Key Technical points of Cotton Seedling Management

Cotton is a very important crop all over the world. Cotton is the main raw material of quilts, cotton-padded clothes and other necessities of life. Among them, China has a very wide planting area, and China is also one of the main cotton exporting countries. However, many do not know how to manage when planting, resulting in planting failure, in fact, cotton seedling management is very important. Then let's take a look at the management technical points of cotton seedling stage together with Xiaobian!

1. Guarantee the whole seedling

After the emergence of cotton seedlings, the growth of seedlings should be observed regularly, and the healthy seedlings with the same growth should be supplemented in time if there is a lack of seedlings. The seedlings should be transplanted as early as possible, because if the seedlings are transplanted early, the time for slow seedlings will be shortened and the growth recovery of seedlings will be accelerated. If there is no prepared seedling, but when the lack of seedlings is serious, then it is necessary to sow in time, and the sowing time should be properly sparse to avoid affecting the germination of seeds.

2. Prevent large and small seedlings

The size of seedlings is a problem that many friends often have when planting. The growth rate of seedlings is different, and there is a phenomenon that big seedlings bully young seedlings, resulting in poor nutrition for young seedlings. Therefore, when we apply fertilizer, we should adjust the dosage according to the size of seedlings, use eccentric fertilizer for seedlings, promote the growth of seedlings, improve nutrient absorption capacity, and prevent large seedlings. Promote cotton seedlings to form good colony growth structure.

3. Cultivate and loosen soil

Intertillage is very important to loosen the soil. Intertillage prevents soil hardening, reduces soil moisture and reduces the incidence of pests and diseases. Raise the temperature of the soil, promote the growth and development of seedlings, and cultivate once every time after rain to improve the permeability of the soil and ensure that the soil is soft and deep. Promote root growth, expand roots, enhance root nutrient and water absorption capacity. The cultivation depth shall not exceed 10 cm, and no more cultivation shall be allowed to ensure that there are no weeds and the soil is soft.

4. Disease control

Because of the weak nutrient absorption ability of seedlings and underdeveloped roots in early seedling stage, seedlings are easily infected with germs in rainy weather. It leads to the decline of seedling growth ability, weakening of growth, and in severe cases, it will lead to dead seedlings. Therefore, we must do a good job in disease control, among which the longest occurrence of anthracnose, blight and so on. To prevent the main, in the temperature fluctuations too large to spray seedlings in time to improve the resistance of seedlings, regular observation of seedlings, so that diseases early detection and early treatment.

5. Eliminate pests

In addition to the serious damage of diseases in the seedling stage, the threat of pests is also very large, and the variety of pests, different damage sites, control work will be affected to some extent. Pest pests not only hinder the growth of cotton seedlings, but also carry germs to spread diseases, causing plants to lose their growth points and fail to bear fruit. Therefore, we should use the corresponding chemicals to prevent it and avoid unnecessary losses.

The above is a brief introduction to the key points of cotton seedling management technology, cotton growth ability is relatively strong, yield is also relatively high. However, if the seedling stage is not well managed, it will easily affect the growth of cotton, so we must do a good job in the seedling stage to ensure their own economic benefits.
