Control the growth of corn, prevent lodging and increase yield

Corn prosperity control should be an issue of concern to farmers in the near future. Corn boom control has a lot of benefits to corn, which will be introduced to you in detail below, but first of all, it must be scientific, otherwise it may be counterproductive.

Why should corn be controlled?

I believe many friends will ask this question. In fact, this is related to the growth of corn, and because the corn fertilization method commonly used by farmers is not very scientific. We all know that corn is a fertilizer-loving crop, which requires many times of topdressing during the growth period in order to increase the yield and quality of corn.

However, because people are busy and unable to do what they want in farming, they often adopt the planting method of sowing and fertilizing at the same time, which is what we often call the "one-shot" planting method, although this planting method saves the trouble of topdressing three times during corn growth. However, it also results in large growth fertility in the early stage of maize, which is easy to cause excessive growth or even overgrowth in the seedling stage.

According to the normal growth of corn, it does not need much fertilizer in the early stage. In the middle period of corn growth, the soil fertility gradually decreases, but this is the period when corn needs a large amount of fertilizer, so it is easy to cause poor growth, underdeveloped roots and lodging. Especially in the later stage, it will cause corn fruiting dissatisfaction and affect corn yield. However, if you choose controlled-release fertilizer with good fertility, these conditions can be alleviated to a certain extent.

In addition to the choice of slow-release fertilizer, the most important thing is to control prosperity correctly.

I think many friends can understand one or two things about the role of corn in controlling prosperity. Reasonable chemical control can have the effect of "upper control, lower promotion" to corn. Specifically, it is to control the overgrowth of corn. Corn is the best time to control growth when it grows from 8 to 10 leaves, that is, when the corn is about as high as the knee.

Because the weather is hot and rainy during this period of time, corn is very easy to grow. Timely spraying of prosperity control drugs can control the upward growth speed of corn, help corn straw thicken, and corn growth shows horizontal development. This can play a good role in preventing lodging of corn.

More importantly, the control of corn growth can make the root of corn grow better and the root grip more firmly. And the light transmittance between the corn is enhanced, and the ventilation is better, which helps the corn to bear fruit better and reduce the occurrence of corn protuberance.

The choice of time to control prosperity

However, the most important thing to control the prosperity of corn is the grasp of time, once something goes wrong, it will not only not have a good effect of controlling growth, but will affect the fruiting and lodging resistance of corn. The best time to control the growth of corn is when it grows from 8 leaves to 10 leaves. During this period of time, we should keep a tight grip on prosperity.

Controlling the growth of corn too early will affect the growth of corn and the straw will become shorter. Too late, that is, after the corn grows 12 leaves, it will cause the uneven growth of corn straw, the bottom straw is too long, the middle is too short, but the corn is easy to lodge. And in serious cases, the male ear differentiation of corn will fail, unable to disperse powder, which will affect the yield of corn.

The above comes from promoting agriculture through science.
