近年来苏联农业科学院土库曼农业科学研究所培育出一种在棉花收获前能自然落叶的棉花新品种和一系列新品系。苏联自然落叶棉花新品种具有早期自然落叶的稳定遗传特性,即在收获之前2个月里棉叶就开始变红、变黄,到棉花成熟可以采收时,叶子已完全脱落的优势,这就为棉花机械采收开辟出一条新的途径。采用这一品种,可以用机械采棉代替人工拾花,减少劳动强度,缩短采棉时间,收获及时;棉花同时期落叶,加强了棉花成熟期的同步,霜前花增多,棉花质量和等级提高。
In recent years, the Soviet Union Academy of Agricultural Sciences Turkmen Institute of Agricultural Sciences to cultivate a kind of cotton before harvest can naturally leaves new cotton varieties and a series of new lines. The natural deciduous cotton varieties of the USSR have the stable genetic characteristics of early natural deciduous leaves, that is, the cotton leaves begin to turn red and yellow within 2 months before harvesting, and the leaves have the advantage of complete shedding when the cotton is mature and can be harvested Open up a new way for cotton mechanical harvesting. The use of this species, you can use mechanical pick cotton instead of manual pick-up, reduce labor intensity, shorten the time of picking cotton, harvest time; the same period of cotton leaves, strengthening the synchronization of cotton maturity, increased frost before the flower, cotton quality and grade .
