摘    要:本文研究了甘肃省河西走廊麦田不同种植模式农田水分利用效率及相应的干物质积累动态、籽粒产量、经济效益和能量产出各指标。结果表明:春小麦孕穗、抽穗期是提高春小麦农田水分利用效率的关键期。春小麦与玉米、马铃薯、甜菜套种农田水利效率高于单种春小麦;河西走廊区麦田节水型高产种植模式主要是春小麦/玉米,春小麦/马铃薯,节水高效模式主要是春小麦/马铃薯和春小麦/甜菜。

关 键 词:春小麦,种植模式,农田水利利用效率

Abstract:The water use efficiency,the dry nntter accumulation,seed yield,economicefficiency and energy output of different cropping potterns in spring wheat field were investigutedin the Hexi corrido,Gansu provincle The investigation revealed that the highest yield and energyout were obtained when the pottern of spring wheat relay-cropping with corn was enployed.whereas the highest income was achieved when the pottern of spring wheat intercropping withpotato or sugarbeet was used. The adaptive cropping pattern in spring wheat field was the potternof spring wheat relaycropping with corn. spring wheat /potato intercropping and spring wheat/sugurbeet intercropping in their given order.
Keywords:Spring wheat Cropping pettern Water use efficiency
