矮壮素是一种植物生长抑制剂，具有抑制植物伸长而不抑制细胞分裂的特性，能使植物节间变短，茎秆变粗，株形紧凑，叶色深绿，提高生理代谢活性，增强对不良环境的适应能力。试验表明，棉株对矮壮素的反应特别敏感，用矮壮素来控制棉花徒长，防止蕾铃脱落，效果十分显著。蕾铃 Chlormequat is a plant growth inhibitor, with inhibition of plant elongation without inhibiting the characteristics of cell division, can make plant internodes shorter, thicker stem, plant compact, dark green leaf color, improve the physiological and metabolic activity , To enhance the ability to adapt to the adverse environment. Tests show that cotton plants are particularly sensitive to the reaction of CCC, CCC to control the growth of cotton, to prevent the fall of bell, the effect is very significant. Bell
