不同海拔毛竹林生长与均匀度整齐度的研究

对不同海拔高的毛竹林生长，立竹的均匀度及整齐度调查分析，结果表明：海拔高度对竹林生长，均匀度及整齐度具有一定影响，在一定范围内，立竹的均匀度，整齐度随海拔的升高而逐渐减少，科学经营竹林度及整齐度具有一定影响，在一定范围内，立竹的均匀度，整齐度随海拔的升颃是逐渐减小，科学经营竹林采取劈草，松土，深翻等留笋养竹和合理采伐措施，特别是施肥，能有效改善竹林地下部分生长，从而有利于立竹合理利用光能和营养空间，不仅提高了竹林立竹的均匀度和整齐度，而且促进了竹林出笋量和产量的增长。

Studies on the Growth, Even Degree and Uniform Degree of Phyllostachys pubescens Forests in Different Altitudes

The investigation results indicated that the growth, even degree and uniform degree of Phyllostachys pubescens forests were certainly affected by altitudes. Within a certain range, the even degree and uniform degree of bamboos gradually reduced with the increase of the altitude. The underground growth was effectively improved and the utilization of solar energy and nutritious space was improved by scientific management measures, such as chopping grass, loosening the soil, deep tillaging, remaining bamboo shoot and cutting rationary, particularly by fertilizing. Meanwhile the shooting quantity and yield were promoted.
