The Yield Of New Machine Picked Cotton Varieties Bred By Xinjiang Exceeded 690Kg / Mu

According to Li Xueyuan, a researcher at the Institute of economic crops, Xinjiang Academy of Agricultural Sciences, the current cotton standard for processing high-grade veils is double-29 standard (that is, the cashmere length and fiber strength are more than 29). However, the biggest problem of machine picking cotton is that there are many impurities in the harvesting process. After two or three ginning, the length of cashmere will be lost, and the fiber strength and fineness are not high, resulting in the oversupply of medium and low fiber cotton. Over the years, the economic crop Research Institute of Xinjiang Academy of Agricultural Sciences, relying on the national cotton industry technology system, national key R & D, national natural fund and autonomous region key R & D projects, cooperated with cotton planting bases to develop a new early maturing, high-quality and high-yield machine picked cotton variety yuanmian 11. This new cotton variety can reach 31.6 mm in length. After ginning, it can still ensure the length and toughness of cotton, fully meet the requirements of high-end production enterprises for high-quality cotton, and lay a foundation for the development of high-end machine picked cotton in Xinjiang.

At the same time, taking the new machine picked cotton varieties as the core, the researchers also integrated and matched key technologies such as precise chemical molding control, chemical capping, efficient defoliation and ripening, and tip sealing control. "Through supporting technologies, labor costs and field management difficulties can be effectively reduced." Tian Xiaoli, a professor at China Agricultural University, said that in combination with Xinjiang's climate and environment and through continuous improvement of formula technology, the medicament can also be more suitable for UAVs, cotton pickers and other mechanical equipment.

Li Xueyuan said that the promotion of new varieties of machine picked cotton can solve the problem of picking cost, reducing the harvesting cost of a mu of land from 700 yuan by hand to 150 yuan by machine; through the genetic improvement of machine picked cotton varieties and the improvement of chemical control agents and defoliation and ripening agents, the net recovery rate and recovery rate of mechanical picking can be higher, and the waste of more than 30 kg per mu can be reduced, and the yield and agriculture can be improved accordingly People's income. With the cooperation of farmers, scientific research institutions and enterprises, a complete industrial chain of "cotton spinning enterprises + raw cotton processing enterprises + regional production cooperatives + farmers" can be gradually formed to help Xinjiang cotton develop with high quality.
