为了保护珍稀濒危药用植物资源——管萼山豆根,对其形态特征、种植条件、物候期、生长发育特性及仿野生栽培进行了研究。结果表明:管萼山豆根为常绿灌木,生长在海拔700～1 000 m的山沟两边的阴湿陡壁上,有明显的生长规律;因其种子繁殖困难,扦插繁殖和组织培养的管萼山豆根生长相当缓慢,完全人工种植成本较高,故仿野生栽培是一种较为理想的繁殖方式。 In order to protect the rare and endangered medicinal plant resources - the tube Eupatorium soongorum, its morphological characteristics, planting conditions, phenology, growth and development characteristics and imitation of wild cultivation were studied. The results showed that the root of C. calyx was rooted in evergreen shrubs and grew on the wet and darkest sides of the ravine with an elevation of 700-1000 m with obvious growth pattern. Due to the difficulty of seed propagation, the calyx of cuttage propagation and tissue culture Hill bean root growth is quite slow, completely artificial higher cost of planting, so Imitation wild cultivation is a more ideal way of reproduction.
