Select high-quality seedlings, dense first and then sparse, and the planting density is determined according to the field conditions, 160-180 plants / mu, or 220-250 plants / mu. In the same year of planting, we still need to cultivate the main vine, and after planting, we also need to fix the shoot, ear, yield and leaves.

Water was irrigated once after each fertilization. In addition, proper control of nitrogen, increase of potassium, medium soil fertility pure nitrogen about 30 kg, potassium oxide about 40 kg. According to the phenological phase of water supply, fertilizer and water combination.

When the grains of soybeans are large, the deformed, diseased and injured fruits can be removed, and 60 grains can be retained per ear. Winter shears leave about 1,200 branches per mu, about 80 per cent, about 6 per cent, 7 buds and 3 buds per mu, and about 7000 buds per mu.
