银杏实生苗双向无性繁殖配套技术的研究

Studies on the serial technology of vegetative propagation in double courses of Ginkgo biloba L.seedling

用银杏良种培育 1年生实生苗 ,然后将苗木截干培大苗或截干嫁接 ,同时 ,利用截干下来的主干扦插 ,形成双向无性繁殖配套技术 ,不仅大大提高苗木的繁殖系数 ,提高土地利用率 ,大幅度提高经济效益 ,而且方法简单易行 。

The serial technology of vegetative propagation in double courses of Ginkgo biloba L.seedling is that the plants were cultivated from yearlings that cultivated using fine breeds and strains on the yearlings were cut for grafting,and then the truncated plants were cut.The propagation coefficient increased very much by using it.
