Last Updated: 2024/11/22, Technical points of flat cropping, narrow row and dense planting of soybean: first, seeds and treatment: variety selection according to local ecological types, suitable varieties according to local conditions. Second, seed quality: it is necessary to reach the seed classification standard of more than two improved varieties. Third, seed treatment: seed dressing agent is used to select seeds according to the types of diseases and insect pests and soil conditions. Fourth, rotation and ploughing and land preparation: rotation for more than 3 years, no stubble, no stubble, the first crop is mainly wheat crops. Deep loosening is mainly adopted in farming, with the combination of loosening and harrowing, in order to resist drought and preserve soil moisture. five

Technical points of horizontal cropping, narrow row and close planting of soybean:

1. Seeds and treatment: varieties are selected according to local ecological types and suitable varieties are selected according to local conditions.

Second, seed quality: it is necessary to reach the seed classification standard of more than two improved varieties.

Third, seed treatment: seed dressing agent is used to select seeds according to the types of diseases and insect pests and soil conditions.

Fourth, rotation and ploughing and land preparation: rotation for more than 3 years, no stubble, no stubble, the first crop is mainly wheat crops. Deep loosening is mainly adopted in farming, with the combination of loosening and harrowing, in order to resist drought and preserve soil moisture.

5. Fertilization: work with sowing in stages, fertilizing deep in autumn or applying layer by layer to 7 cm and 14 cm under planting.

Sixth, sowing: sowing time ground temperature stable through 7 to 8 degrees Celsius to start sowing.

7. Sowing method: horizontal planting with narrow rows and close planting can use a 24-row seeder to block a sowing hole. Sowing row spacing: 15 to 30 cm, in order to give full play to the population, individual comprehensive yield potential. Sowing depth: 3 to 5 cm after suppression. Sowing density: at present, the sowing density of varieties used in production can be 400000 plants per hectare, and the sowing density of reserve lines suitable for narrow row and dense planting is 500000 plants. Sowing quality: sowing evenly without broken strips.

Eighth, field management: 30 cm row spacing of flat sowing and dense planting, in the growth period can be shoveled twice.

9. pest control: heart-eating insects kill pyrethroids and other pyrethroids with 2.5% of their enemies.

Harvest: when harvesting, mechanical combined harvesting is carried out when all the leaves are clear and the soybean "rings".
