What are the growth environment requirements for cotton?
Cotton is a very special crop in our lives and the main raw material for various textiles, and its planting area in our country is very large. Cotton is a necessity for us, so more and more people are growing it. However, not every place can grow cotton, because cotton has certain requirements for environmental conditions. Today, the editor brings you the growth environment of cotton. Let's take a look below!
1. Light
Cotton has a very high demand for light during growth, and when planting cotton, you must ensure there is sufficient light. When the light duration is long and the intensity is suitable, cotton yields are high and quality is good. If there is insufficient light, it will not only reduce yield and quality, but also have a great impact on subsequent seed-saving work. So when planting cotton, we should choose a planting plot in a place with sufficient light. Then, we should reasonably control light according to the growth stages of cotton, so that cotton photosynthesis will also improve and the photosynthetic substances in the plant will increase.
2. Moisture
Moisture is also an indispensable environmental condition for growing cotton. During the growth process, cotton's demand for moisture changes with the growth stage. During the period before emergence, the soil moisture content should be maintained at about 75%. During the seedling stage, the soil moisture content within 40cm should be maintained at about 65%, and after entering the early bud stage, it should be appropriately increased by 5%. Then, during the full flowering stage and the boll-opening stage, it should be maintained at about 70%. A large part of the water consumed by cotton during growth is used for transpiration. Therefore, everyone must ensure there is sufficient water around to meet cotton's moisture needs for growth.
3. Soil
Although cotton is not very strict about soil requirements, since cotton needs to obtain nutrients and moisture from the soil during growth, and part of the air also needs to be obtained from the soil, the quality of the soil must also be ensured. During the planting process, the physical and chemical properties and attributes of the soil directly affect the growth of cotton, and will have a great impact on yield and quality. So when choosing soil, we should pay attention to comprehensive consideration from various aspects such as moisture, temperature, and PH value, to create a good growing environment for cotton.
4. Heat
Heat also has a relatively large impact on the growth of cotton. Especially in the early and late stages of cotton growth, it is most sensitive to changes in heat. After sowing, cotton generally needs 1-3 weeks to emerge, and the accumulated temperature required at this time is about 300 degrees. When the temperature after sowing is about 20 degrees, it can emerge in one week. If the temperature is unstable, then it may take about 3 weeks. In the later stage, heat will not only affect yield, but also cause considerable harm to the quality of cotton, so everyone must pay much attention when planting.
The above is a brief introduction to the growth environment of cotton. The growth environment of cotton is very important and is closely related to planting benefits, so everyone must pay much attention when planting. That's all for today's introduction.
