营建油松种子园需用大量嫁接苗木,但一株高大的优树只能提供一,二百个接穗,大量繁殖受到限制。1984年我们用短枝进行嫁接,近年又进一步探索,已找到了一种简单易行,且效果较好的方法,现简介如下:油松的短枝一般称作“针叶束”或“针叶簇”,在顶端优势丧失或受到削弱的情况下.具顶端优势的短枝顶芽有可能恢复分生能力, The construction of Chinese pine seed orchard requires a large number of grafted seedlings, but a tall tree can only provide one or two hundred scion, a large number of breeding is limited. In 1984 we used spur grafting, further exploration in recent years, has found a simple and effective, and the effect is better, are summarized as follows: Pinus tabulaeformis commonly known as “needle bundle” or “needle Leaf clusters ”, in the case of the loss of the top advantage or under the circumstances of the top advantages of spur buds may be able to restore meristematic ability,
