperous growth, which will increase grain weight and increase yield. Generally, during the period of cauldron ditching, about 10 kilograms of urea can be applied per acre, which can also be applied to soybeans in combination with irrigation. If the fertilizer is insufficient, extra-root fertilizer should be applied during the grain filling period. Generally 0.5 kg of urea, 1.5 kg of superphosphate, 0.25 kg of potassium sulfate, extraction leachate, add 50 kg of water sprayed on the leaves, preferably in the cloudy or sunny after 4 pm spray, rain should be heavy spray. (5) timely harvest. Shaking soy plants sounded, and about 10% of the plants still harvested when the leaves did not fall, which was conducive to improving yield and quality.
