棉田适时适量施用矮壮素能使棉花增产。特别是生长旺盛的棉田更是如此,已由许多地区的试验所证实。但大面积飞机喷洒矮壮素对棉花的增产效应尚乏试验资料。为此,我们在兵团一二九团三连选了两块长势较好的棉田,参照地面施用情况,分两次以矮壮素的不同浓度 Appropriate amount of cotton plant Shuanghuan Su cotton can increase production. This is especially true for cotton fields that have been thriving, as evidenced by trials in many regions. However, there is still no experimental data on the effects of large-scale aircraft spraying CCC on cotton yield. To this end, we selected one or two regiments in the Corps regiment of three growing cotton fields better, with reference to the ground application, divided into two different concentrations of CC
