花生开花后25～30天,每亩用15％多效唑粉剂40～50克,加水75千克,用背负式喷雾器均匀喷施,能显著地延缓植株仰长生长,使主茎高度降低,侧枝长度缩短,从而有效地控制旺盛的营养生长,增强植株的抗倒能力,保持较好的群体结构。同时,增加有效分枝,控制无效果针,促进荚果发育,增加饱果数和果重。开花后30天亩施50克多效唑的主茎高度降低14.9％,侧枝长度缩短16.6％,倒伏面积减少85％;单株有效分枝增加0.5个,单株饱果数增加7.9％,百果重增加5.2克,比对照增产花生果30.2千克/亩,净增产值43.3元/亩,投入与产出比约为1:21。
Peanut 25 to 30 days after flowering, with 15% per acre powder 38 to 50 grams, 75 kg of water, spray with a knapsack spray evenly, can significantly delay plant Yang Yang growth, the main stem height is reduced, shortened collateral length , So as to effectively control the vigorous vegetative growth, increase the lodging resistance of plants and maintain a better population structure. At the same time, increase effective branches, control ineffective needles, promote pod development, increase the full fruit number and fruit weight. After 30 days of flowering, the height of main stem of 50 g moxibustion was reduced by 14.9%, the length of collateral was shortened by 16.6% and the lodging area was decreased by 85%. The effective branch of single plant increased by 0.5, the number of fruit per plant increased by 7.9% Increase 5.2 grams, 30.2 kg / mu peanut than the control yield, net output value of 43.3 yuan / mu, input and output ratio of about 1:21.
