摘要
通过对黔北山区31个样地的调查,分析了不同立地因子对撑绿竹3号平均冠幅、平均篼幅等营养空间因子的影响;同时分析了冠幅与造林密度的关系。
Bambusa pervariabilis ×Dendrocalamopsis daii is a hybrid of Bambusa pervariabilis McClure as female with Dendrocalamopsis daii Keng as male parent. Some clones like Barnbusa pervariabilis×Dendrocalamopsis daii No. 3,No. 6,No. 8 and No. 30 were selected. The clone Barnbusa pervariabilis × Dendrocalamopsis daii No. 3 was introduced to north Guizhou for pulp. Through a survey of 31 plots,the effects of site factors such as altitudes, slope position, slope direction, slopeness, soil type and soil thickness on the vegetation spaces about crown dimension and stump dimension of Barnbusa pervariabilis ×Dendrocalamopsis daii No. 3 were studied. Meanwhile, the relation between crown dimension and the planting densities was analyzed.
