The weak growth of maize seedlings and lack of timely remediation are likely to affect maize yield.

The rising trend of corn is weak, how to remedy it? With regard to this problem, we must first find out the reasons for the weak growth of corn, otherwise, it will be difficult to solve the problem. Now corn is still in the seedling stage, and the growth of the seedling stage is weak, which is not conducive to the formation of maize yield.

For example, the northeast region is dry at the seedling stage this year, and its growth is understandable. After all, the emergence of local corn seedlings has been affected a lot. However, in the Huang-Huai region, Rain Water is relatively abundant in the seedling stage, which may not be lack of soil moisture, but whether it is lack of fertilizer or soil moisture, or improper field management, it is necessary to deal with it properly.

Shovel early and go early to promote development.

For corn shoveling as soon as possible, ploughing and weeding, especially for replanting or seedling replenishment, special attention should be paid to deep loosening in ridges and furrows after emergence, so as to seize accumulated temperature, loosen soil, resist drought and preserve soil moisture, and enhance maize root vitality. speed up the process of growth and development. This is also a major measure to improve weak seedlings at seedling stage.

Strengthen the field management and topdressing at the right time.

Drainage should also be carried out in time for the stagnant water in the field, and at the same time, after the stagnant water is discharged, the stagnant soil should be loosened to accelerate the dissipation of soil moisture. If the seedling stage is weak due to excessive drought, it should also be irrigated in time to replenish soil moisture. At the same time, it is necessary to eradicate and clean up weeds in the field in time to avoid competing with corn for soil moisture.

If the growth is weak due to lack of nutrition at the seedling stage, such as etiolation, leaf spots or diseases, it is necessary to apply medicine or fertilization in time. In order to supplement nutrition and promote development, timely fertilization should be applied to improve the stress resistance of plant growth.

It is worth noting that topdressing is neither too early nor too late. If topdressing is too early, the utilization rate of fertilizer can not be maximized, and if topdressing is too late, it will be green and mature late.

Weeding in time to control grass damage.

Generally, there are herbicides after corn planting, and the weed damage in the seedling stage is relatively mild, but if there are weeds in the corn 5-leaf period, you can choose the corresponding herbicides to weed again, especially some stubborn weeds.

Finally, I would like to remind farmers that they must pay attention to the prevention and control of diseases and insect pests in the field. Proper field management can greatly reduce the damage in the field and cultivate strong seedlings at the same time.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
