银杏在绿化应用中存在的主要问题及对策

Main Problems and Countermeasures in the Application of Ginkgo in Afforestation

银杏是世界上最古老的树种之一,远在两亿七千多万年前,银杏的祖先就开始出现了。和当时遍布世界的蕨类植物相比,它还是高等植物。到了一亿七千多万年前,银杏已经和当时称霸世界的恐龙一样遍布世界各地。在冰川运动时期,绝大部分银杏像恐龙一样灭绝了,只在我国部分地区保存下来为数不多的树种,流传至今,已成为稀世之宝。在当代,银杏作为重要绿化植物,被广泛应用于城市行道树栽培和园林植物造景工作中。本文将简单介绍银杏的生理特征,系统分析银杏在绿化应用中存在的主要问题,并综合探讨解决对策。

Ginkgo biloba is one of the oldest tree species in the world,more than 270 million years ago,the ancestors of Ginkgo biloba began to appear.It was a higher plant than the ferns that were all over the world at the time.By more than 170 million years ago,ginkgo was as ubiquitous as the dinosaurs that ruled the world.During the glacial movement,the vast majority of ginkgo went extinct like dinosaurs,and only a few tree species were preserved in some parts of China,which has become a rare treasure.Nowadays,ginkgo biloba is widely used in urban street tree cultivation and garden plant landscaping as an important greening plant.This paper will briefly introduce the physiological characteristics of ginkgo biloba,systematically analyze the main problems existing in the application of ginkgo biloba in greening,and comprehensively discuss the solutions.
