【Main cultivation measures】

1. Plant seeds at the right time and plant them closely. Sow from late March to early April, and plant 3500-3800 plants per mu in single cropping.

2. Scientific fertilization. Apply plantar fertilizer, apply seedling fertilizer early, apply jointing fertilizer, and reapply ear fertilizer.

3. Strengthen field management. Pay attention to squatting seedlings, timely cultivation, drought resistance, drainage, and spraying growth regulators to control plant height and prevent lodging.

4. Prevent pests and diseases. Pay attention to the prevention and control of sheath blight, stem rot, cutworm, armyworm, armyworm, corn borer and other pests.
