矮壮素是一种人工合成的植物生长调节剂,它具有抑制植物细胞伸长而不妨碍细胞分裂的特殊功能。对棉花施用后,能使株型紧凑,防止疯长,推迟封行,改善通风透光条件,增强光合作用,减少蕾铃脱落,促进早结桃和多结桃,一般可增产10%以上。棉花施用矮壮素必须严格把握以下几点:1.确定对象田需要矮壮素控制的,主要是水肥条件较好,特别是高水肥的棉田。这些棉田在6月上旬到7月中旬的蕾期和初花期,因水肥充足而生长过旺,不及时控制,会引起疯长,使棉株秆高、枝长、节稀、叶大,过早封行,导致棉田荫蔽,造成中下部蕾铃 Chlormequat is a synthetic plant growth regulator that has the specific function of inhibiting plant cell elongation without interfering with cell division. After the cotton is applied, it can make the plant compact, preventing soaring, postponing the sealing, improving the ventilation and light conditions, enhancing the photosynthesis, reducing the falling off of the buds, promoting the early peach and the multi-peach blossom, generally yielding more than 10%. The application of CCC to cotton must be strictly controlled by the following points: 1. The target field needs to be controlled by CCC, which is mainly due to better water and fertilizer conditions, especially high water and fertilizer. These cotton fields in early June to mid-July the budding and early flowering, due to adequate growth and over-fertilization of water and fertilizer, not controlled in time, can cause insane, cotton stalk height, branch length, thin, big leaves, premature The closure line, leading to cotton shade, resulting in the lower part of the bell
