What if the latest corn is green and ripe late?

In the process of corn planting, it is sometimes found that the corn is greedy and green. It should have been the mature season, but the stems and leaves of the plant are still luxuriant and turquoise, as if they were not going to mature. Generally, such a situation is an abnormal growth phenomenon, so what is the specific reason for the formation of this situation, and what should be done?

1. The cause of greed for youth

The greed of corn is generally due to the late sowing and planting, which leads to the delay of seedling development. Or death malnutrition, such as carbon-to-nitrogen ratio is too small, will affect growth and development. Sometimes vegetative growth is too prosperous, it will be late to enter reproductive growth, plant overgrowth, late heading, growth delayed. The above are the main reasons, but do not rule out other reasons.

2. Promote development

Use a small amount of nitrogen plus phosphate fertilizer as seed fertilizer, loosen the soil after sowing, need water and fertilizer after jointing, promote the seedling jointing growth, and loosen the soil about when it grows to a few true leaves, which can improve the soil environment and promote root growth. it is beneficial to the activity of microorganisms, which is beneficial to the growth of corn and can promote early development.

3. Auxiliary measures

The empty stalks, or small plants in the field, do not bear corn, or the grafted corn is very small to remove, to avoid nutritional consumption, can also increase ventilation and light. Pollination is sufficient, and the remaining tassels can be removed after complete artificial pollination. After the female ear is shredded, the bracts need to be cut off to promote silking. Be careful to remove the invalid ear.

4. Weeding and topdressing

During the filling period, it is necessary to loosen the soil and weed, cut off some roots, promote soil permeability and increase the temperature. This can promote precocious, but can not cut off the root system, the source of nutrients and water are short, will die. If there is no drought and no watering, greed can also be prevented. In the silk-drawing period, topdressing fertilizer is about 200 jin per mu of chemical fertilizer. As long as the corn grows well, don't apply fertilizer in the later stage, it's easy to get green.

Corn is often prone to greedy green late ripening, affecting the quality and delaying harvest. Therefore, greed can be avoided by some measures in cultivation management.
