随着生产和社会经济的发展,纺织工业对棉花生产的要求日愈增高。在传统栽培方法的指导下,棉花基部烂铃、上部早衰成为制约棉花产量和品质提高的两大难题。早在1927年国外曾有人作过摘除棉花早花试验,可增产20%以上,但主要限于理论探讨,未能形成一项实用技术。在国内,60年代也曾有人做过打去下部两个果技的试验,由于当时尚未采用化控技术,增产不显著。1985年以来,我们采取多学科、多层次的协作,深入开展棉纤维发育生理、改善棉纤维
With the development of production and socio-economic development, the requirements of the textile industry for cotton production are getting higher and higher. Under the guidance of the traditional cultivation methods, the bad cotton bolls and the upper part of the cotton become the two major problems that restrict the yield and quality of cotton. As early as 1927, some people made cotton removal tests earlier than others, which could increase the yield by more than 20%. However, the main reason was limited to theoretical discussions and failed to form a practical technology. In the country, in the 1960s, some people tried to hit the lower part of the fruit-and-fruit test. Since the chemical control technology was not used at that time, the yield increase was not significant. Since 1985, we have taken a multidisciplinary and multi-level collaboration to further develop cotton fiber physiology and improve cotton fiber
