杜仲树皮是一种重要的医药和工业原料,亟待大力地生产和发展。当前杜仲生产上需要解决的有两个问题:一是要提高杜仲皮的质量;二是要加快杜仲皮再生产的步伐。针对上述问题,我省林业部门的科技人员进行了有益的探索,对杜仲树剥皮再生技术作了一些改进,使杜仲树第1次剥皮后2～3年内可再次剥皮,且新皮质量和厚度与第1次剥皮无明显差异,为杜仲树皮的再生产找到了一条良好的途径。其技术要点于下:1.树龄选择。为保证杜仲树再生皮的厚度、宽度、杜仲胶含量和新皮的形成,长势好的杜仲树年龄须满5年时进行第
Eucommia bark is an important pharmaceutical and industrial raw materials, urgent need to vigorously produce and develop. The current production of Eucommia need to be resolved on two issues: First, to improve the quality of Eucommia bark; second is to speed up the pace of reproduction of Eucommia bark. In response to the above problems, our province’s forestry departments of scientific and technical personnel conducted a useful exploration of Eucommia strioe regeneration technology to make some improvements, so that Eucommia tree peeled 2 to 3 years after the first stripping, and the new skin quality and thickness No significant difference with the first peeling, bark for Eucommia bark reproduction found a good way. The technical points in the following: 1. Tree age choice. In order to ensure the thickness, width, the content of Eucommia ulmoides and the formation of new skin of Eucommia rencesta, the growing Eucommia tree should be completed in 5 years
