为探讨间作对于茶园昆虫群落多样性和群落结构的影响,遂于皖南山区石台县选苦李-茶、山茱萸-茶、板栗-茶间作茶园,邻近每类间作茶园、选择相同品种和同样立地条件的纯茶园作为对照,2007年1月-2009年1月,每月上旬调查这6块茶园昆虫、蜘蛛和捕食螨种数和个体数。结果表明:①与对照茶园相比,间作茶园昆虫的总物种数、总多样性指数稍大,间作茶园的天敌个体数稍多、益害生物的个体数量比值稍大;②间作对茶园昆虫的总个体数有影响。结果表明茶园间作可在一定程度上增加昆虫多样性。
In order to explore the effect of intercropping on the diversity and community structure of insect community in tea plantation, tea plantation was selected from Bitter Li - tea, Cornus officinalis - tea and chestnut - tea plantation in Shitai county of mountainous area in southern Anhui Province. Adjacent to each type of intercropping tea plantation, Conditions of the pure tea garden as a control, January 2007 -2009 January, early January each month to investigate the six kinds of tea plant insects, spiders and predatory mites species and the number of individuals. The results showed as follows: ①Compared with the control tea plantations, the total number of species and total diversity index of tea plantation intercrops slightly larger, the number of natural enemies of intercropping tea plant slightly more, and the ratio of individual number of beneficial organisms slightly larger; The total number of individuals has an impact. The results showed that the intercropping of tea plantations can increase the insect diversity to a certain extent.
