银杏是深受群众喜爱的经济和用材树种。但是,银杏用实生苗栽培要20年左右才能开花结果,有人用8～10年生、胸径10厘米的实生或分株幼树作砧木,进行嫁接,比实生树提早3～5年结果。为使银杏提早结果、改进品质,提高产量,我们在1984年进行了银杏幼苗嫁接试验,嫁接成活率达到87.5％以上,现将试验结果作一报道。
Ginkgo is popular with the masses of economic and timber species. However, Ginkgo biloba seedlings are planted with seedlings about 20 years before they are able to bloom. Some people use 8 to 10 year-old and 10 cm diameter breasts as rootstocks or grafted saplings for grafting, 3 to 5 years earlier than the real trees. In order to make early results of ginkgo, improve quality and increase yield, we carried out the grafting test of ginkgo seedlings in 1984, the grafting survival rate reached more than 87.5%, now the test results for a report.
