What about cotton late maturity?

Cotton planting is very common in our country, when planting cotton, if we want to have high yield and high quality, then we need to manage it carefully. If it is not properly managed, there will be many problems affecting the growth of cotton in the growth process. And greedy green late ripening is one of them, so what is cotton greedy green late ripening? What are we going to do? The following editor will give you a brief introduction, let's have a look!

1. What is greedy green and late ripening

In normal planting, cotton in September every year, the leaf color is still very thick green, green bolls are rare and not much boll, axillary buds are still growing, this represents that the cotton is green and late ripening. In the growth of cotton, if the early and medium-term management is improper or affected by the weather, environment and other factors. Then in the cotton flower and boll stage or bud stage, a large number of buds and bolls will fall off, resulting in a serious decline in the number of flowers and bolls. However, there is no place for the nutrition that should be provided for fruit growth, and it can only be supplied for vegetative growth, resulting in the continuous emergence of new shoots and axillary buds in cotton plants.

2. The reason for greedy green and late ripening

Some cotton varieties originally have the characteristic of late ripening, which is prone to the phenomenon of greedy green and late ripening. When planting cotton, if the sowing time is too late, it is also easy to delay the ripening time of cotton plants, which is also the main reason for the late ripening of cotton. Or when the temperature drops after autumn, a large amount of nitrogen fertilizer is applied in the cotton flower and boll stage, or there is a long-term lack of water in the well-nourished cotton fields, and continuous rainfall occurs in the late growth period, it may lead to the late ripening of cotton.

3. prevention and control measures

After the cotton enters the later stage of growth, the watering amount should be controlled according to the weather changes and the growth of cotton. If there are signs of premature senility, then appropriate drip irrigation, delay the water cut-off time, and apply the right amount of fertilizer. Promote the growth of cotton roots and enhance the growth ability of leaves, so as to improve the boll formation rate in the middle and upper part of the plant. For Wangchang Tian Laishu, it is necessary to control the vegetative growth, mainly to promote the reproductive growth of cotton, to provide air circulation, to avoid airtight leading to falling flowers and bolls. In addition, we should also do a good job in the classified management of early decaying fields and prosperous growing fields, so as to promote plant early maturity, pest control and so on.

4. Preventive measures

In order to prevent the phenomenon of greedy green and late ripening of cotton, we should give priority to prevention. In addition to choosing a high-yield and high-quality quality when planting, we must pay attention to controlling the sowing time. Avoid sowing too late leading to too much fertilizer and water in the later stage, and the application time is too late. Then, for the cotton plants with excessive growth and poor permeability in the later growth stage, the empty branches and old leaves should be cleared in time. Improve the permeability of cotton fields so that cotton bolls can mature prematurely as soon as possible.

The above is a brief introduction to the greedy green and late ripening of cotton. That's all for today's introduction. This article is for reference only. I hope it can help you all.
