摘要 银杏为北京地区常用的园林绿化树种,其叶型优美、秋季满树金黄,观赏价值较高。但在园林绿化过程中,移栽后的银杏易出现不发芽或者叶片较小的现象。本文通过研究得出结论:冬季使用草绳、薄膜、无纺布三种材料,由内到外缠绕至银杏树干4m高处进行防寒、防风及保水处理,春季(4月下旬)采用拆除无纺布、薄膜每隔50cm进行透气处理,同时每天喷湿草绳保湿的办法,可以促进移栽银杏及时发芽,且确保展叶多、叶片大。叶片发育至正常大小时,可停止喷湿草绳。同时,本文介绍了移栽银杏的生长期养护方法,以期为日后银杏在北京地区更好地应用提供一定的养护借鉴。 Ginkgo bilola L.is used popularly in Beijing. It's with beautiful and colorful leaves and with high ornamental value. However, it always accelerate late or with small leaves after transplant. It is studied that winding the trunk of Ginkgo bilola L. with straw ropes, thin film and non-woven fabric to the height of 4 meters can prevent the cold and wind in winter, and also can reserve the water of trunk. And removing the non-woven fabric in spring (late in April) , tearing the thin film every 0.5m to be ventilated and wetting straw rope every day can accelerate germination and spread leaves. The wetting of straw rope can be stopped when the leaves is as big as normal ones. Meanwhile, maintenance methods in the growing period is introduced. It is hoped that some maintenance reference will be provided.
