毛竹是我国的主要栽培竹种之一,面积占竹林总面积的70％左右。它的竹杆高大,管理得好的竹材产量也很高。多年的毛竹生产实践证明:毛竹林合理的群体结构,对毛竹的生长及其产量有着极为重要的作用。不同的坡度、坡向,不同立地条件和不同的管理水平情况下,毛竹的最适密度是有所差别的。要确定某一特定的条件下毛竹最适的立竹密度牵涉到众多的因子,需作大量的调查测定与计算,目前还不能对它作出结论。本文仅就毛竹冠层各层次的叶面积分布,光的透射及各层的光合速率进行研讨。
Bamboo is one of the main cultivated bamboo species in China, accounting for about 70% of the total bamboo forest area. Its tall bamboo, well-managed bamboo production is also high. Years of bamboo production practices have proved that: Moso bamboo forest reasonable population structure, growth and yield of bamboo has a very important role. Different slope, aspect, different site conditions and different management levels, the optimum density of bamboo is different. To determine the bamboo under a particular conditions the most appropriate bamboo density involves a number of factors involved in the need for a large number of survey determination and calculation, it can not yet conclude it. In this paper, the leaf area distribution, light transmission and photosynthetic rate of all layers of bamboo canopy were discussed.
