毛竹为单轴型散生竹，属典型的无性系植物，原产我国亚热带地区。由于其个体高大、生长迅速、产量高、材质好、分布广，长期以来，一直是我国最为重要的经济竹种。本文应用无性系生长生理整合的理论，从种群统计学的角度，探讨了毛竹林立竹密度与叶龄结构对其无性系生长潜力的影响。结果表明：由于毛竹叶的生活期为两年，１龄新叶的光合能力比２龄老叶高，每样地的出笋数、活笋数与带１龄新叶的立竹数呈正相关，而与带２龄老叶的立竹数相关性不显著。另外，竹笋的死亡率是非密度制约的。本研究结果合理地解释了常见的毛竹林产量大小年交替变化的现象。 Bamboo is a uniaxial type of loose bamboo, is a typical clonal plant, native to China’s subtropical regions. Because of its individual tall, rapid growth, high yield, good material, widely distributed, for a long time, has been China’s most important economic bamboo species. In this paper, the theory of physiological and physiological integration of clonal growth was used to investigate the effects of bamboo density and leaf age structure on the growth potential of clones in Moso bamboo forest from the perspective of population statistics. The results showed that since the life span of Phyllostachys pubescens leaves was two years, the photosynthetic capacity of the first-instar new leaves was higher than that of the second-year old leaves. The number of bamboo shoots per shoot and the number of live bamboo shoots were positively correlated with the number of bamboo stands , But there was no significant correlation with the number of standing bamboo with 2-year old leaves. In addition, the mortality of bamboo shoots is non-density-restricted. The results of this study can reasonably explain the common alternations of annual and annual yields of Phyllostachys pubescens forest.
