加速银杏繁殖,培育优质苗木对发展银杏生产具有极其重要的意义。银杏嫁接方法多以春季皮下嫁接,也有采用切接、嵌接的。吴县东山以往多用大砧切接,不适合商品苗生产,改用小苗嫁接以来,多在春季用成熟枝作接穗进行切接。嫁接适期短,大量育苗时,受到限制。1989～1990年我们试用绿枝嫁接,取得了较好效果。现将试验结果报告于后。 Accelerate ginkgo breeding, nurturing high quality seedlings for the development of ginkgo production is extremely important. Ginkgo grafting methods are mostly subcutaneously grafted in spring, but also the use of cut, embedded. Wuxian Dongshan in the past with more anvil cut, not suitable for commodity seedling production, use the seedlings grafting, and more in the spring with mature branches for the scion cut. Short duration of grafting, a large number of nursery, is limited. From 1989 to 1990, we tried green grafting and achieved good results. The test results are reported later.
