在太谷地区枣麦间作与枣单作生态系统中,研究了综合防治与常规防治对枣树不同发育阶段的节肢动物群落、害虫亚群落和天敌亚群落多样性的影响。结果表明在各个发育阶段,4种不同处理中的枣园节肢动物群落、害虫亚群落和天敌亚群落的多样性指数均存在显著性差异(P<0.05);通过对影响枣园生态系统3种多样性指数的因子的方差分析表明,枣麦间作和综合防治措施的共同作用是影响枣园生态系统节肢动物群落和天敌亚群落多样性指数的主要因子。
In the Taigu Valley Zaokou intercropping and jujube monocotyledon ecosystem, we studied the effects of integrated control and conventional control on the diversity of arthropod community, pest sub-community and natural enemy sub-community in different developmental stages of jujube trees. The results showed that there were significant differences in the diversity index of arthropod community, pest sub-community and natural enemy sub-community in jujube orchard in four different treatments at all developmental stages (P <0.05) Analysis of variance of the factors of diversity index showed that the interaction of Zaoyi intercropping and comprehensive control measures was the main factor affecting the diversity index of arthropod community and natural enemy sub-community in Zaoyuan ecosystem.
