1, fine soil preparation, the implementation of the autumn fall soil preparation. The depth of ploughing is about 25cm, and the standard of surface formation after turning is used. 2, a reasonable rotation, the implementation of clearing. Soybean and non-legume crops should be rotated for more than three years. 3, according to local conditions, use high oil, high protein soybean varieties. High-oil varieties include 9 farmers, 22, Jilin 58, Jilin 35, Changnong 13, Jilin 47, Jinon 9, Jiyu 54, and Jikedou No. 1. High-protein soybean varieties include Jilin 28, Tongnong 13, Tongnong 11, Tongnong 14, Jilin 40, Jiyu 63, and Jilin Xiaoli No. 4. 4, timely sowing, equidistant planting. Soybean cultivation uses equidistant, precision, and double-row abductor seedling mechanical sowing techniques. 5, due to land, species to determine the reasonable density. The suitable density in the central plain area is about 180,000 plants per hectare; the suitable density in the eastern mountainous and semi-mountainous regions is about 200,000 plants per hectare; the suitable density in the arid and semi-arid areas in the west is between 180,000 and 200,000 plants per hectare. 6, increase agricultural fertilizer, scientific application of chemical fertilizers. Hami application of 100-180 kg of diammonium phosphate, 45-75 kg of potassium chloride, or 7.5 kg of biological potash, 45-90 kg of ammonium nitrate. Hefei City Fertilizer 30-45 cubic meters. 7, to strengthen management, timely spade. 8, prevention and treatment of diseases, insects, rats, pests: aphids: hectares with 40% omethoate EC. Locust insects: 20% hectares of inulin were killed on hectares. Downy mildew: Use 5% of Formamide WP. Rat damage: Bromadiolone, chlordimecin sodium. 9, drought and irrigation during the grain period.
