银杏硬枝嫁接通常在春季进行，嫁接时间较短，不能满足生产的需要。为了延长银杏的嫁接时间，我们从1988年以来在江苏省如桌市进行了银杏夏秋硬枝嫁接技术试验，共嫁接万株以上银杏，成活率95％以上。现将技术要点简介如下。（1）嫁接方法在江苏省如桌市从7月下旬至9月中旬均可 Ginkgo hardwood grafting is usually carried out in the spring, grafting time is short, can not meet the production needs. In order to extend the grafting time of Ginkgo biloba, we conducted a summer and autumn hardwood grafting experiment in Jiangsu Province such as the Table City since 1988, grafting more than 10,000 ginkgo trees with a survival rate of over 95%. Now the technical briefings are as follows. (1) The grafting method in Jiangsu Province such as table and table from late July to mid-September can be
