茶园害虫生态调控体系的研究

Bionomics System for Controlling Pest in Tea Plantation

通过与茶树间作、带作或周围栽培果树、药材、桑树等乔木 ,茶蓬下地表种植食用菌 ,地下种植天麻等物种 ,改善了茶园生态环境 ,为天敌提供了繁衍生息的适宜生态条件和充足猎物 ,促进了天敌良性发展。人工群落茶园内天敌数量比纯茶园增加 4 0 .6 3%～ 6 2 .72 % ,种类增加 37.5 3%～ 5 5 .4 1% ,使叶蝉、螨类、蚧类数量下降 4 0 %～ 80 % ,茶园农药使用量减少 4 0 %～ 5 0 % ,生态系统得以改善 ,向无公害化、绿色化、有机化发展。

Intercropping or strip cropping fruit tree, medicinal materials, mulberry etc in tea plantation, and planting edible mushroom, and the tuber of elevated gastrodia etc on the ground and tea shed, improved the ecological condition of tea plantation, and provided adaptable circumstance to breed abundant food for natural enemy. Natural enemies in artificial community of tea plantation increased by 40.63%～ 62.72% than usual, and the types increased by 37.53%～55.41%. As a result, quantity of leafhopper, spider mite, decreased by 40%～80%, dosage of pesticide reduced by 40%～50%.
