指出了杨树作为河西走廊地区重要的防风固沙树种,在区域生态经济发展上占有重要地位,对于实现当地生态效益和经济效益共同提高具有重要的意义。但是,大青叶蝉作为河西走廊地区多种林木及农作物的主要害虫,严重影响了杨树的正常生长及木材质量,为此对杨树大青叶蝉的发生原因进行了探讨,并就发生现状提出了综合防控策略,为从根本上增强林木病虫害综合防控能力提供一定的技术参考。

As an important wind and sand-fixing tree species in the Hexi Corridor area,poplar occupies an important position in the development of regional eco-economics,and is of great significance for the improvement of local ecological and economic benefits.However,as the main pest of various forest trees and crops in the Hexi Corridor area,the large green leafhopper severely affects the normal growth and wood quality of poplars.For this reason,this paper discusses the causes of the large green leafhopper and its occurrence.Comprehensive prevention and control strategies are put forward to fundamentally enhance the comprehensive prevention and control of forest diseases and insect pests to provide a certain technical reference.
