试验结果表明 :新型生长调节剂对棉花营养生长抑制作用小于助壮素 ,增加现蕾、提高结铃的效果优于助壮素。 5个新型调节剂对棉花均有明显的增产效果 ,增幅为 7.4%～ 17.3 %。其中以双效保蕾铃增产效果最高 ,增加产量为 2 43kg/hm2 ,增产幅度达 17.3 %。
The results showed that the new growth regulators had less inhibitory effect on the vegetative growth of cotton than menthralin, increased the budding and improved the boll-forming effect. Five new regulators have significantly increased cotton yield, an increase of 7.4% to 17.3%. Among them, the double-effect boll-bell bolting had the highest yield increase with an increase of yield of 2 43kg / hm2 and a yield increase of 17.3%.
