毛竹林分密度效应的初步研究

Preliminary Study on Density Effect of Mao Bamboo Plantation

本文研究了福建毛竹最适宜区,一般经营不钩梢的竹林立竹密度对毛竹林平均胸径、竹高、枝下高、单株杆重,重量蓄积以及新竹产量等所产生的作用规律。结果表明,立竹密度与上述竹林结构因子存在非线性函数关系。在一般经营管理条件下,立竹密度2700～3000株/hm^2为宜。

This paper deals with the effect of density of the standing bamboo upon mean diameter, mean heitht, height under crown, stem weight , stock of weight and yield of fresn bamboo under ordinary mangement in regions of climatic optimum for Mao bamboo. The result showed that there was non-linear function felatibnship between the density and the above-mentioned factors. It was suggested that the optimum density of the standing bamboo would be in the range of from 2700 to 3000 stem per ha. under ordinary man-agement.
