本文简述了上海地区北美槭树大苗的引种推广及其风险性,红花槭、挪威槭及杂种元宝槭等北美色叶乔木大苗在引种推广过程中均存在风险性,红花槭类及挪威槭类品种感虫,杂种元宝槭类品种抗虫。光肩星天牛和星天牛等害虫是北美色叶乔木的重要毁灭性害虫,风险性极高。提出了北美槭树引种推广中的风险性控制策略:对两种星天牛采取“成虫为主,幼虫为辅”的控制方法;合理集中群植便于日常的养护管理及其主要病虫害控制;利用复叶槭对两种星天牛的诱集性人工抓捕成虫;3种不同类型的北美槭树其主要病虫害的控制方法也有所差异;引种推广北美槭树的抗虫品种以及加强国内槭树资源的选育开发利用。
This article briefly introduced the popularization and risk of maple seedlings in North America in Shanghai. The North American colored tree seedlings such as Maple, Norway maple and hybrid maple were both risky in introduction and popularization. The red maple and Norway Acer species insects, hybrids Acer indica varieties insect-resistant. Pests such as Haliotis buraconi and Stellate beetle are important devastating pests of North American shady trees with high risk. Proposed a North American maple introduction and promotion of risk control strategy: the two aster beetles take “adult, larvae supplemented ” control method; reasonable concentration of plants facilitate routine conservation and management and its main pest and disease control ; The use of Acer palmatum to two kinds of sessile Artemia trapping adult trapped; three different types of North American maple tree its main pest and disease control methods are also different; introduced to promote the North American maple tree insect-resistant varieties and to strengthen the domestic Selection, Development and Utilization of Maple Resources.
