摘要
楠木是我国珍贵优良的材用树种资源,经济价值高。为了明确立地环境对楠木生长的影响、给楠木这一珍贵树种的造林提供技术和方法,比较了不同林分、坡向、坡位以及林分郁闭度下楠木幼树的造林成活率、生长量以及叶片光合色素含量、光合速率。结果显示郁闭度为0.55~0.75的杉木林北坡的下坡位楠木生长状况最佳。试验可为楠木人工造林筛选出适宜的立地条件,为皖南山区造林提供技术指导。
Phoebe zhennan is a high-quality timber tree species in China with high economic value.In order to clarify the influence of site environment on the growth of P.zhennan,and provide techniques and methods for the afforestation of P.zhennan,a precious tree species,in this study,the survival rate,growth,photosynthetic pigment content and photosynthetic rate of P.zhennan young trees were compared under different stands,slope directions,slope positions and canopy density.The results showed that the growth of P.zhennan was the best on the lower slope of the north slope of Chinese fir forest with canopy density of 0.55-0.75,and suitable afforestation site conditions were screened out,which provided technical guidance for afforestation of mountains in the south of Anhui.
