中文摘要	于2008-2009年,在甘肃省农业科学院张掖节水农业试验站,研究绿洲灌区春小麦垄作沟灌栽培条件下土壤物理性状的变化及其对春小麦产量的影响。结果表明,垄作沟灌栽培0~40cm土壤坚实度明显低于平作,0~20cm土壤体积质量较平作降低2.52%。0~10cm日均土壤温度较平作提高1.41℃,且随春小麦生长发育进程的推进,增温效应逐渐弱化。垄作沟灌栽培春小麦三叶期0~10cm土层质量含水量低于平作栽培,挑旗期至成熟期0~120cm土层质量含水量高于平作栽培。垄作沟灌栽培春小麦产量较平作增产7.27%~34.69%,水分利用效率提高2.37~4.71kg/(hm~2.mm),节水750m3/hm~2。垄作沟灌栽培对土壤坚实度、体积质量、温度和水分的影响是春小麦节水增产的主要原因之一。
英文摘要	To explore water-saving and yield-increasing mechanism and further to improve cultivation techniques of raised bed planting wheat,in this paper,effects of soil physical properties and yield of Raised bed planting spring wheat in Oasis area were studied.The results showed that the soil strength in 0-40 cm layer reduced and soil bulk density in 0-20 cm layer decreased 2.52% compared to flat planting.The daily average soil temperature in 0-10 cm layer increased 1.41 ℃ and the difference between raised bed planting and flat planting decreased as wheat growing.Soil water content in 0-10 cm layer was decreased than flat planting before 3-leaf stage but it is increased in 0-120 cm layer than flat planting from flag stage to mature.Compared to flat planting,the yield was increased by 7.27%-34.69%,WUE was increased by 2.37-4.71 kg/(hm~2·mm) for raised bed planting and 750 m3/hm~2 irrigation water can be saved.The influences on soil strength,soil volume mass,soil temperature and soil water were one of key reasons why the yield increased for spring wheat under raised bed planting.
