一、前言杜仲皮是我国传统名贵中药材,近代医学又用于治疗高血压,国内中药配方及援外出口需要量大,而杜仲生长周期长,资源日竭,供需矛盾突出,据有关资料,1977年全国收购量仅能满足国内配方需要的20%,还有逐渐下降的趋势。因此保护现有资源,合理利用、提高产量、增加收益成为当前的重要课题。七十年代中,开展了杜仲“环剥”再生;以叶代皮等综合利用的研究,取得一定成效。但由于实施过程中,对内、外在条件有严格的选择性或局限性,对某个技术环节尚待进一步探讨,有碍全面推广应用,故大部份产区仍沿用“杀鸡取卵”的剥皮方法。故杜仲皮供需矛盾,未见缓和。
I. Introduction Eucommia bark is a precious traditional Chinese herbal medicine in our country. Modern medicine is also used to treat high blood pressure. The demand of domestic traditional Chinese medicine formulation and foreign aid export is large. However, the growth cycle of Eucommia ulmoides is long and resources are exhausted. The contradiction between supply and demand is prominent. According to relevant information, The national takeover volume can only meet 20% of the domestic formula needs, and there is a gradual downward trend. Therefore, it is now an important issue to protect the existing resources, make rational use of them, increase production and increase profits. In the seventies, Eucommia “girdling” regeneration was carried out; and the research on the comprehensive utilization of leaves and skins achieved some success. However, since the implementation process, the internal and external conditions have strict selectivity or limitations, a technical aspects yet to be further explored, hinder the full promotion and application, so most of the producing areas are still using “to kill the egg” skinning method. Therefore, the conflict between supply and demand Eucommia, no ease.
