营建油松种子园需要大量嫁接苗木,但一株高大的村只能提供100～200个接穗,大量繁殖受到限制。1998年我们用短枝进行嫁接,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,萌动并发育成正常枝条。因此,采用短枝嫁接是可行的。 1 嫁接方法 用3年生健壮的油松做砧木,嫁接部
The construction of Chinese pine seed orchard requires a large number of grafted seedlings, but a tall village can only provide 100-200 scions, large-scale reproduction is limited. In 1998, we used short branches for grafting and found a simple and effective method. The brief introduction is as follows: The short branches of Pinus tabulaeformis are generally called “needle bundle” or “needle cluster” In the event of the loss of or diminution of the superiority of the apical meristem, it is possible for the apical bud with the superiority to regrow viability, germinate and develop into normal shoots. Therefore, the use of short grafting is feasible. A grafting method with 3-year-old robust pine as rootstock, grafting
