1、 Cotton producing area

The origin of cotton is in subtropical areas, but it is cultivated in many areas. The main producing areas in the world are China, the United States, India, Egypt and Uzbekistan. Among them, China has the largest unit yield. The producing areas in China mainly include the Jianghuai plain, the North China Plain, the northwest of Shandong, the Jianghan Plain, the cotton area in southern Xinjiang, the Northern Henan plain and the coastal plain along the lower reaches of the Yangtze River. Among them, southern Xinjiang cotton region is the largest base for cotton growth. The region has less rain, sufficient light and dry climate all year round, which is suitable for the growth of cotton

2、 Cotton growth environment

1. Light conditions: cotton is a light loving crop, which is suitable for growing under sufficient light conditions. When cultivating, we must choose plots with sufficient light. The stronger the light, the more sufficient the cotton can grow better, which is conducive to the increase of yield

2. Water condition: cotton has certain drought tolerance, but it also needs water during growth. Different growth stages have different water demand. The water demand from sowing to seedling emergence is the largest

3. Soil conditions: the water and nutrients needed for cotton growth and development are obtained from the soil, which has certain requirements for the soil. The soil had better have sufficient fertility. Soil moisture, nutrients, temperature, air, salt content and texture all have a great impact on cotton growth
