Anhui Province Although it is a major cotton producing province in China, there are many problems in cotton production, such as insufficient reserves of technological innovation, low integration, and a variety of cotton varieties. The provincial cotton industry technology team, led by Lin Yi, a leading expert and professor of Anhui Agriculture University, has made certain breakthroughs in cotton breeding, supporting technology research and demonstration, and mechanized harvesting of cotton.

　　 Technical system of cotton industry In the Dongzhi, Wangjiang, Wuwei, Quanjiao and Taihu counties, 5 demonstration bases were established, and about 700000 new acres of new varieties and technologies were promoted. Experts from the cotton industry team carried out a variety comparison experiment in Dongzhi County, and screened out the cotton dominant varieties suitable for local cultivation. Among them, two varieties of Tsuen Yin cotton 2 and China Cotton Institute 66 exhibited demonstration area of 1200 mu.

The team has also worked with the seed industry companies in Anhui and Hunan and Hubei to promote the breeding of genetically modified insect resistant cotton, Anhui hybrid cotton 9, Wan Za cotton 11 and WAN Za Mian 10, and so on. 500 thousand cotton varieties have been bred by researchers in our province.

Because cotton grows much, Mechanization Low level, especially cotton harvesting cost accounted for 50% of the total cost. In the low cotton market today, farmers' planting benefit is very difficult to improve. Therefore, the mechanization of mechanized harvesting of cotton is the only direction and fundamental way to modernize cotton production.

Last year cotton harvest season, the cotton industry team experts in Wangyang County Huayang town machine cotton picking demonstration base, to achieve the mechanical harvesting of cotton, this is the first time in Anhui's history of cotton mechanized harvesting, marking the Anhui cotton mechanization planting technology research has made a major breakthrough.

According to Zheng Shufeng, an Associate Research Fellow of the Cotton Research Institute of the Provincial Academy of Agricultural Sciences, the net harvest rate of cotton harvesting in the demonstration area reaches 95%, and the impurity content is less than 8%. The recovery efficiency is high, and the labor saving rate is over 60%. The cost saving, labor saving and efficiency increase are remarkable, laying a good foundation for realizing the fundamental spanformation of cotton production mode in Anhui province.

The industrial system of the cotton industry technology system has been continuously improved. The no till planter has been screened and improved, and cotton pickers and other machinery have been introduced. The collection and creation of germplasm resources for machine harvested cotton, selection and breeding of machine picked cotton varieties, population control technology of machine picked cotton, chemical topping agent and chemical defoliation ripener have been studied.
