How many days does corn germinate? How many days after sowing?

When corn is sown in summer, it usually takes about 5-7 days to emerge. The sowing time in spring is a little longer, and it usually takes about 7- 10 days to germinate and unearthed. Excessive soil drought or high soil humidity will affect the emergence of corn, so it is necessary to choose suitable plots to sow corn.

Time and method of maize sowing

1, sowing date:

The sowing time of corn is usually divided into spring and autumn. Sowing is usually carried out from April to May in spring and before mid-July in autumn. Therefore, corn is also divided into spring corn and autumn corn because of planting time.

2. Land selection and preparation:

Corn is suitable for planting in fertile, loose and well-drained soil. Watering the soil in advance is beneficial to the rooting, germination and later growth of corn. It is advisable to dig holes in the land in a straight line with each other.

3, seed selection and sowing:

Select high-quality corn seeds with complete seeds, full flesh and no pests. When sowing, the temperature is kept at about 1 1, the plant spacing is kept at about 30cm, and 3-4 seeds are sown in each hole.

How to manage corn after emergence

1, fertilization:

After maize emergence, topdressing should be carried out according to seedling condition, leaf color and base fertilizer dosage. Three seedlings with thin seedlings, narrow and long leaves and yellow leaves should be pulled out in time, and topdressing should be done as soon as possible to increase the amount of topdressing.

2. Water:

Corn seedlings have a great demand for water, so it is best to water them in time to keep the soil basically moist, but water accumulation should be avoided, which is easy to rot roots in an environment with water, and drainage should be done in time in rainy season.

3. Pests:

Corn should be sprayed with pesticides to control pests during germination and seedling raising. For example, you can use dichlorvos mixed with sand to control grubs, sow evenly along corn seedlings in the morning and maintain them at all stages.
