雪松主要用种子育苗,需要30年左右才能结实,同时雪松的雄株多、雌株少,为了培育更多的采种母树,1982年春,我们试验用多枝高接方法,接后4年就开始结实,比雪松自然结实期提早20余年。嫁接砧木使用生长健壮、层性好、层间距大,通风透光好的10年生以上的雪松。嫁接选择3—5年生永久枝的理想部位。3 Cedar seed mainly with seedlings, it takes 30 years or so to be strong, at the same time the cedar male plant more, less female plants, in order to cultivate more seed trees, in the spring of 1982, we test the method with a number of branches, followed by 4 years Strong, more than 20 years earlier than natural cedar seed. Grafted rootstocks are grown with strong growth, good layering, large layer spacing and good ventilation and light. Grafting choose the ideal part of 3-5 years permanent branch. 3
