A Detailed and Up-to-Date Guide to Cotton's Growing Environment Conditions
Cotton is a very special crop in our lives and the main raw material for all kinds of 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. But not every place can grow cotton, because cotton has certain requirements for its growing environment conditions. Today, the editor has brought you the growing 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 the quality is good. If there is insufficient light, it will not only reduce yield and quality, but also have a great impact on the subsequent seed-saving work. So when we plant cotton, we should choose the planting plot in a place with sufficient light. Then we should reasonably control the 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. Water
Water is also an indispensable environmental condition for growing cotton. During growth, cotton's demand for water changes with its growth stages. 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. So everyone must ensure there is sufficient water around to meet cotton's water needs for growth.
3. Soil
Although cotton's requirements for soil are not very strict, since cotton needs to obtain nutrients and water from the soil during growth, and part of the air also has to be obtained from the soil, the quality of the soil must also be ensured. During the planting process, the soil's physical and chemical properties, attributes, and so on all directly affect cotton's growth. They will also have a great impact on yield and quality. So when choosing soil, we should pay attention to comprehensively considering 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 cotton's growth. Especially in the early and late stages of cotton growth, it is most sensitive to changes in heat. The emergence time of cotton after sowing generally takes 1-3 weeks, and the accumulated temperature required at this time is about 300 degrees. When the temperature after sowing is about 20 degrees, emergence can occur 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 no small harm to cotton's quality, so everyone must pay a lot of attention when planting.
The above is a brief introduction to cotton's growing environment. Cotton's growing environment is very important and is closely related to planting benefits, so everyone must pay a lot of attention when planting. That is all for today's introduction.
