近几年人们在棉花生产实践中,发现被二代棉铃虫咬掉部分早期花蕾的棉株,表现株高叶茂,铃大、铃多,有明显的增产优势.同时也参考了外地有关受二代棉铃虫为害而表现增产的报道,以此为思路,于1986年进行了棉花摘蕾试验. In recent years, people practiced cotton production practice and found that some of the early buds were bitten by cotton bollworms of the second generation of cotton plants, showing high leafy plants, bolls, bell more obvious advantages in yield increase .Also refer to the field by the second generation Bollworm harm and performance increase yield reports, as a train of thought, carried out in 1986 cotton buds test.
