Popularizing Transgenic Insect Resistant Cotton In Xinjiang

Although transgenic insect resistant cotton seeds do not have the trouble of getting rid of insect pests, this kind of insect resistant cotton has no such effect. cotton It also resists insect pests while resisting insect pests, resulting in an increase in infertility rate in cotton seeds.

In August 11th, in the second session of Xinjiang Spin clothing At the technical forum, Yao Mu, a member of the Chinese Academy of engineering, said that last year, 47 cotton fields in the north and south of Xinjiang were investigated and found that the rate of infertility in cottonseed rose rapidly, reaching 12%, and no insect was used to pollinate cotton seeds.

According to reports, Xinjiang has been promoting genetically modified insect resistant cotton since 2012, and 90% of the cotton grown now is genetically modified insect resistant cotton, including the mainland. Transgenic cotton has been rapidly promoted. "The reason for the rapid promotion is that the transgenic insect resistant cotton produced is very high, and the Ministry of agriculture is making the output as the first reference element when approving the seed."

At present, the nationwide transgenic insect resistant cotton has been independently cultivated by China, while the previously planted non insect resistant cotton has only 1% sterility. "At the very beginning, the yield of transgenic insect resistant cotton is high, but now it appears that the yield of transgenic insect resistant cotton will decrease due to the increase of infertility rate, and the most important thing is the decline in fiber quality." Yao Mu said.

Yao Mu found that the cotton fiber of transgenic insect resistant cotton is getting shorter and thicker. The cotton grown out of the seed cause has become coarse cotton. On average, the fine cotton can produce 5000 to 7000 metric counts, and the long staple cotton produces more than 9000 metric tons. However, the transgenic insect resistant cotton can produce 4000 metric tons. Because the length of the cotton fiber is not enough, the high woven cotton becomes weaker.

To improve the competitiveness of Xinjiang's textile and garment industry, Yao Mu believed that the roots should be picked from planting: first, to cultivate new varieties; two, to set up standards for machine harvested cotton cultivation. "Now China's labor costs are getting higher and higher, and the labor force willing to pick cotton is also less and less. Therefore, popularizing machine picked cotton is inevitable, but now the maturity of cotton harvested in Xinjiang is not uniform. Some cotton mature transition, some cotton is not yet mature, which affects the quality of cotton and fiber. At the same time, when the machine is picking, a lot of impurities are imported into the machine, making the quality of cotton fiber more difficult to control.

Some machines even caught cotton poles and plastic films in cotton. "Once a business complained to me that a more than 200 kilogram cotton bag would hire 4 people to pick up impurities and 4 people to pick it up one day." Yao Mu said. It is precisely because of the impurities in cotton fibers that some enterprises are afraid to use domestic cotton and try their best to find imported cotton.

According to the introduction, the United States started planting machine harvested 40 years ago, and the lowest fruit branches of machine picked cotton should be 18 cm above the ground level. However, at present, the lowest cotton branch of the machine picked cotton planted in Xinjiang is only 10 centimeters from the ground, so that when the machine is picked, all the plastic films on the ground are caught. "Cotton branches are growing upside down. When picking cotton pickers, it is very easy for the graspers to grasp the branches. It is suggested that the cotton varieties with the growth of branches should be cultivated." Yao Mu said.
