Soybean is not only a food crop, but also an industrial raw material and a feed crop. Its nutritional value is second only to meat, milk and eggs. The protein content is as high as 40%. Its branches and leaves can also fertilize the land and cultivate the soil. Therefore, Huinong.com The method of increasing soybean yield by planting is compiled for your reference. 1. Selection of soybean varieties: Soybean species should choose seeds with high yield, stable yield, high quality, strong resistance, wide adaptability, high yield potential, and standardized varieties, such as Xudou No. 9, Zhonghuang 13, Hedou No. 1, Yudou 22, 25, etc. . The seed purity is not less than 98%, the germination rate is above 85%, and the seeds are sown after the selected treatment. 2. Formulated for fertilization: The amount of soybean fertilization can be 30-40 kg of organic fertilizer (2000 kg), 10 kg of urea (including 60% of the total base fertilizer, 40% of the flowering period), and 10 kg of potassium sulfate in the potassium-deficient plot. Appropriate foliar application of boron, molybdenum, zinc and other micro-fertilizers, and fertilization is the main fertilizer. 3. Soybean timely broadcast early: Because of timely sowing, it can increase the protein content of soy. The suitable moisture content for soybean sowing is 19%-20%. If the sensation is insufficient, it should be smashed or raided by rain; if there is too much water, it should be properly sown and planted. The sowing depth is consistent, generally 3-5 cm, the seeds are evenly distributed, sowing as early as possible, no later than June 25. 4. Precision leveling: Soybeans use fine on-demand, uniform sowing or machine-casting, sowing distance 25-40 cm; or wide and narrow row planting, wide line 50 cm, narrow line 25 cm, sowing depth 3-4 cm, flattening and covering soil after sowing, timely use The enclosed herbicide is sprayed evenly to prevent weeds in the seedling stage. 5. Management of soybean seedling stage (mid-June to mid-July, about 20 days): In the soybean seedling period, time and seedlings should be fixed. Intercropping refers to the removal of excess seedlings after the seedlings, eliminating weak seedlings and diseased seedlings. Fixed seedlings refer to the last seedlings according to the predetermined row spacing and seedling number. Generally, the seedlings are 2-3 times. Soybean seedlings can increase yield by 15%-20% compared with non-breeding seedlings, especially in the years when the planting volume is large, the soil is fertile, and the rain is more. Soybean seedlings should be taken sooner or later, usually after the soybean cotyledons are exposed to the ground and the cotyledons are opened. Deep cultivating and weeding can reduce the consumption of soil nutrients by weeds. At the same time, it can cut off the soil capillary, protect the drought, loosen the soil to promote root development, and have the effect of cutting roots. Pay attention to the control of bean worms, mites and red spiders. 6. Management of soybean flower pod period (mid-July, mid-August-August, about 20-30 days): In the flower pod stage, soybean vegetative growth and reproductive growth progress, and soybean growth and development during the most prosperous period, requiring a lot of nutrients and water. Watering, drought prevention, flowering and pod protection should be carried out in a timely manner. The soil water content is required to be no less than 75-85% of the field water holding capacity. Combined with watering, the urea is applied 3-4 kg per mu. At the same time, attention should be paid to the control of the hawk moth, the bridge worm, the pea pod and the heartworm. 7. Management of soybean blasting period (from mid-August to mid-August, about 35-40 days): In the soy blast season, the high-yield water should be filled. The main task is to adjust the water and nourish the leaves. Reasonable irrigation and drainage, drought relief. In the early stage of drum granulation, the soil water content should be kept at 70%-80% of the maximum water holding capacity in the field. Below this index, timely irrigation should not wait until the leaves are wilting before watering. Huinong.com Xiaobian warmly reminded that planting summer soybeans should clear the ditch drainage after heavy rainstorms to prevent soil aeration and affect the normal development of soybeans. At the same time, do a good job of foliar spray fertilizer to facilitate soybean granules. It is also necessary to continue to control the larvae, bridgeworms, etc., to protect the leaves less damaged.
