摘　　要：为给园林绿化提供株体矮小的毛竹,扩大毛竹新用途,进行了以清水为对照,竹笋期注射0.5%、1.0%、2.0%矮壮素矮化毛竹试验,结果为矮壮素可降低竹笋期生长量、株体高度、枝下高,其中与对照相比,只有2%浓度效果差异显著,株体高度可降低28.1%,枝下高降低30.3%;注射2%矮壮素可达到降低毛竹高度的目的,建议生产中推广应用。To provide dwarfing plants of Phyllostachys edulis,growing bamboo shoots were injected with Chlormequat chloride with concentrations at 0.5%,1.0%and 2.0%,respectively,pure water injection as CK.The result showed that Chlormequat chloride had an inhibiting effect on the heights of the whole bamboo,as well as on the clear bole height.2%Chlormequat chloride produced significant effect in comparison with CK,the height of bamboo can be reduced by 28.1%and clear bole height reduced by 30.3%.In conclusion,2%Chlormequat chloride solution exerts an obvious effect on inhibiting the growth and the heights of phyllostachys.
