中文摘要	研究了绿洲灌区垄作沟灌栽培条件下土壤温度和水分的变化及对春小麦的产量和水分利用效率的影响。结果表明,垄作沟灌栽培条件下,0~25cm土层土壤温度日变化以16:00差异最为显著,春小麦拔节前0~10cm平均土壤温度较平作栽培提高1.41℃,并随春小麦生长发育进程的推进,增温效应逐渐弱化。对深层土壤水分的消耗减少,0~20cm土壤含水率低于平作栽培,而20~80cm土壤含水率高于平作栽培。与平作栽培相比,相同灌溉定额下产量增加7.18%~34.97%,水分利用效率提高9.42%~27.34%,节水750m3/hm~2。
英文摘要	Changes of soil water and temperature and yield effects of raised bed planting spring wheat were studied in Hexi oasis area.The results showed that the differences of soil temperature between raised bed planting and flat planting were biggest at 16:00 for daily changes.The average soil temperature in 0~10 cm layer increased by 1.41 ℃ before wheat elongation and its increasing effects were reduced as wheat growing.The soil water consumption from deeper layer were reduced,the soil water content was lower in 0~20 cm and higher in 20~80 cm than flat planting.Under same irrigation the yield increased 7.18%~34.97%,WUE increased 9.42%~27.34% and irrigation water saved 750 m3/hm~2.The effects of water-saving,soil temperature and yield increasing were remarkable for spring wheat.
