摘　　要：对茶杆竹出笋成竹规律及其合理立竹密度进行研究，表明茶杆竹出笋量随时间的变化进程为“少-多-少”。茶杆竹笋期呈“S”型曲线。不同笋期的茶杆竹高生长方程相关系数为0．9371-0．9418．经检验，达到显著水平，表明用Logistic方程回归效果较好。茶杆竹立竹密度试验表明茶杆竹林分密度应以11250株／hm^2为适宜。We have studied on Psudosasa amabilis growth regularity and its probably suitable density. The results showed the shoots growth of Psudosasa amabilis are firstly slower and then become faster, at last get slower again. Its growth eharecter twing shooting period is ＂S＂ curve. The different shooting period of Psudosasa amabilis growgh equation relevance coefficient were 0. 9371-0. 9418. They have been reached significant level after inspection and result of Logistic Regression equation is relatively good. The experiment of psudosasa amabilis desity showed that its suitable density was 11250 plant ha^-1
