摘要
植物园在引种驯化过程中存在的病虫害问题是：病虫随植物的引种大量带入园区，且严重为害，造成很大损失；生境的改变及栽培管理的不当使植物的抗病虫能力下降；农药的过分使用，造成环境污染，病虫抗药性的产生及对有益生物的大量杀伤，破坏了自然界的生态平衡。防治对策提出了加强植物检疫及栽培管理、利用生物防治、合理使用化学农药等措施。
New pests were carried,seriouse injury and damage were caused,plants resistancewere decreased by unsuitable cultivation managements,environment pollution and pesticide resistance were induced by using too much chemical,lot of natural enemy werekilled and ecological equilibrium were broken,these were the problems of plant introduction and acclimatization. On the solving of these problems,plant quarantine and cultivation management should be enhenced,biological control and proper pesticide should beapplied.
