【摘要】 分析了9年生毛竹实生林不同立地条件对新竹胸径、竹高的影响,结果表明不同立地条件之间新竹胸径、竹高差异显著,立地条件越好,新竹胸径、竹高越大。毛竹实生林胸径、竹高的生长发育进程分析表明前5年增长率较大,5年后呈下降趋势。并估测了毛竹实生林9年生时的经济效益,较为显著。更多还原

【Abstract】 This paper studies the effects of different site conditions of nine years old moso bamboo forest on the breast diameter and height of the new bamboos. The results show that the breast diameter and height of the new bamboos apparently differ under different site conditions. The better the site conditions are, the taller the new bamboos grow and the bigger their breast diameters grow. Besides, an analysis of the growing process of mose bamboo’s breast diameter and height indicates that growth rate tends to be higher in the first 5 years and lower 5 years later. Moreover, the paper also estimates the substantial economic benefits of the nine years old moso bamboo forest.更多还原
