棉花初花期每亩喷施助壮素10ml,对水40kg,对果枝果节均有不同程度的控制作用。一般对下部果枝果节影响小,而对上部果枝果节影响大,1～4果枝长度比对照缩短22.1％～47.3％,1～3果枝的果节和4～6果枝的1、2果节,7～9果枝的第一果节长度为对照的81.2％～99.4％,其余果节长度为对照的28.6％～67.2％。据1990～1991年8月20日多点调查,喷施助壮素的棉田,单株成铃比对照增加1.2个,花蕾多1.4个,脱落率减少8.6％。从结铃部位上看,喷施助壮素的棉株下部成铃率为52.2％,比对照增加14.4％;中部成铃
First flowering of cotton per acre Zhuangpi sprayed 10ml, 40kg of water, fruit and fruit sections have different degrees of control. Generally, the effect on the lower fruiting branches is small, but the effect on the upper fruiting branches is large. The length of 1 ~ 4 fruit branches is shortened by 22.1% ~ 47.3% compared with the control, 1 ~ 3 fruit branches and 1 ~ 4 fruit branches. , The length of the first fruit node of fruit branches from 7 to 9 was 81.2% ~ 99.4% of the control, and the length of other fruit segments was 28.6% ~ 67.2% of the control. According to the survey conducted on August 20, 1990 to August 20, 1991, the number of bolls per plant increased by 1.2, the number of flower buds increased by 1.4, and the rate of shedding decreased by 8.6%. From the point of view of the bolls, the percentage of bolls in the lower part of cotton plants sprayed with mepiquat chloride was 52.2%, increased by 14.4% compared with the control;
