圆柏(Sabina chinensis)是深受人们喜爱的观赏树种。由于种源较少,播种和扦插繁殖均困难,苗木远远不能满足绿化建设的需要。我们从1981年开始采用嫁接方法,在河北省东陵林场繁殖圆柏苗木取得较好效果。一、嫁接时间在东陵地区以7—9月上旬为宜。此时,圆柏新梢接近停止或已停止高生长,而径生长仍处于旺盛阶段,形成层活动能力强,嫁接后愈合组织形成快,成活率高。同时,因新梢尚未完企木质化,接穗硬度小,有利于削面切削,
Sabina chinensis is a popular ornamental tree species. Due to less provenance, sowing and cutting propagation are difficult, seedling far can not meet the needs of greening. We began to adopt the grafting method in 1981, and obtained good results in breeding birch seedlings in Dongling Forest Farm in Hebei Province. First, grafting time in the Dongling region in early July-September is appropriate. At this moment, the young shoots of Sabina przewalskii came to a halt or stopped growing at a high level, while the diameter growth was still in a vigorous stage, the ability to form a layer was strong, the healing tissues formed rapidly and the survival rate was high after grafting. At the same time, because the tip has not yet finished the lignification, scion hardness, is conducive to noodles cutting,
