摘　　要：[目的]研究滇中地区华山松-旱冬瓜天然混交林不同郁闭度对6种中草药地下药用部分生长量及产量的影响。[方法]在华山松-旱冬瓜天然混交林下,0.2、0.4、0.7郁闭度下种植云木香、桔梗、党参、附子、秦艽、珠子参,研究不同郁闭度对中草药地下药用部分生长量及产量的影响,选择出不同郁闭度下最适宜种植的中草药品种。[结果]滇中地区旱冬瓜-华山松天然混交林在郁闭度为0.2的林分下,可套种云木香、桔梗、秦艽、附子;郁闭度为0.4的林分下,可套种党参;郁闭度为0.7的林分下,可套种珠子参。[结论]该研究为滇中地区林下不同郁闭度套种中草药的品种选择提供参考。[ Objective] The research aimed to study the effects of different canopy density on the growth and yield of underground medicinal part of six Chinese herbal medicine in the natural mixed forest of Pinus armandi and Alnus nepalensis in central Yunnan Province. [ Method] Under the natural mixed forest of Pinus armandii and Alnus nepalensis, 0.2, 0.4 and 0.7 canopy density were used to plant Sauussurea costus ,Platycodon grandiflorus, Codonopsis pilosula ,Aconitum carmichaeli, Gentiana macrophylla and Rhizoma panaois Majoris, the effects of different canopy densi-ty on the growth and yield of underground medicinal part of Chinese herbal medicine were studied,the varieties of Chinese herbal medicine suit-able for different canopy were selected. [ Result]The natural mixed forest of Pinus armandi and Alnus nepalensis in central Yunnan Province could be intercropped with Sauussurea costus ,Platycodon grandiflorus, Gentiana macrophylla and Aconitum carmichaeli under the 0.2 canopy density. In the 0.4 canopy density,could be intercropped with Codonopsis pilosula;in the 0. 7 canopy density, could be intercropped with Rhizoma panaois Majoris. [ Conclusion] This study provides a reference for the varieties selection of Chinese herbal medicine under-forest intercropping in different canopy density.
