复合间作栽培模式对茶园节肢动物群落的影响研究

对复合茶园和单一茶园中节肢动物的群落进行调查、分析和比较。结果表明,复合茶园和单一茶园相互间物种的数量组成差异较大,复合茶园生态系统的生物多样性比单一茶园丰富、稳定。因此茶园禁用农药且茶园中植物相丰富,形成荫蔽环境,有助于涵养天敌,增加蜘蛛等天敌数量和种类。

Effects on arthropod communities under multiple intercropping cultivation model in tea garden

Investigation, analysis and contrast of arthropod communities had been processed between multiple tea garden and simple tea garden. The result showed that the difference of species number was remarkable between two kinds of tea garden. The biology species of compound tea garden had more bio-diversity and stability than the single ecosystem of tea garden. So forbidding pesticide could make the species abundant and induced environment of shading which would help the insects such as spiders nursing and protect...
