在对安徽省祁门县七里桥茶厂茶园捕食性天敌群落进行系统调查的基础上,采用极点排序分析方法,研究了茶园捕食性天敌群落的动态分类,采用主成分分析方法,研究了茶园捕食性天敌群落在茶树生长发育过程中的演替。结果表明,茶园捕食性天敌群落的时序动态可以分为6种类型,演替可以分为形成和发展阶段、鼎盛阶段和衰退阶段3个主要阶段。研究结果为科学制订茶树不同生育期害虫防治策略和综合治理措施提供了重要依据。
Based on the systematic investigation of the predatory natural enemies in the tea plantation of Qiliqiao tea plantation in Qimen County, Anhui Province, the dynamic classification of predatory natural enemies community in tea plantation was studied by using the pole ordering analysis method. Principal component analysis was used to study the predation of tea plantation Succession of sexual natural enemy communities in tea tree growth and development. The results showed that the temporal dynamics of the predatory natural enemy community in tea plantations can be divided into six types. The succession can be divided into three main stages: formation and development stage, heyday stage and recession stage. The results provide an important basis for scientifically formulating the prevention and control strategies and comprehensive control measures for tea in different growth stages.
