黄柏树皮是一种重要的中药。长期以来,黄柏树皮都是采用伐木取皮的方法剥取的,严重地影响了这种资源的长期利用。从1975年以来,我们在辽宁的一些地区进行了大面积的环剥试验,发现在2—3年内都能长成完整的新皮。这种新皮再环剥仍能重新形成新的再生皮。近年来,在黄柏、杜仲、厚朴、白腊树等树干上都环剥成功。为了进一步阐明环剥成活的机理,我们对黄柏剥皮再生的组织分化,进行了解剖学观察。 Cork bark is an important traditional Chinese medicine. For a long time, the cork barks are stripped by the method of cutting the timber and severely affecting the long-term utilization of such resources. Since 1975, we conducted extensive girdle tests in some parts of Liaoning and found that we could grow a complete new skin in 2-3 years. This new skin re-girdling can still re-form a new regeneration skin. In recent years, cork, Eucommia, Magnolia, white wax tree trunk are all girdling success. In order to further elucidate the mechanism of girdling survival, we conducted an anatomical observation on the tissue differentiation of cork skin regeneration.
