2种大青叶蝉防治方法的效果对比试验

Comparative Experiments on Controlling Technology of Two kinds of Cicadella viridis

大青叶蝉对宁夏灌区农田林网新植树木具有很大的危害性,化学防治和物理防治对大青叶蝉都具有良好的防治效果,能够显著降低树木抽干,提高树木保存率。从防治效果和防治效益综合来看,建议采用物理防治。

Cicadella viridis damage the newly - planted trees severely in farmland shelterbelt nets in Ningxia irrigating area. Chemical and physical methods have the outstanding controlling effect on C. viridis , which can significantly prevent tree dehydration and enhance survival index. However, physical method is better than chemical method on the aspect of the controlling cost and preventing effect.
