不同类型茶园捕食性天敌群落相似性研究

采用群落种组成相似性分析、群落组成相似性分析和群落特征相似性分析3种方法,研究了祁红产区等高茶园、平地茶园和坡地茶园3种茶园类型及春茶、夏茶和秋茶3个生育期捕食性天敌群落的相似性。结果表明,群落种组成相似性平均水平的排序为不同类型茶园相同生育期>不同类型茶园不同生育期>同一类型茶园不同生育期>同一类型茶园相邻生育期。坡地茶园秋茶、平地茶园夏茶和秋茶以及等高茶园秋茶的群落组成最为相似;而平地茶园和坡地茶园春茶次之。等高茶园和平地茶园春茶的群落特征最相似,其次为3种类型茶园秋茶及平地茶园夏茶。

Similarity of Predatory Enemy Communities of Different Tea Plantation Types

In this paper, three methods, namely, community species composition similarity analysis, community composition similarity analysis, and community characteristic similarity analysis, were employed to study the similarity of predatory enemy communities of three tea plantation types (contour , flat and sloping) and their three development stages (vernal tea stage, estival tea stage and autumnal tea stage) in Qimen county of Anhui province. The results showed that the average levels of community species composition similarity were in order of the same development stages of the different tea plantation types>the different development stages of different tea plantation types>the different development stages of the same tea plantation types>the adjacent development stages of the same tea plantation. The community compositions of the autumnal tea stage of contour and sloping tea plantations were the most similar to that of both estival and autumnal tea stages of flat tea plantation, and the autumnal tea stage of flat tea plantation to the autumnal tea stage of sloping tea plantation secondly. The community characteristics of the vernal tea stage of contour tea plantation and flat tea plantation were also the most similar and the autumnal tea stage of three tea plantation types to the estival tea stage of flat tea plantation secondly.
