多效唑是一种高效、广谱植物生长延缓剂,能延缓作物生长,抑制茎叶伸长,有利于分枝分蘖,增强作物抗逆性和抗倒伏能力。为探讨多效唑在花生上的增产效果及使用方法,我们进行了试验,结果如下: 喷药17天后矮化作用即明显表现出来,随浓度增加矮化程度增大。45天后调查,喷150、200、250、300ppm多效唑的花生,主茎分别比对照矮 Paclobutrazol is an efficient and broad-spectrum plant growth retarding agent, which can delay the growth of crops, inhibit the elongation of stems and leaves, facilitate the tillering of branches and enhance the stress resistance and lodging resistance of crops. To explore the effect of paclobutrazol on peanut yield increase and its application, we conducted the experiment. The results were as follows: The dwarfing effect was obvious after spraying for 17 days, and dwarfing increased with increasing concentration. 45 days after the investigation, spray 150,200,250,300 ppm paclobutrazol peanut, the main stem shorter than the control
