银杏当年生苗嫁接技术试验

Grafting Test on One-year Seedlings of Ginkgo biloba

以银杏当年生半木质化小苗作砧木,用贴芽接和绿枝接进行嫁接对比试验。结果表明:贴芽接和绿枝接的平均成活率分别为77％和85％。嫁接时间以8月中旬气温回落、干旱缓解时为最好。

Using one-year seedlings of Ginkgo biloba with semilignification as tree stock, the comparative results of the two grafting methods showed that the average survival percentage of veneer-bud grafting and green grafting were 77 and 85 percent, respectively. The middle of August was a good period for grafting, in which there was a drop in the air temperature and a relaxation in the drought.
