摘要
为实现枣树有害生物的生态调控,采用系统调查方法,对太谷地区不同管理模式下枣园的不同功能团节肢动物群落进行了调查和分析,同时也探讨了枣园不同管理类型条件下生物的多样性与稳定性的关系。结果表明,常规枣园的各功能团节肢动物物种数显著低于苜蓿枣园,而节肢动物群落的个体优势度显著高于苜蓿枣园;苜蓿枣园的节肢动物各类群的多样性和均匀度明显高于常规枣园;枣草间作既可增加枣园生态环境的复杂性,又可维持枣园生态系统的稳定性。
To control pests,studies on the dynamics of arthropod communities in the jujube yard under different management were conducted in Taigu county.The results showed that in jujube yard with alfalfa there were more arthropod species of various communities than in the conventional jujube yards,while there were more individual dominance index in the jujube yard without alfalfa than in the conventional jujube yards.The diversity index and evenness of arthropod in the jujube yard with alfalfa were markablly higher than those in jujube yard without alfalfa.Simultaneously,the relationship between the diversity and stability of arthropod communities under different management method was also analyzed.In addition,intercropping in jujube yards was not only more beneficial to increase diversity and evenness of beneficial insects,but also to increase unit area yields.
