First, grasp the fine varieties, do a good job of seed selection and germination test. To promote good soybean varieties suitable for the region, and avoid large-scale varieties of large-scale transport in long distances and across ecological areas without trial planting. Farmers are required to advance their own germination tests by exchanging seeds for self-sustaining, self-retaining and self-use, and seeds with low germination rates should be appropriately increased in seeding volume.
Second, early sowing when grab, enough to sow. The current situation is good, rapeseed, wheat crops after the close of the harvest, looting sowing, lack of lyrical watering after sowing first, the end of June 10 sowing.
Third, increase fertilizer material. Combining cultivating and cultivating rice stubble with high quality farmyard fertilizer 3000-4000 kg per mu, or soybean special compound fertilizer 20-25 kg.
Fourth, do a good ditch drainage. Do a good job in field drain ditch pit, open a good "three ditch", so that the rain to stay dry, no water in the ditch.
Fifth, control of underground pests and chemical weeding. The use of coated seeds or seed coating agents and phoxim and other seed dressings to prevent earthworms and other underground pests. Before soybean emergence, chemical herbicides were used to seal soil against weeds. Generally, 50 ml acetochlor EC 50 ml per mu was used to spray 50 kg of water on the ground.
Sixth, promotion of mechanical precision broadcast, uniform broadcast technology. Miao Quan and Miao Mian are the basis for high yield of soybean. Based on the guarantee of the germination rate and the number of seedlings, precision seeding, mechanical uniform seeding, or small area artificial precision seeding are adopted. According to the characteristics of soil strength and variety, a reasonable row spacing is selected. In general, medium-to-upper ground force uses a row spacing of 33 cm, 40 cm or 50 cm, or a width of 5033 cm.
VII. Check seedlings in time to ensure seedlings. After the emergence of soybeans, the seedlings shall be checked and seeded in time. Within 30 cm of the broken ridges, two plants can be left at both ends, and the replanting can be carried out in 30 minutes or more, or the shoots can be transplanted with soil water. After soybean seedlings are seeded and seedlings are seeded according to the required density and time, if the weather is dry or the pests are heavy, the seedlings and the seedlings can be divided into secondary treatments.
