棉花化学控制技术是通过应用植物生长调节剂来调节生长发育的一种技术。北京农业大学结合我国棉花生产的特点和问题,研究成功了两项棉花化学控制新技术。一、棉花应用乙烯利催熟技术这项科研成果在1980年被评为农牧渔业部技术改进二等奖,1982年又被国家科委、农委评为重大科技成果推广奖。乙烯利催熟技术,主要是解决棉花晚熟问题,它的有效成分是,2—氯乙基磷酸,用它喷晚熟的棉田,可被棉叶、铃吸收、使棉铃体内乙烯(是一种调节果实成熟的激素)增加,可以使棉铃提早开裂7—10天,霜前花增加20%左右,品级提高一级,皮棉单产增加4—11%,每亩可增加经济收益15元左右,并为及时种麦、种油菜创造了条件,所以这项技术适应于南
Cotton chemical control technology is a technique that regulates growth through the use of plant growth regulators. Beijing University of Agriculture combined with the characteristics and problems of cotton production in China, the successful study of two cotton chemical control of new technologies. First, the application of ethephon cotton ripening technology The scientific research achievements in 1980 was named the Ministry of Agriculture, Animal Husbandry and Fisheries Technology Improvement Award, in 1982 by the State Science and Technology Commission, Agricultural Committee as a major scientific and technological achievements promotion award. Ethephon ripening technology, mainly to solve the problem of late maturity of cotton, which is the active ingredient, 2-chloroethyl phosphate, spray it late with cotton fields, cotton leaves can be absorbed, so that bolls of ethylene (which is a regulation Fruit mature hormone) increase, you can make cotton bolls early cracking 7-10 days, frost before the flower increased by 20%, grade to improve a lint yield increased 4-11% per acre can increase the economic benefits of 15 yuan, and is Timely wheat, rapeseed has created the conditions, so this technology adapted to the South
