贵州续断资源分布状况调查

Investigation on Distribution of Radix dipsaci Asperoidis in Guizhou Province

为摸清贵州省续断资源分布状况,我们历时4年对该省续断资源进行了调查,并对调查结果进行了总结分析。结果表明:全省各地均有续断资源分布,但尤以西部、西南部、北部、东北部海拔1000 m以上的区域最为丰富,约占全省分布区蕴藏量(4500 t)的80%;生长地点主要是山坡、田边、林缘、路旁草灌丛等;生长地土壤多为黄壤。根据资源分布范围和药材质量,贵州西部和西北部、海拔在1000～1700 m的地区为续断最适宜种植区,而海拔在600～1000 m的地方为适宜区,也可适当发展。

Distribution of Radix Dipsaci Asperoidis in Guizhou Province were consecutively investigated forfour years. The results showed that this herb resource distributed over the whole province, but mostly concentrated in the west, southwest, north, northeast area above 1000 m altitude, which accounted for 80% of the provincial reserves （4,500 tons ）. This herbs mainly grown in the hillside, forest edge, roadside grass shrubs. Based on the distribution characters, the western and northwestern areas at 1 000 - 1 700 m altitude were recommended as the most suitable cultivation areas in Guizhou Plateau.
