Embodiment 1
[0031] A cultivation method for improving soybean yield potential, comprising the steps of:
[0032] S1. Seed selection, select soybean varieties with lodging resistance, high yield potential, dwarf stalk, semi-dwarf stalk, convergent plant type, high quality, high yield, high protein, and high oil;
[0033] S2. Seed treatment, screening high-quality seeds, coating the screened seeds, using soybean seed coating agent for coating treatment, fully mixing and stirring the soybean seed coating agent and soybean seeds according to the ratio of drug to seed ratio of 1:260;
[0034] S3. Farmland treatment, for subsoiling of farmland, the depth of loosening shall not be less than 35cm. During the subsoiling process, the soil shall be refined so that the radius of the soil block is less than 2cm. After that, ridges shall be formed with a width of 32cm and a height of 35cm, and drip irrigation shall be laid between the ridges. Deep fertilization at the same time as the ridges, the ferti...
