摘　　要：在杏-麦间作果园分别套种油菜、芜菁和紫花苜蓿三种蜜源植物,并对果园节肢动物群落参数值进行分析。结果表明,三个种植蜜源植物的果园天敌亚群落的物种多样性指数和均匀度指数均高于对照果园,而害虫亚群落的物种多样性指数和均匀度指数均低于对照果园。三种蜜源植物均能增加果园生物多样性,提高果园生态系统的稳定性。三种种植了蜜源植物的果园中,捕食性天敌草蛉的数量分别比对照增加了134.8%、34.8%和103.7%;瓢虫类的数量分别增加了100%、161.8%和70.9%;并且新增了大眼长蝽、粉蛉和黑缘红瓢虫三种天敌,在一定程度上抑制了害虫的发生。The investigation of the parameters of arthropod community in orchards was carried out when the three kinds of honey plants such ass rape, turnip and alfalfa were interplanted between apricot and wheat. The results showed that the species diversity and evenness of natural enemies in sub - community is higher than the control orchard,and the species diversity and evenness of pest insects in sub - community is lower than the control orchard. The Honey plants can increase the species diversity and improve the stability of the orchard. The number of the Chrysopidae in test orchard increased by 134.8 %, 34.8 % and 103.7 % ; and the number of the coccinellidae in test orchard increased by 100%, 161.8% and 70.9%. The three natural enemies Geocoris pollidipennis （Costa）, Chilocorus rubidus Hope and Coniopterygidae were newly increased, which restricted the occurrence of the inseet pests..
