abstract:
The invention discloses a close planting cultivation method of three corn plants in extra-large ridges, which comprises the following steps: selecting excellent hybrid corn varieties with close planting resistance, dwarf resistance, lodging resistance and pest resistance, and planting in wide and narrow rows, with a wide row spacing of100-150 cm and a narrow row spacing of 40-50 cm, with 3 plants per hole and 5700-6700 plants per mu. Apply more base fertilizer, spray herbicides after sowing, spray plant growth regulators, intertillage and cultivate the soil before closing the ridge, water twice, and harvest properly. This way can make full use of the advantages of lateral travel, and the ventilation and light transmission are more sufficient. It is not only convenient for field management, but also suitable for film mulching planting and drip irrigation, which can greatly improve the yield per unit area of corn. After 155 mu multi-point test, the average yield per mu increased by 244 kg.
