【摘要】 采用振枝法和杀虫灯检测法对湖南省长沙市高桥茶场无公害茶园和常规茶园进行节肢动物群落多样性调查,并比较无公害多种措施相结合对茶园重要害虫黑刺粉虱的控制作用。结果表明,采用行间覆草、悬挂杀虫灯和施用植物源农药集成的茶园无公害防治技术,与常规防治相比,较好地保护了茶园的天敌,提高了茶园节肢动物群落多样性,抑制了黑刺粉虱的暴发为害。表明茶园采用无公害防治技术,能使茶园节肢动物群落多样性逐渐上升,维护生态平衡,避免黑刺粉虱等少数害虫在没有农药压制的情况下暴发为害,能保证茶叶的食用安全和品质。更多还原

【Abstract】 The diversity of arthropod communities was investigated using pest-killing lamp and branch-shaking methods in Gaoqiao non-polluting tea garden and conventional tea garden of Changsha,Hunan(China) and the effects of various non-polluting control measures on spiny white fly in the tea garden were compared.The results showed that,compared to conventional control methods,the integrated non-polluting control techniques viz.,straw mulching between lines,hanging pest-killing lamp and applying plant pesticides,could protect the natural enemy of tea garden,improve the diversity of arthropods species,and restrain the damage of spiny white fly.It indicated that non-polluting control technologies could increase the diversity of arthropod communities and maintain the ecological balance,as well as restrain the damage caused by spiny white fly under the circumstance of without pesticide application,and ensure the quality and safety measures for tea.更多还原
