银杏是我国珍稀树种。幼苗嫁接是快速建立早产、丰产、稳产银杏园的基础。经过多年实践,我们总结出了秋季枝接的方法,不但简便,而且嫁接时间长,成活率高,成活后生长势强,树冠形成快,结果早。 1.枝条采集 (1)接穗的选择。应选当地已开始结果的优良银杏树种作采种母树,如京山14号、大佛手等。在新梢停止生长、枝条已木质化时采集,剪取的接穗应是当年发 Ginkgo is a rare species in our country. Seedling grafting is the basis for the rapid establishment of preterm, high yield and stable yield of ginkgo garden. After many years of practice, we concluded that the method of autumn grafting is not only simple, but also long grafting, high survival rate, strong growth after survival, crown formation faster, the result is early. 1. Branch collection (1) the choice of scion. Should choose the local ginkgo trees have begun to produce good results for the mother trees, such as Jingshan on the 14th, Big Buddha hand.
