几种新型植物生长调节剂对棉花产量和品质的影响

Effects of Several New Types of Plant Growth Regulator on the Quality and Yield of Cotton

保棉丰、８９１、双效素和缩节胺４种植物生长调节剂型，使棉花产量较对照增产２９．６１％～１０．６１％；霜前产量较对照增加４９．９３％～６．０７％．其中以保棉丰增加棉花产量、提高棉花品质的作用最为明显．试验应用的几种植物生长调节剂型，对棉花叶面积系数、株型和生殖生长与营养生长均有不同程度的协调作用，并可增加棉花叶片叶绿素含量和比叶重．

In this experiment,the applications of the four plant growth regulatous-Bao Mian Feng, 891, Shuang Xiao Su and Suo Jie An-increased the yield of cotton by 29.61% ￣ 10.61% and the yield of cotton before frost by 49.93% ￣ 6.07%. Among the regulators,Bao Mian Feng was the most effective in increasing the yield of cotton and improving the quality of cotton. All of them also had regulatory functions to LAI,the shape of plant,growth and the contents of chlorophl etc.
