摘　　要：在甘肃河西绿洲灌区，对春小麦在垄作和平作两种栽培方式下的产量和水分利用效率进行了对比研究，结果表明，垄作栽培方式有较好的增产、节水、增温效应，与对照平作栽培相比，5～10cm土层地温提高1．41℃；在相同的灌溉定额下，春小麦千粒重增加2．45～3．31g，穗粒数增加5．33～8．02粒，增产471～1371kg／hm^2，水分利用效率提高0．6～4．7kg／（mm·hm^2），垄作栽培条件下春小麦适宜灌溉定额为360mm，与对照相比，节水75mm，与当地大田灌溉定额540mm相比，节水180mm，节水效果十分显著。In the irrigated area in Hexi Oasis of Gansu, the yield and water use efficiency of spring wheat is studied by the cultivation methods of raised bed planting and flat planting. Results show that the raised bed planting cultivation method possesses better effectiveness of increasing the yield of spring wheat , and soil temperature. Compared with the flat planting method , soil temperature of 5-10 cm soil layer raised 1.41℃, When the irrigation water volume is the same, athousand-grain weight and seeds per spike of spring wheat increased by 2. 45-3.31 g and 5. 33-8. 02 respectively, and the yield increased by 471-1 371 kg/hm^2 , water use efficiency increased by 0. 6-4. 7 kg/（mm · hm^2） , Under the circumstance of raised bed planting, the suitable irrigation water volume for spring wheat is 360 mm. Compared with the irrigation water volume of 540 mm for local farmer field , 180mm water was saved, the water-saving effect is very obvious.
