摘　　要：以现有5种主要印楝(Azadirachta indica)林农复合模式为研究对象,对5种主要印楝农林复合模式的印楝生长情况以及经济效益进行研究,探讨印楝与其它物种搭配种植对印楝生长结实的影响及其经济效益。结果显示:与印楝纯林相比,印楝与其它物种搭配种植不会显著抑制印楝生长结实,同时提高单位面积的经济效益;以净现值进行比较,5种林农复合模式经济效益从高到低排序为印楝-辣木间作>印楝-咖啡间作>印楝-甘蔗间作>印楝-玉米间作>印楝-木薯间作。Taking five main agroforestry patterns of neem(Azadirachta indica)as research objects,the effects of five agroforestry patterns on growth status,yield and economic benefits,including relationship between neem and under crops,were studied by comparison of different patterns.The results indicated that agroforestry patterns didn’t exert significant influence on growth of neem.Neem trees planted in agroforestry patterns improved economic benefits of unit area.By comparision of net present value(NPV)in five patterns,the order of five economic benefits of agroforestry patterns was neem-drumstick tree intercropping>neem-coffee intercropping>neem-sugarcane intercropping>neem-maize intercropping>neem-cassava intercropping.
