Last Updated: 2024/11/06, The main results are as follows: 1. the planting density, row spacing and plant spacing are determined according to the plant type and branching characteristics of the variety. The main stem type varieties of ① with dwarf, precocious and anti-nephew branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling density 1.8-25000 plants. 2. the planting density is determined by the level of soil fertility and management level. After the planting row spacing is determined according to the variety, the density should be adjusted according to the soil fertility and the level of water and fertilizer management. 3. Sow as early as you can. Early sowing can significantly increase yield and fat content.

The main results are as follows: 1. the planting density, row spacing and plant spacing are determined according to the plant type and branching characteristics of the variety. The main stem type varieties of ① with dwarf, precocious and anti-nephew branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling density 1.8-25000 plants.

2. the planting density is determined by the level of soil fertility and management level. After the planting row spacing is determined according to the variety, the density should be adjusted according to the soil fertility and the level of water and fertilizer management.

3. Sow as early as you can. Early sowing can significantly increase yield and fat content, usually sowing on June 10-20. When sowing, it is necessary to sow enough moisture to lay the foundation for the early squatting seedlings.

4. Use adjustable precision seeder or manual on demand.

5. And time to fix the seedling and replenish the seedling.

6. Densification measures. The density of ① in seedling stage was insufficient. When the field emergence rate is low and the density is insufficient, the seedling stage can be regulated by replenishing seeds and seedlings, increasing branch growth by fertilizer and water at branching stage, and promoting pods per plant by fertilizer and water at flowering stage. The density of ② is too high or too high. According to the key points of uniform planting technology, the density is generally not too high, when the density exceeds the best density of the technology. Water and fertilizer at flowering stage of ③. Water and fertilizer at flowering stage is the key measure to increase soybean yield. General mu topdressing urea 5-10 kg, according to the seedling situation to determine the amount of fertilizer. To prevent the field canopy, flowers and pods caused by excessive topdressing.
