摘　　要： 对不同年龄组成的绿竹丛产笋量对比、丛立竹数和该丛当年笋产量的回归关系、以及绿竹丛立竹数 ( N)与丛冠幅 ( CW)的回归分析 ,结果表明 ,不同年龄组成的绿竹丛平均单株产笋量差异显著 ,由 1、 2年生竹组成的绿竹丛平均单株产笋分别比由 1～ 3年生竹组成的绿竹丛和 1～ 4年生竹组成的绿竹丛多 0 .1 638kg和 0 .1 979kg.丛立竹数为 4～ 7(株 /丛 )的绿竹林 ,在相应最大密度下可获得最大笋产量 (笋产量大于 4650 kg/hm2 ) .研究结果提出了绿竹林丰产结构指标 。 The yield of new bamboo of Dendrocalamopsis oldhami per clump under different age structure are compared The regression relationship between the individual numbers per clump and the yield of new bamboo of the clump in the same year, width of clump crown are analyzed The results show that the average yield of new bamboo per individual differs significantly under different age structure for clump The average yield of new bamboo of individual from clump with one and two years old is by 0 163 8kg and 0 197 9kg heavier than that with one, two, three years old and with one, two, three and four years old When D oldhami forest have four to seven individuals per clump, it has the highest yield in new bamboo(more than 4 650kg/hm 2 ) under accordingly maximize density The research will give serve for the high yield structure ofD oldhami forest and can provide direction for the culture of high yield forest of D oldhami
