本文通过对银杏插穗的生理、生态研究，运用物理学方法进行生态控光调节，促使插穗先长粮后抽梢发叶，改变了常规扦插先前叶后长根的局面，有利于扦插苗的成活和生长。使供试插穗发根率达100％，扦插成活率达100％，当年合格苗出圃率达90％。
In this paper, the physiological and ecological research of Ginkgo biloba cuttings, the use of physical methods of ecological control of light, prompting the first spike long after cutting leaves, changing the conventional cuttings after the previous root after the long leaves of the situation is conducive to the survival of cuttings And grow. The test cuttings hair root rate of 100%, cuttings survival rate of 100%, then qualified seedlings out of garden rate of 90%.
