我们于1990年至1991年在地处海拔110米的万源县曾家乡一村二社王天中的承包地上进行了用杜仲根培育幼苗栽培试验,取得了显著效果,且方法简单,深受群众欢迎。一、用根繁殖幼苗的好处(一)可有效地解决种源不足问题由于近年杜仲价高,商品树龄大大缩短,大龄结籽树少,种源不足,且种子育苗发芽出苗率低,仅采用种子繁殖已不能满足目前发展的需要。用根繁殖,取材广泛,只要
In 1990-1991, we conducted the seedling cultivation experiment with Eucommia root nurture on the contracted land of Wang Tianzhong, the second sub-village of Zengjia village, Zengjia village, Wanyuan county, Wanyuan County, 110 meters above sea level, and achieved remarkable results. The method was simple and welcomed by the masses . First, the advantages of root breeding seedlings (A) can effectively solve the problem of insufficient seed Due to the high price of Eucommia in recent years, greatly shortened commodity age, older seedling less, lack of provenance, seed germination and seedling emergence rate is low, only the use of Seed breeding has been unable to meet the needs of the current development. Breeding with roots, widely drawn, as long as
