摘  要：
通过对雷竹引种后新立竹生长进行实地调查 ,结果表明 :母竹引种后新立竹数目、胸径、树高、枝下高及与母竹距离有随着母竹年龄增大而增长的趋势。新立竹数目与新立竹年龄 (相对母竹而言 )之间及新立竹与母竹平均距离之间均存在函数关系。雷竹引种后各年间新立竹数目、胸径、树高、枝下高及新立竹与母竹距离的差异均达到极显著性水平。年龄对雷竹林分平均单株枝重、枝长、叶数 /枝、叶重 /枝、叶面积的影响均没有达到显著性水平。钩梢处理对平均均叶数 /枝、平均叶重 /枝及平均单株枝重的影响达到显著性水平或极显著性水平。雷竹株数按径阶分布服从正态分布。雷竹冠幅、胸径、树高及枝下高等生长因子之间存在相关关系。根据雷竹鞭侧芽分化为岔鞭规律以及新立竹年龄与母竹距离的关系可以确定雷竹初植密度 ,由树冠重叠系数及其平均径阶决定笋用雷竹林经营密度。

摘  要：
The new bamboo culm growth after mother trees planted for bamboo shoots forest of Phyllostachys praecox f. preveynalis have been studied. The results show that the number of new culms, diameter of breast-high, tree height, height of the culm with no branches, and the distance of new culm to mother tree increase with the increase of age of mother tree. There are relationships between new culm numbers and their ages, and between the distances of new culm to mother trees. The differences among the number of new culms, diameter of breast-high, tree height, height of culm with no branches, and the distance of new culm to mother tree among years are obvious. The effect of age on average branch weight, branch length, leaf number per branch, leaf weight per branch, area of 10 leaves, are not obvious. The effect of top bud cutting on average branch weight, leaf weight per branch, leaf number per branch are obvious. The number distribution of diameter grade obeys normal distribution. There are regressive relationships among diameter of breast-high, tree height, height of culm with no branches and crown diameter. According to the characteristics of rhizome development and the distance of new culm to mother trees, the density of mother tree can be determined, and the management density of bamboo shoots forest of F.preveynalis by means of diameter grade can also be determined.
