Analysis of the reasons why corn is not sticking

Corn is one of the main foods produced in China. So, in this section of the agricultural knowledge network, I would like to ask the corn growers, has your family's corn been unsatisfactory? Today, the agricultural knowledge network Xiaobian will analyze the growing cornfield with everyone, why is there not a corn cob!

Xiao Bian believes that many friends have met more or less, I saw that the corn stems are long and do not see knots. Why? In recent days, the Agricultural Knowledge Network Xiaobian found that many friends on the Internet mentioned this matter. The small area still has little effect. In some photos sent by friends, the whole piece of land is like this, and it can only face the failure. Therefore, Xiaobian of the Agricultural Knowledge Network feels that it is necessary to tell everyone about this situation.

First of all, what are the reasons for the lack of good corn?

1. Seed reasons

Putting the seed reason first, it is very important. When buying corn seeds, buying fake seeds, Chen seeds, and varieties that are not suitable for local planting may cause non-sticking, so from one At the beginning, it entered the pit of the harvest, and it was not possible to manage it later.

Solution: When purchasing corn varieties, choose the variety that has been planted in the local area for a few years. The new variety is still cautiously tried. In addition, you need to ask for an invoice or receipt so as not to accept the account when there is a problem.

2, planting too dense

The rice plants are impervious to air and poorly ventilated, which may cause the differentiation of the ear of the corn to be hindered, resulting in poor development and further formation of a stick-free phenomenon.

Solution: How many pounds of corn per mu, the planting density is not the same, specific details, you can click on the bottom to learn more.

3, drought and water shortage

The period when corn is most in need of water is the big trumpet period. If it is dry and rainless during this period, and it will not be irrigated, it will greatly affect the extraction of tassels. In severe cases, the tassels will die, and the amount of pollen will be greatly reduced. It is normal for the corn to be out of shape.

Solution: If there is drought, timely irrigation, if there is no irrigation condition, it can be sprayed outside.

4, the flowering period is blocked

During the flowering period of corn, it encounters drought or even rainy weather, which affects the normal pollination of corn, can not complete the insemination, and eventually forms a phenomenon of no sticking.

Solution: If there is water in the rainy weather, drain it in time. If it continues to dry, you can refer to the solution at the previous point.

5, pest damage

Because pests and diseases lead to a large area of ​​non-sticking phenomenon is rare, unless it is the occurrence of extreme pests and diseases, usually a small area occurs, but every year everyone will control them, so the above four cases.

Solution: Corn borer, corn armyworm, big spot disease, small spot disease and other pests and diseases, good control, there are many medicines on the market, and the cost of one acre is not big, we should not prevent it because it saves trouble.

Finally, the agricultural knowledge network Xiaobian warm reminder: everyone must pay attention when buying seeds, not to buy corn seeds that are unclear for the sake of greed and cheap. In Xiaobian's view, the most important thing to grow crops is to hope for a good harvest. So the corn is not the same as the farmers' busy work, so the reason why the above corn is not good is hoped that the farmers will pay attention!
