植物生长调节剂助长素(1,1-二甲基哌啶氯化物),又名DPC、调节啶、壮棉素、甲哌啶、缩节胺。主要效应是抑制植株体内赤霉素的合成,从而抑制细胞伸长。我们在苏州市郊民主葡萄园使用40％助壮素水剂(江苏省激素研究所生产),浓度80ppm(即2ml加水10kg)与0.2％磷酸二氢钾混合,在巨峰葡萄花前5～7天,新梢生长展叶6～8片时,全株喷洒。助壮素对巨峰葡萄内吸传导活性较强,起多种调节生长的效应。经3～6天开始有明显的抑制植株营养生长,增加钙离子吸收,防止
Plant Growth Regulator Caulitin (1,1-dimethylpiperidine chloride), also known as DPC, regulatory pyridine, Supramurenumab, mepivacaine, shrink amine. The main effect is to inhibit plant gibberellin synthesis, thereby inhibiting cell elongation. We use 40% mepiquat chloride (produced by Jiangsu Hormone Research Institute) at the democratic vineyard in the suburbs of Suzhou, mixed with 0.2% potassium dihydrogen phosphate at a concentration of 80ppm (ie, 2ml of water and 10kg), 5 to 7 days before Kyoho grape , Shoot growth leaves 6 to 8, the whole plant spraying. Imidacloprid grape Juveniles on the strong absorption and conduction, played a variety of regulatory growth effect. After 3 ~ 6 days began to significantly inhibit vegetative growth, increase calcium absorption, to prevent
