我县每年有5万多亩棉花在生长中期出现旺长,使棉花蕾铃严重脱落达70%以上,形成高、大、空。有的株高一米七、八,下部六、七个果枝的蕾铃脱落或烂掉,群众叫做“麻田”、“竹田”,这就严重地影响着棉花的增产增收。在多年的生产中采用“深中耕”、喷“矮壮素”等防狂方法,均不很奏效。从 Every year, more than 50,000 mu of cotton in my county flourish in mid-growth so that the buds of cotton buds will fall off seriously by more than 70%, forming high, large and empty. Some plant height of one meter seven, eight, the lower part of the six or seven branches of the buds fall off or rotten, the masses called “Ma Tian”, “Takeda” This will seriously affect the cotton yield increase. In many years of production using “deep plowing”, spray “CC” and other anti-mad methods are not very effective. From
