| 摘 要： | 为了探索龙芽楤木食药兼用林的人工栽培模式,对不同培育年龄和林地位置的龙芽楤木的根产量和根皮产量进行了调查.结果表明:龙芽楤木的根皮率随着根龄的增加而下降,培育年限越短,单位面积根皮的年产量就越高;龙芽楤木栽培的边缘优势非常明显,林地边缘植株的根产量、根皮产量及根皮率均高于林地中间植株.

| Abstract: | In order to explore artificial cultivation pattern,root and root bark yield of Aralia elata at different nurturing ages distributed on different field locations were investigated. The results showed that the root bark ratio decreased along with the increase of root age,root bark output was higher in stand with short nurturing age; edge effect was evident on root growth of Aralia elata,the yield of root and root bark as well as root bark ratio were higher at stand edge than that inside stand. |
