When is the best time to sow summer corn?

The best time to sow summer corn is in mid-June each year. Before sowing, apply base fertilizer well, and after sowing, do a good job of checking seedlings and filling gaps. At the same time, pay attention to preventing and controlling the corn borer.

When sowing summer corn, pay attention to:

1. Seed selection and seed soaking

Choose varieties with strong drought tolerance (such as Dan 2, Shandan 902, etc.), sun them first and then soak them, soak the seeds in 55°C warm water for 8 hours, dry them in the shade, and then sow, striving for full seedlings in one sowing.

2. Seed dressing and sowing

Corn seed dressing can prevent the occurrence of diseases such as head smut, maize rough dwarf disease, stalk basal rot, and banded leaf and sheath blight. Generally, a matching insecticide + fungicide is used as the seed dressing agent. In addition, the sowing depth of summer corn is best controlled at 3-5cm, and the sowing density is determined according to actual conditions.

3. Fertilizer

If the field soil moisture is poor and too dry at sowing time, you can sow first, water once, and then fertilize (if you fertilize first and then water, broadcasting will cause waste, while furrow application is acceptable, depending on habit). In addition, after sowing, use one bottle of Yunongsi per mu, mixed with 100 jin of water, and spray to seal and kill weeds.
