棉花枯黄萎病,在我省发展很快,1971年全省仅有29.4万亩,1977年已蔓延到73.1万亩。轻的减产,重的绝收,有的地块甚至不能再种棉花。已成为我省发展棉花生产的严重障碍。通过几年来的研究,针对发病和传播的特点,我们认为防治棉花枯、黄萎病的策略应该是:“保护无病区,消灭零星病区,压缩轻病区,改造重病区。”根据病情,
Verticillium wilt in cotton was rapidly developed in our province. In 1971, the province only had 294,000 mu and it spread to 731,000 mu in 1977. Light cut production, heavy harvest, and some even can not plant cotton plots. Has become a serious obstacle to the development of cotton production in our province. Through several years of research, according to the characteristics of disease occurrence and transmission, we think that the strategy of combating cotton blight and verticillium wilt should be: “Protect the disease-free areas, eliminate the sporadic disease areas, compress the light area and transform the heavily wounded areas.” According to the condition ,
