The main points of the latest course of Cotton Seedling Management techniques and methods

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

1. Guarantee the whole seedling

After the emergence of cotton seedlings, the growth of cotton seedlings should be observed regularly, and it is found that where there are missing seedlings, healthy seedlings with the same growth should be made up in time. Transfer seedlings as early as possible, because if the seedlings are moved early, the slow seedling time will also be shortened, and the growth recovery of seedlings will be accelerated. If there are no prepared seedlings, but when the shortage of seedlings is serious, then sow in time and sow sparsely when sowing, so as to avoid affecting the germination of seeds.

2. Prevent large and small seedlings

Large and small seedlings is a problem that often occurs when many friends are planting. The growth rate of seedlings varies, resulting in the phenomenon that big seedlings bully small seedlings and lead to malnourished seedlings. Therefore, when applying fertilizer, we should adjust the dosage according to the size of the seedlings, use eccentric fertilizer for the seedlings, promote the growth of the seedlings, improve the nutrient absorption capacity, and prevent the large seedlings. Promote cotton seedlings to form a good population growth structure.

3. Ploughing and loosening the soil

It is very important to loosen the soil by ploughing, which can prevent soil consolidation, reduce soil moisture and reduce the incidence of diseases and insect pests. To improve the temperature of the soil and promote the growth and development of seedlings, the soil should be ploughed once after each rain to improve the permeability of the soil and ensure that the soil is soft and deep. Promote root growth, expand root system, enhance root nutrition and water absorption capacity. The depth of mid-tillage should not exceed 10 cm, and no more ploughing should be allowed to ensure that there are no weeds and soft soil.

4. Disease control

In the early seedling stage, because the nutrient absorption capacity of the seedlings is weak and the roots are not developed, so when it is rainy, the seedlings are very easy to be infected with germs. It leads to the decline of seedling growth ability, weakening growth, and in serious cases, it will lead to the death of seedlings. Therefore, we should do a good job in the prevention and control of diseases, of which the longest occurrence is anthrax, blight and so on. Give priority to prevention, when the temperature fluctuation is too large, we should spray seedling strengthening agent in time to improve the resistance of seedlings, regularly observe seedlings, so that diseases can be detected and treated early.

5. Eliminate pests

In the seedling stage, in addition to the serious damage of diseases, the threat of pests is also very large, and there are many kinds of insect pests, the harm position is different, the control work will be affected to a certain extent. Pests will not only hinder the growth of cotton seedlings, some will also carry bacteria to spread diseases, resulting in the loss of plant growth point, unable to blossom and bear fruit. Therefore, we should use the corresponding agents to prevent and control them to avoid unnecessary losses.

The above is a brief introduction of the key points of cotton seedling management technology, the growth ability of cotton is relatively strong, the yield is also relatively high. However, poor management at the seedling stage will easily affect the growth of cotton, so we must do a good job in the seedling management to ensure their own economic benefits of planting.
