What is the cause of the excessive growth of cotton? Can spraying fertilizer be prevented?

Cotton production occupies a very important position in our country, because cotton is planted in many places in our country. In the process of planting cotton, growers will encounter a very headache phenomenon, that is, cotton will appear excessive growth in the field, which is also a key factor that will affect our cotton yield. What causes cotton to grow? Can fertilizer be prevented?

What causes cotton to grow?

1. The watering method is incorrect

Water is very important for cotton growth, because only when the water in the soil meets the growth needs of cotton can it grow smoothly. However, cotton at different growth stages has different requirements for water. Generally speaking, in the period of vigorous growth, the water content in the soil needs to be about sixty or seventy percent. If the watering times are not controlled well, there will be excessive growth.

2. Use too much nitrogen fertilizer

Cotton needs a lot of fertilizer when growing, but you can't use a lot of nitrogen fertilizer at every stage, because the demand for nitrogen fertilizer is different at different growth stages. Generally speaking, the demand for nitrogen fertilizer is relatively large at the early stage of growth, and the demand for potassium fertilizer is relatively small. At the later stage of growth, the demand for nitrogen fertilizer is relatively small, and the demand for phosphorus and potassium fertilizer is larger. If large amounts of nitrogen fertilizer are used for a long time, it will cause cotton to grow excessively.

3, planting density is too dense

If cotton is planted too close to each other, it will not get enough light, so the photosynthesis of cotton will be reduced, and the synthetic nutrients will also be reduced, so there will be excessive growth.

Can fertilizer spray prevent cotton from growing too long?

Spraying fertilizer, then to master a certain skill is to prevent excessive growth of cotton, if it is late growth, it is generally recommended to use a variety of fertilizers, rather than using a large number of single nitrogen fertilizer, need to be used together with phosphorus and potassium fertilizer. After using fertilizer, cooperate with pruning work, so as to effectively prevent the phenomenon of excessive growth of cotton.

In addition to spraying fertilizer, control moisture. Generally, watering should not be too much or too little. If it is in drought for a long time and the temperature is high, irrigation should be strengthened. If it is in flood, rainy season water more time to drain, so as to avoid the phenomenon of water rot roots.

At ordinary times, we should also prune the redundant branches and leaves under the main stem in time, so that the nutrient absorption of the whole cotton root system will be reduced, and naturally there will be no excessive growth phenomenon.

Weeding in the field should also be done in place, so as to reduce the absorption rate of nutrients by the roots. If there is a serious excessive growth, the roots around the cotton plant can be cut into segments.
