摘　　要：通过带型、品种和种植方式组合筛选了适于绿洲灌区应用的"高产高效"种植模式,研究了不同模式的生产能力和生理生态特性。结果表明,小麦/玉米‖洋芋(-洋芋)和新型小麦/玉米模式具有明显的增产作用,三大模式平均产量高于传统"吨粮田"11%,其中"三种三收"模式增产增效更为显著,推广价值较高。试验同时得出影响复合群体产量的因子顺序是小麦品种>玉米品种>种植方式,组分产量的突破口主要在生理特性方面。参试模式中最优组合是A3B1C3。表5,参3。Multiple intercropping patterns with different proportions,varieties and plant patterns were combined to select a high yield and high efficiency pattern for oasis irrigation area of Hexi Corridor,and the productivity and phys-ecological characteristics of different patterns were researched in this paper.The result showed that,wheat/corn and wheat/corn||potato(-potato) could improve the yield significantly compared to the control,the average yield of the multiple cropping patterns is 11% higher than the 'Dunliang',and the cropping patterns of wheat/corn||potato(-potato) showed the most significant yield increase effect,and valuable to extent.The serial of the factors which affected the yield of intercropping was wheat variety> corn variety > plant pattern,the yield breakthrough of the intercropped crops was the characteristic of physiology.The A_3B_1C_3 was the optimum cropping pattern for oasis irrigation area of Hexi Corridor.
