摘　　要：为探讨绿肥植物对咖啡园节肢动物功能团多样性的影响,分别于2021年7月和11月采用目光搜寻法对常规种植(CK)、大翼豆种植(ML)、新诺顿豆种植(NW)3种类型咖啡园的节肢动物群落进行了调查,分析了各功能团的多样性和群落稳定性。结果表明:在常规种植咖啡园采集到节肢动物22种161头,大翼豆种植咖啡园采集节肢动物34种108头,新诺顿豆种植咖啡园采集节肢动物27种101头。绿肥种植模式咖啡园各功能团的Margalef、Shannon-Wiener、Pielou指数均高于常规种植咖啡园捕食性功能团的,而常规种植咖啡园天敌功能团的Simpson指数显著高于绿肥种植模式咖啡园各功能团的;绿肥种植模式咖啡园节肢动物群落的Ss/Si和Sa/Sp指数均高于常规种植咖啡园的。典型对应分析表明,绿肥种植模式咖啡园捕食性节肢动物的物种数和个体数更多;绿肥种植模式咖啡园节肢动物群落的稳定性更高,天敌与植食性害虫的相互制约关系更明显,更有利于有害生物的绿色防控。In order to explore the effects of green manure on the diversity of functional arthropod groups in coffee orchards,the investigation of arthropod communities was conducted by searching methods in three types coffee orchards in July and November 2021(CK:Conventional planting coffee orchards;ML:Coffee orchard with green manure Macroptilium lathyroides;NW:Coffee orchard with green manure Neonotonia wightii),and the diversity and community stability of each functional group were analyzed.The results showed that a total of 161 arthropod individuals were collected from the coffee orchard CK,representing 22 species,108 arthropod individuals were collected from the coffee orchard ML,representing 34 species,and 101 arthropod individuals were collected from the coffee orchard NW,representing 27 species.The Margalef index,Shannon-Wiener index and Pielou index of functional arthropod groups in coffee orchards planted with green manure were higher than those of the functional predatory groups in the coffee orchard CK,while the Simpson index of the functional predatory groups in the coffee orchard CK was significantly higher than that of functional arthropod groups in coffee orchards planted with green manure.The Ss/Si index and Sa/Sp index of arthropod community in coffee orchards planted with green manure were higher than those in the coffee orchard CK.Canonical correspondence analysis shows that the species and individuals of predators is higher in coffee orchards planted with green manure.The arthropod community is more stable,and the relationship between predators and herbivorous pests is more obvious,which is more conducive to the green prevention and control of pests in coffee orchards planted with green manure.
