陕西特有珍稀濒危植物灰毛岩风的迁地保育技术

Ex Situ Conservation of Libanotis spodotrichoma in Shaanxi

灰毛岩风(Libanotis spodotrichoma)为伞形科(Umbelliferae)岩风属(Libanotis)多年生亚灌木状草本,为秦岭地区“太白七药”之一,俗称“长春七”。该物种为陕西特有植物,产户县、周至、眉县、佛坪、宁陕、旬阳、山阳,生于海拔1100~1800 m的山地岩石上。目前关于灰毛岩风的研究仍处于空白的状态。本研究在广泛研究和试验的基础上,探讨了灰毛岩风的习性和迁地保育技术,为下一步资源的研究和利用打下了基础,也为其它珍稀濒危岩风属植物的保育研究提供实践参考。

Libanotis spodotrichoma is a perennial subshrub herb of the genus Elliferae of the Umbelliferae family.It is one of the“Taibai Seven Medicines”in the Qinling region,commonly known as“Changchun Seven”.The species is endemic to Shaanxi,distributing in counties like Zhouzhi,Meixian,Foping,Ningshan,Xunyang,and Shanyang,etc.It grows on mountain rocks from 1100 to 1800 m above sea level.At present,the study of Libanotis spodotrichoma is still in a blank state.On the basis of extensive research and experiments,this paper discusses the habits and techniques of ex situ conservation of Libanotis spodotrichoma,a practical reference for conservation research of other rare and endangered Libanotis Hill plants.
