垂柳是深受群众欢迎的优良绿化树种。但由于出现“六月雪”而使人烦恼。近几年城市绿化多半采用雄株,垂柳在不飞絮的时候,从根株外形是很难分辩的,做上标记还得等待一年。因此,我们于1986—1987年开始搞嫩枝扦插繁殖试验,收到了较好的效果。 Weeping willows are popular green tree species. However, it was annoying due to the June snow. In recent years, urban greening mostly adopts male plants, weeping willow in the non-Fei Xu, the root shape from the root is difficult to distinguish, marking have to wait a year. Therefore, we started the tender shoot propagation experiment from 1986 to 1987, and received good results.
