一、陕南杜仲资源概况陕南杜仲有粗皮和光皮两种类型,但大多为粗皮类型。近年来,略阳县药材公司还发现了红皮类型和白皮类型,而且认为白皮类型较好。这次调查时,我们也偶见有些杜仲的内皮呈粉红色,但大多数呈白色。所以,这种现象的出现是由别的什么原因引起的,还确是两种不同的类型?尚待进一步研究。陕西省现存杜仲林(1985年统计资料)35万亩,6100万株,秦岭以南地区约占97.7%
First, the southern Shaanxi Eucommia Eucommia Eucommia have two types of bark and light skin, but most of the bark type. In recent years, Lueyang County herbs company also found red skin type and white skin type, and that the white skin type is better. At the time of this survey, we also occasionally found some of the endothelial cells of Eucommia ulmoides pink, but mostly white. Therefore, the emergence of this phenomenon is caused by other reasons, is indeed two different types? For further study. In Shaanxi Province, there are 35 million mu of Duzhonglin (1985 statistics), 61 million, accounting for 97.7% of the area south of the Qinling Mountains.
