From mid-May to mid-June (1) Tillage and soil preparation. Summer soybeans are generally sown after winter crops are harvested. Due to the urgent time for harvesting and planting, in order to achieve early sowing, the methods of soil preparation shall be adopted according to the climatic conditions at that time and the specific conditions in the local area, respectively. It is 1.2-1.7 meters wide and 0.3 meters wide. (2) Seed preparation. Select high-yield summer soybean varieties; plots and fields with good fertilizer and water conditions; choose high-fertilizer conditions with larger grains; breeds with weaker fertility and field ridges; choose varieties with stronger adaptability and smaller grains . After selecting the varieties, sow seeds with good quality seeds. (3) Sowing amount. Summer soybeans generally use 4-6 kg of mu. The spacing is 0.3 meters and 0.5 meters. (4) Sowing period. After the winter crops are harvested, try to sow early according to the soil moisture. (5) Pay attention to the control of underground tigers and other underground pests. From mid-June to early July (1) make up the seedlings. Summer soybeans are sown at high temperatures and with rapid emergence. Soybeans should be seeded soon after emergence, and the soil after drying should be properly watered to protect the seedlings. (2) Dingling seedlings. Remove the seedlings and seedlings, leaving 10,000-1.5 million basic seedlings. (3) Lightly apply Miao Fei. Summer soybean seedlings have high temperatures and fast growth. It is necessary to properly control the amount of nitrogen fertilizers to prevent tall seedlings. Miao Fei mainly phosphorus and potassium fertilizers. Generally, 3 kg of urea, 25 kg of phosphate fertilizer and 10 kg of potassium fertilizer are applied. (4) Weeding and weeding. It is best to combine shallow early tillage with appropriate amount of soil. (5) pay attention to control locusts. From mid-July to mid-August (1) Deep cultivating high earth. (2) Pay attention to drought protection and seedlings. (3) Prevention of leaf-feeding pests. From mid-August to early September (1) Topdressing flower fertilizer. At this point, the growth of summer soybeans has entered the flowering period, which is the fastest time for vegetative growth and reproductive growth of soybeans, and it is also a period of special fertilizers. Therefore, to make summer soybeans with high yields, it is one of the keys to good flowering. Generally urea 5-10 kg can be applied, potassium fertilizer 5-8 kg. (2) Prevent drought and insect pests, and keep flowers. From mid-September to early-October (1) Cultivate outside the roots during grain stage. (2) Increase grain weight by drought prevention. Harvest, threshing, and drying seeds from early October to early November.
