以龙芽楤木2年实生根为材料,营造药用人工林,采用秋季平茬春季培育萌条的方式进行生产管理。连续5a对造林地的龙芽楤木植株根系及根皮产量进行调查分析,其结果表明:龙芽楤木根系在根龄3～6a生长旺盛,根龄7a时其延长生长停止,加粗生长迅速,根皮老化明显。根龄为3～5a时可剥取的根皮部分比例较高,随后下降。根龄4a时可取皮根段的出皮率及单株出皮率最高,随后下降。其单株根皮总产量和年平均产量在根龄6a时达到最大值,之后开始下降。在不考虑药用品质的前提下,龙芽楤木药用林以根龄6a为生产周期较为适宜。
With 2-year-old root of Radix Alnus cremastogyne as the material, the medicinal plantation was created, and the production management was carried out by cultivating the sprouts in autumn stubble spring. The results showed that the roots of Radix Alnus somaca grew vigorously from 3 to 6a root growth at root age 7a, the growth was stopped at the root age of 7a, Rapid, root bark aging significantly. Root root age of 3 ~ 5a peelable root bark part of a higher proportion, then decreased. The root exudation rate of dermatophyte 4a and descendability rate of per plant were the highest when root age was 4a, then decreased. The total root bark yield and annual average yield reached the maximum at root age 6a, then decreased. Regardless of the premise of the medicinal quality, Longya alder medicinal forest roots 6a for the more appropriate production cycle.
