茶园间作对病虫害防控效应与作用机制研究进展

茶园间作作为病虫害综合治理的一项措施,对农药减量使用与茶叶绿色安全生产具有重要意义。合理间作可改善茶园小气候、优化天敌生存条件、提高生物多样性,使物种间构成复杂的食物链和食物网,从而加强对病虫害的控制,降低其暴发风险。此外,部分植物可干扰昆虫种群活动,选择性间作可达到吸引天敌及毒杀、驱避或诱集害虫等目的。本文综述了茶园间作对茶树病虫害防控效应的影响及作用机制研究进展,展望了今后利用间作生态治理茶园病虫害的研究方向。

Research Progress on Control Effect and Mechanism of Intercropping on Diseases and Pests in Tea Garden

As a measure of integrated pest management,intercropping in tea garden is of great significance to reduce the use of pesticides and green and safe production of tea.Reasonable intercropping can improve the microclimate of tea garden,optimize the living conditions of natural enemies,enrich the biodiversity,form a complex food chain and food web among species,and thus strengthen the control of pests and diseases and reduce the risk of outbreak.In addition,some plants can interfere with the activities of insect population,and selective intercropping can attract natural enemies and poison,repel or trap pests.In this paper,the research progress on the effects of intercropping in tea garden on the control of tea plant diseases and pests and its mechanism were reviewed,and the research direction of using intercropping to control tea garden diseases and pests in the future was prospected.
