穿龙薯芋(穿山龙)Dioscorea nipponica Makino.为合成各种类型的避孕药和甾体激素类药物的重要原料。近年由于国内甾体激素类药物迅速发展,依靠野生资源将远不能满足需要,因此,变野生为家栽,制定合理的培措施,对提高产量和薯芋皂甙元含量有重要意义。为此,我们在北京地区引种并观察和研究该植物生长与发育过程,今将所获得的资料总结如下:
Dioscorea nipponica Makino. is an important raw material for the synthesis of various types of contraceptives and steroid hormones. In recent years, due to the rapid development of domestic steroid hormone drugs, relying on wild resources will not be able to meet the needs. Therefore, changing the wild into a home plant and formulating reasonable cultivation measures are of great significance for increasing yield and content of diosgenin. To this end, we introduced and observed and studied the growth and development of the plant in the Beijing area. The information obtained here is summarized as follows:
