摘要
论述了我国盾叶薯蓣的野生资源现状、人工种植生产现状、资源濒危原因及应采取的保护对策。指出:我国现有盾叶薯蓣野生资源蕴藏量估计在200万kg左右,资源数量已大为下降,然而年需求量却高达2亿kg以上,供需矛盾十分突出。造成资源濒危的主要原因是利用过度、生境及种质资源被破坏、家种者皂素含量低且质量差而不能大批量用于皂素生产。建议在采取有效保护野生资源的同时,尽快建立全国性良种繁育基地,按GAP要求建立我国现代化、规模化、规范化的高产优质药材原料生产基地,从根本上解决当前盾叶薯蓣资源保护与利用的矛盾。
The present discussion focused on the current situation of wild natural resources of Dioscorea zingiberensis in our country,its artificial cultivation,production situation and protection countermeasures that should be taken.It pointed out that at present the wild resource reserves were estimated to be around two million kg and the amount of resource decreased drastically;nevertheless,its annual demand was as high as two hundred million kg.The contradiction between supply and demand was prominent.The main causes leading to its resource extincation were overuse,destruction of habitat and germplasm resources and low content of saponin in domesticated variety,which could not be used in mass production of saponin.It was recommended that propagation base nationwide was established as soon as possible while took effective measures to protect natural resource and that the current contradiction between resource protection and utilization could be resolved once and for all by building modernized,standardized and large-scale production base of high-yield and top-quality medicinal material in keeping with GAP requirements.k
