摘要
为利用生物多样性控制害虫及筛选抗虫茶树品种提供依据,以广东省农业科学院茶叶研究所品种园内6种典型茶树品种资源为试验材料,采用平行跳跃法对不同茶树品种节肢动物群落组成、差异进行研究。试验结果表明:各个茶树品种节肢动物群落的组成、多样性虽有相似性,但不同茶树主要天敌与害虫、多样性指数的动态趋势、茶丛不同层次的节肢动物类群等是有差异的。其群落天敌个体数与害虫个体数的比值最高品种为‘乐昌大叶白毛’;节肢动物多样性指数与优势度指数平均值较大品种是‘云大淡绿’。茶丛上层的群落多样性指数相对较高,茶丛不同层次节肢动物多样性存在着差异。‘云大淡绿’‘英红10号’等茶树的茶丛上层物种数较多;在茶丛的下层,节肢动物多样性指数最多品种是‘碧云’。
For use of biodiversity control insects and screening of tea varieties to insects carry the basis,six typical tea varieties in Tea Research Institute of Guangdong were choose as test materials to investigate the breed jumping arthropod community composition with a parallel method.The results showed that each tea varieties of the arthropod community composition,diversity was similarities,but the main predators and pests of tea,the dynamic trend of diversity,different levels of arthropod groups were different.The ratio of the maximum number of individuals and their communities‘pest predators’was‘Lechangdayebaimao’,both the highest arthropod of diversity index and dominance index average were‘Yundadanlu’,with the arthropod of more diversity and richness of tea plexus upper.Tea plexus different levels arthropods diversity was differences.‘Yundadanlu’and‘YingHong10’had more species in plexus upper,but arthropod species diversity index was up on‘Biyun’in the tea plexus below,.
