摘　　要：研究了截干萌芽对银杏高生长、单叶干重、单株叶产量和黄酮含量的影响，结果表明：①第一次截干后，银杏高生长量比对照高，第二次截干后，距地３０ ｃｍ 截干的处理高生长也超过对照，约为对照的１２７ ％ ；②截干后，银杏单叶干重显著高于对照；③第一次截干后，银杏单株叶产量显著高于对照，第二次截干后，３０ ｃｍ 截干高度的处理单株叶产量约为对照的１１２ ％ ，且随截干高度的增加，单株叶产量有随着增加的趋势；④截干后，银杏叶中黄酮含量显著高于对照，随截干高度的增加，黄酮含量有下降的趋势。为使银杏叶用园管理方便和获得较高的叶产量和较好的叶质量，建议银杏叶用园应采取截干萌芽这一矮林作业方法。The sprout height,the dry weight of single leaf, the leaf yield of single tree and the flavonoid content in the leaf were evaluated in this paper after cutting with different stump heignt (coppice system)in Ginkgo plantation for leaf harvest.The results indicated that there were higher leaf yield,higher flavonoid content,higher dry weight of single leaf and higher growth after cutting.Socoppice system can not only give the convenience of management in Ginkgo plantations for leaf harvest,but also it can give of Ginkgo plantations for leaf harvest,better leaf quality and higher leaf yield. Hence,the coppice system should be spread in the silvicultural practice of ginkgo plantation for leaf harvest.
