Abstract: To optimize bamboo density for compound management of Polygonatum cyrtonema within a Phyllostachys edulis bamboo forest,population growth conditions,biomass accumulation,and allocation rules of Polygonatum cyrtonema at three different bamboo densities (1 500-2 500,2 500-3 500,and 3 500-4 500 stemshm-2) in extensively managed Phyllostachys edulis stands with similar site conditions were studied. One-way ANOVA showed that for Polygonatum cyrtonema,population density,height,and biomass accumulation of each component as well as total biomass accumulation within bamboo density of 1 500-2 500 stemshm-2 were significantly greater (P<0.05) than them in the other two bamboo densities;whereas no effect on diameter,leaf chlorophyll values,or biomass allocation ratio of each component was realized. Distribution patterns of Polygonatum cyrtonema showed that biomass allocated to underground tubers was significantly greater (P<0.05) than biomass of the sum of roots,leaves,and above stem grounds. Thus,bamboo density was the important factor affecting population growth. And for compound management of Polygonatum cyrtonema in Phyllostachys edulis stands with these site conditions,1 500-2 500 stemshm-2 was best.[Ch,1 fig. 6 tab. 22 ref.]
