摘要
选择4种不同立地条件的绿竹林分:人工抚育的山地竹林(A)、人工抚育的农用地竹林(B)、人工抚育的河岸地竹林(C)、未经抚育的河岸地竹林(D),研究了立地条件对绿竹蔸系结构的影响。结果表明:立地条件对竹蔸蔸幅有显著影响;立地条件对竹蔸数量的影响大小顺序表现为D>A>B>C,其中立地条件B最有利于产笋;人工经营措施有利于竹蔸长度的增加,从而有利于增加笋产量。研究结果可为绿竹林的科学管理提供依据。
The effect of site conditions on the stump structure ofDendrocalamopsis oldhami was studied on the stands under 4 different kinds of site conditions, i.e., mountain D. oldhami forest under artificial management （A）, D. oldhami forest on agriculture land under artificial management （B）, riparian D. oldhami forest under artificial management （C）, and unmanaged riparian D. oldhami forest （D）. The results indicated that site conditions have tangible effects on the width of bamboo stump; the effect of site condition on stump quantity is ordered by D〉 A〉 B〉 C, while site condition B is most beneficial to shooting; artificial management measures help the length increase of bamboo stump, thus contributing to the increase of shooting quantity. The study results could provide a basis for the scientific management ofD. oldhami.
