摘要
当前烟草种植过程中大量施用农药,但烟草病虫害非但没有得到稳定控制,反而日渐猖獗,烟田环境污染加剧。为保证烟草生产持续健康稳定发展,该文论述了生物多样性对烟田生态系统中病虫害及其天敌群落的影响,提出了利用生物多样性持续有效控制烟田害虫的方法和措施,并在此基础上开展以保护和提高烟田生态系统多样性为中心的烟草害虫生态调控机制的探讨。分析了利用生物多样性进行未来生物防治的发展方向以及对保护生态及防治虫害的重要现实意义。
Based on the fact that when applied more pesticide during tobacco planting, there was little effects on the tobacco pests, however they were becoming much more, and the pollutions were more serious. To insure the tobacco productivity could develop in a better way, the effects of biodiversity on the pests and their enemies in the Tobacco-ecosystems were addressed, and so bring forward and discuss the eco-management technique for controlling tobacco insects based on the focus of reserving and improving the biodiversity of tobacco-ecosystems. The major signification of using biodiversity to protect the environment and prevent pests and the future direction on this aspect were also analyzed.
