中文摘要	基于田间试验,分析了水平畦灌条件下不同灌溉制度对土壤水分、油葵生长生理指标、产量及水分利用效率(WUE)的影响。结果表明,油葵生育期内灌溉计划湿润层为0~40cm时,可满足其水分需求;在2012年生长季降雨量较大(247mm)的情况下,较低灌水定额对作物的生长生理指标并无显著负面影响;丰水年宁夏中部干旱带油葵畦灌的优化灌溉制度为灌水4次,每次灌水定额600m~3/hm~2,在保证产量的基础上,作物耗水量可降低20%以上,WUE提高约20%。
英文摘要	Based on field experiments,the effects of different irrigation water amounts on soil water content, growing and physiological factors, yield and water use efficiency (WUE) of the sunflower were studied under border irrigation. Results showed that: the irrigation wetting depth could be designed as 0~40cm to supply enough water for the growth of sunflowers.When the rainfall(247mm)was large enough in 2012,there was no obvious effect on the growing and physiological factors under the treatment of the lowest irrigation water amount. The treatment 3, in which crop water consumption decreased by 20% and WUE increased by 20% without affecting yield significantly, was recommended in arid region of Ningxia.
