Xinjiang Cotton Planting Patent Technology Won The Invention Gold Award Of "African Innovation Week"

?

Morocco's "African innovation week" was founded in 2016 with the support of the International Federation of inventors' associations and other institutions. The achievement of the invention gold award is supported by several patent technologies of the field Liwen team of the cotton cultivation group of the economic crop Research Institute of Xinjiang Academy of Agricultural Sciences, and the technology of the Chinese Academy of Agricultural Sciences, Huazhong Agricultural University and other units. As the first inventor, Tian Liwen was also awarded the honorary title of "innovation master" at the fifth "African innovation week" in Morocco.

According to Mao Shuchun, chief national cotton cultivation expert of Cotton Research Institute of Chinese Academy of Agricultural Sciences, the achievements of "innovation and application of key technology for high yield and high efficiency production of oasis cotton" have made breakthroughs in cotton seed breeding, sowing, water and fertilizer operation and harvesting, among which, the breakthrough of precision sowing and seedling protection technology is the most valuable. Because the seeds with cracks can not be removed effectively, the lower limit of germination rate of qualified cotton seeds is only 80%. To solve this world problem, Tian Liwen's team invented an efficient mechanical equipment for removing cracked seeds, combined with regional optimization of seed propagation and innovative technology of processing process, the seed germination rate was stable between 88.0% and 96.0%. These techniques have broken the situation that the precision sowing technology at home and abroad is mostly limited to mechanical design and ignores the high-quality seed production and agronomic technology supporting situation. They not only improve the germination rate, but also ensure that the seedling protection rate of cotton field reaches 85.1% to 92.2%, which is 10.5% higher than that of the surrounding control cotton field. "This has promoted the wide spread of the cotton precision sowing technology of" one hole, one grain "in Xinjiang, and effectively reduced the material and labor costs compared with the previous" one hole, multiple seeds "sowing method." Xinjiang Agricultural University doctoral supervisor Xu Wenxiu said.

In July this year, the team's patent achievement "key technology innovation and application of light, simple and efficient Xinjiang cotton industry" won the first prize of Xinjiang Uygur Autonomous Region Technological Invention Award. Up to now, the team has obtained 13 patents and 2 patents have been awarded "China Patent Excellence Award" by the State Intellectual Property Office.

Yu Shuxun, academician of the Chinese Academy of engineering, believes that in addition to the matching method of single seed precision sowing cotton field for seedling protection, the team's patented production method of organic long staple cotton raw materials for spinning combed 300 cotton yarn also has a breakthrough significance, so that the raw materials produced in Xinjiang can also spin combed 300 cotton yarns. In the past, long staple cotton used for spinning more than 300 combed cotton yarns was completely imported, and the development of high-end textiles was often "stuck" ”The problem.
