How can soybeans grow high yield in summer?

How can you grow soybeans in summer to get high yields? Please also have experienced netizens to help list detailed steps soybean, not only food crops, but also industrial raw materials and feed crops, its nutritional value is second only to meat, milk, eggs, protein content as high as 40%, its branches and leaves can also fertilize the field, cultivate soil fertility, so the planting network sorted out the methods of planting soybean yield increase, the following are listed in detail for netizens reference. Method 1. Selection of soybean varieties: Soybean seeds should be selected with high yield, stable yield, good quality, strong resistance, wide adaptability, high yield potential and conforming to variety standardization, such as Xudou 9, Zhonghuang 13, Hedou 1, Yudou 22, 25, etc. Seed purity is not less than 98%, germination rate is above 85%, and seeds are sown after selection treatment. Method 2: Formulated Fertilization: Soybean fertilizer amount can be applied by mu organic fertilizer (2000 kg) phosphorus fertilizer 30-40 kg, urea 10 kg (of which base fertilizer accounts for 60% of the total, flowering chase 40%), potassium deficiency plot mu potassium sulfate 10 kg, boron, molybdenum, zinc and other trace fertilizers appropriate foliar topdressing, fertilization to base fertilizer mainly. Method 3: Soybean early sowing in time: Because early sowing in due time can improve the protein content of soybean. The suitable moisture content for soybean sowing is 19%-20%. If the moisture content is insufficient, it should be planted with soil moisture or rain; if the moisture content is too much, it should be properly scattered before sowing. The sowing depth is consistent, generally 3-5 cm, the seeds are evenly distributed, and the seeds are sown as early as possible, no later than June 25. Method 4: Precision and uniform sowing: Soybean is sown with precision, uniform sowing or machine sowing, sowing row spacing is 25- 40cm; or wide and narrow row planting is 50cm, narrow row is 25cm, sowing depth is 3- 4cm, after sowing, soil is evenly covered to preserve moisture, and closed herbicide is sprayed evenly in time to prevent and control weeds in seedling stage. Method 5. Management of soybean seedling stage (about 20 days from mid-June to mid-July): In the soybean seedling stage to timely thinning seedlings, fixed seedlings. Thinning refers to pulling out redundant seedlings after seedling completion, eliminating weak seedlings and sick seedlings. Seedling determination refers to the last thinning according to the predetermined row spacing and the number of seedlings left. Generally, the seedlings are thinned 2-3 times. Thinning of soybean seedlings can generally increase yield by 15%-20% compared with non-thinning, especially in years with large sowing amount, fertile soil and more rainfall. Soybean seedlings should be thinned early rather than late, generally in soybean cotyledons exposed to the ground, cotyledons open when. Deep cultivation and weeding can reduce the consumption of soil nutrients by weeds, cut off soil capillaries, preserve moisture and prevent drought, loosen soil to promote root development, and cut roots to control vigorous growth. Pay attention to the prevention and control of bean stalk flies, aphids and red spiders. Method VI. Management of soybean flower pod stage (from mid-late July to mid-August, about 20-30 days): The flowering and pod stage is the most vigorous period of soybean growth and development, which requires a lot of nutrients and water. Timely watering to prevent drought, increase flowers and protect pods, the soil moisture content is not lower than 75-85% of the field water capacity, combined with watering, urea 3-4 kg per mu. At the same time, attention should be paid to the control of bean moths, bridge-making insects, pod borers and fruit borers. Method VII. Management of soybean seed filling stage (about 35-40 days from the first half of August to the middle of September): The main task is to adjust fertilizer with water, raise roots and protect leaves without premature aging. Reasonable irrigation and drainage, drought resistance and drainage. At the early stage of grain filling, soil moisture content should be kept at about 70%-80% of the maximum water holding capacity in the field. If it is lower than this index, irrigation should be carried out in time, and irrigation should not be carried out until leaves wither. After heavy rain and rainstorm, the ditch should be cleaned and drained in time to prevent poor soil ventilation and affect normal development. At the same time do a good job foliar fertilizer, in order to help soybean bulging. We should also continue to control bean moths, bridge-making insects, etc., to protect leaves from damage.
