1、 Sowing time

The suitable time for sowing sweet corn is spring, which is about March to may, and the sowing time in each region should be changed according to the change of weather. Don't do it when it's too hot. It's not conducive to its emergence, and even if the seedlings grow, they may be very thin seedlings. When it grows and matures, the yield will be very low

2、 Precautions for sowing

1. Land: the land for planting sweet corn should have good fertility and higher softness, so turn the soil and add an appropriate amount of base fertilizer before sowing

2. Variety: the selected seeds should have good lodging resistance. If they are planted in the north, the purchased seeds should also have excellent cold resistance. Whether the seeds are of high quality will directly affect the yield, so if you want to have a higher yield at the time of harvest, you need to buy high-quality healthy seeds

3. Intercropping: intercropping after sowing is also very important, because if the seedlings grow too dense, the seedlings will grow very thin, so remove the too dense seedlings in time
