凌云白毫古茶树资源现状及保护对策

A Field Survey on the Resource of Lingyun Baihao ancient tea plants

凌云白毫古茶树作为广西本土古茶树资源,生长历史悠久,但其野生古茶树和古茶园的地理位置和数量并未得到有效记载。本项目经实地调查研究后发现,凌云白毫野生古茶树零散分布于具有数百年历史的风香坪、先锋岭等地区,但数目所剩无几。野生凌云白毫具有不同程度的病虫害,甚至濒于死亡;在先锋岭地区发现了典型的现阶段存活的、最古老的凌云白毫古茶树,且从地理分布和茶树生长状况上看,这些野生凌云白毫古茶树就是近、现代用于人工栽培茶园的种子源头。本研究可为凌云白毫古茶树的溯源、原生境种质资源保护及其开发与利用等提供一定的理论依据。

Lingyun Baihao ancient tea plants,as a native ancient tea plant resource in Lingyun mountain of Guangxi,have a long history.However,they have become rare and endangered species,due to the loss of suitable habitats and?the geographical location and the number of wild ancient tea plants in Lingyun mountain have not been effectively recorded.The field survey result in the present work showed that Lingyun Baihao were distributed in Fengxiangping,Xianfeng Ridge and other places with hundreds years history,but the number of them was few.The wild Lingyun Baihao have been attracted by pests and diseases in some degree so that they are on the verge of death.The typical Lingyun Baihao ancient tea plants were found in Xianfeng Ridge,and we could infer that these wild ancient Lingyun Baihao tea plants should be the seed source of modern times and modern cultivated Lingyun Baihao tea plants according to their geographical distribution and growth status.This study would provide a certain theoretical basis for the traceability,conservation and utilization of Lingyun Baihao ancient teaplants.
