一、引言杜仲(Eucommia ulmoides Oliv.)原为我国特产树种,早在千年前已为民间栽培作药用:根据本草纲目记载:“杜仲润肝补肾,强筋骨,治腰膝酸痛”。近年来又用作治疗高血压症,亦颇有成效。而它另一重要的特性是含有硬性橡胶。在1906年引种到苏联的杜仲,已开始大量提胶。其他如德、英、法各国也有一些杜仲研究工作。我国目前正处于社会主义大建设时期,为满足日益需要的硬橡胶原料和国内外所需的药用杜仲,政府先后设置几处专业杜仲林场,并发动群众造林。某些科学研究机构和高等学校也进行了杜仲种子、种苗及含胶量的分析工作,并得到初步结果。为进一步了解 I. Introduction Eucommia ulmoides Oliv. Was originally endemic to China, as early as thousands of years ago for civil cultivation for medicinal purposes: According to Compendium of Materia Medica records: “Du Zhong Run liver and kidney, strong bones, treatment of waist and knee pain.” In recent years, it is also used for the treatment of hypertension and is also quite effective.

In order to meet the increasingly needed hard rubber raw materials and medicinal Eucommia needed both at home and abroad, the government has set up several professional Eutrophic forest farms and mobilized mass afforestation. Some scientific research institutions and colleges and universities also conducted the Eucommia seed, seedling and gel content analysis, and obtained preliminary results. To learn more
