一种用于树木剥皮后长皮、保树的生长剂—“植物增皮素”最近在湖南问世,解决了杜仲生产砍树剥皮的难题,并获得国家专利。杜仲树皮是中医常用的珍贵中药材,过去取皮都是采用砍树剥皮的方法,结果致使杜仲资源逐年减少。为了解决这一难题,全国各地曾在剥皮再生技术上开展攻关,1989年曾研究出一种“环剥法”技术,可在立木上环剥皮层,但由于树干环剥后伤口不易愈合,所剥树株成活率低(尤其在大龄树上表现更为突出),因而难于推广。近年来,湖南省林科院科技人员在“环剥法”的基础上。进行了多学科的交叉研究,
A kind of growth agent for the long-skinned and preserved tree after the tree is peeled off - “Plant Epidermins” recently came out in Hunan, which solved the problem of de-barking the eucommia barks and obtained the national patent. Eucommia bark is commonly used in traditional Chinese medicine precious traditional Chinese medicine, the past is the use of dehulling tree felling method, resulting in eucommia resources decreased year by year. In order to solve this problem, all over the country have carried out research in the skinning regeneration technology, in 1989 had developed a “girdling ” technology, can ring peeling in the standing layer of wood, but because the trunk after girdling the wound is not easy to heal , The survival rate of peeled trees is low (especially in the older trees are more prominent), which is difficult to promote. In recent years, Hunan Academy of Forestry Science and Technology personnel on the basis of “” “stripping law.” Conducted a multidisciplinary cross-study,
