The latest growth environment of cotton

Cotton is a very special food in our life, is the main raw material of all kinds of textiles, and the planting area in our country is very large. Cotton is a necessity for us, so more and more people grow it. However, cotton can not be planted everywhere, because the growth of cotton has certain requirements on environmental conditions. Today, the editor has brought you the growing environment of cotton. Let's take a look at it.

1. Lighting

The growth of cotton has a great demand for light, so we must ensure that there is sufficient light when planting cotton. When the light time is long and the intensity is suitable, the cotton yield is high and the quality is good. If the light is not enough, it will not only reduce the yield and quality, but also have a great impact on the follow-up seed work. So when we plant cotton, we should choose the planting plot in a place with plenty of light. Then the light should be reasonably controlled according to the growth stage of cotton, so that the photosynthesis of cotton will be improved and the photosynthetic matter in the plant will be increased.

2. Moisture

Water is also an indispensable environmental condition for planting cotton, and the demand for water will change with the growth stage of cotton in the growth process. For a period of time before emergence, the soil water content should be kept at about 75%. The soil water content within the 40cm at the seedling stage should be kept at about 65%, and should be appropriately increased by 5% after entering the early bud stage. Then in the full flowering stage and boll opening period to maintain about 70%, a large part of the water consumption of cotton during growth is used for transpiration. Therefore, we must ensure that there are sufficient water sources around to meet the water needs of cotton growth.

3. Soil

Although the requirements of cotton on the soil are not very strict, but because the nutrients and water in the growth of cotton need to be obtained from the soil, and there is also a part of the air from the soil. Therefore, it is also necessary to ensure the quality of the soil, in the planting process, the physical and chemical properties of the soil directly affect the growth of cotton. It will have a great impact on the yield and quality. Therefore, when we choose soil, we should pay attention to comprehensive consideration from the aspects of moisture, temperature, PH value and so on, so as to create a good growth environment for cotton.

4. Heat

Heat also has a great effect on the growth of cotton. Especially in the early and later stages of cotton growth, it is the most sensitive to the change of heat. The emergence time of cotton after sowing generally takes 1-3 weeks, and the accumulated temperature at this time is about 300 degrees. When the temperature is about 20 degrees after sowing, seedlings can emerge in a week, and if the temperature is unstable, it may take about 3 weeks. In the later stage, heat will not only affect the yield, but also cause great harm to the quality of cotton, so we must pay more attention to it when planting.

The above is a brief introduction to the growing environment of cotton. The growth environment of cotton is very important and is closely related to planting benefits, so we must pay more attention to it when planting. That's all for today's introduction.
