盛成发等(1983)在研究棉铃虫经济阈值时指出,人工摘除部分早蕾可以提高棉花产量。欧阳显悦(1983)研究表明,在6月中旬对初花期的棉株喷植物生长调节剂,可提高棉花产量。我们在以上试验启发下,于1986~1988年在天门市棉区应用植物生长调节剂进行了除去棉株早蕾的试验示范,取得较好效果。试验示范结果表明,化学去蕾可以代替人工摘蕾,并大大减轻了红铃虫为害
Sheng Cheng et al (1983) in the study of the economic threshold of cotton bollworm pointed out that the artificial removal of some early bud can increase cotton production. Ouyang Xian Yue (1983) studies have shown that in mid-June for early flowering cotton plant growth regulators, can increase cotton production. Inspired by the above experiments, we carried out the experimental demonstration of removing premature buds of cotton plants from 1986 to 1988 in Tianmen cotton area using plant growth regulators, and achieved good results. Experimental demonstration results show that chemical removal of buds can replace the artificial extraction of buds, and greatly reduce the pink bollworm damage
