摘要
以香樟幼龄林为研究对象,研究修枝强度对香樟幼龄林胸径、树高和材积生长的影响。结果表明:修枝强度对香樟幼龄林的胸径、树高和材积生长均有极显著影响,当修枝高为树高1/4时,促进香樟的生长;当修枝高大于树高1/3时,抑制香樟的生长。
Taking the young forest of Cinnamomum camphora as the research object,the effect of different pruning strengths on the DBH,tree height and volume growth was studied.The results show that pruning has a significant effect on the DBH,tree height and volume growth of young forest of C.camphora.When the pruning height is 1/4 of the tree height,it promotes the growth;while the pruning height is more than 1/3 of the tree height,it,inhibit the growth of camphor.
