In the process of cotton planting, natural cross-pollination leads to serious seed variation and degradation. After entering the 1980s, China Cotton Research Institute finally developed a series of new cotton varieties. Farmers spend money to buy coated cotton seeds every year, and the output is stable at 500 kg -600 kg/mu of seed cotton. Therefore, cotton yield has a great relationship with seed quality. China cotton is divided into three major producing areas, namely the Yellow River Basin, the Yangtze River Basin and Xinjiang. The sowing period in the Yellow River Basin and the Yangtze River Basin is March-April, and that in Xinjiang is April-May. The harvest season is like this: the Yangtze River basin is from late July to early September, the Yellow River basin is from early July to early August, and Xinjiang is from mid-July to early September.

Introduce advanced irrigation technology. Under-film atmospheric pressure drip irrigation can effectively save water charges, improve land utilization rate, save labor and time, reduce labor intensity, enhance the ability to resist natural disasters, and greatly increase cotton yield. Diseases, insects and weeds should be strictly controlled at harvest time, only in this way can cotton yield and quality be high! In a word, only by taking comprehensive measures can we ensure that cotton seedlings are neat, Miao Zhuang, develop early, grow steadily and not premature. Only by avoiding diseases, insects, weeds and natural disasters can we ensure high yield and high quality of cotton!

Adopting the planting mode of moderate density and paying attention to the management of fertilizer and water, since 2005, the high-yield cultivation technology of 1,000 kg cotton summarized by Chu Xinge has achieved great success in the Yangtze River basin, forming a double-kg cultivation mode with a yield of 1,000 plants per mu, which has enabled some farmers to obtain a high-yield mode with an actual yield of more than 65,438+10,000 kg per mu. Therefore, cotton yield has become the most concerned issue for cotton farmers. In the process of cotton planting, there are many factors that affect cotton yield. Only by understanding the reasons and taking corresponding measures can we ensure the healthy growth of cotton trees, produce more cotton and make cotton have a good yield.

Cotton needs different amounts of nitrogen, phosphorus and potassium at different growth stages. Therefore, cotton growers should apply fertilizer scientifically in strict accordance with the demand for fertilizer in different growth stages of cotton.
