摘　　要：2010年通过大田滴灌试验,研究了不同灌水量对复播油葵耗水特性和产量的影响。在灌水次数相同的情况下,设置了4个灌水处理,灌水定额分别为30、37.5、45、60mm。试验结果表明,复播油葵全生育期耗水量,开花期>现蕾期>苗期>灌浆期>成熟期;回归分析初步得出,滴灌油葵适宜的灌溉定额范围为285.19～287.67mm。Through the field drip irrigation experiment,the influence of different irrigation quantity on water consumption character and yield of multiple seeding sunflower were studied in 2010.In the case of the same irrigation frequency,test was set 4 irrigation treatments,irrigation quota were 30 mm,37.5 mm,45 mm,60 mm.The results showed that,in the whole growing state of multiple seeding sunflower,the water consumption showed flowering stage,budding stage,seeding stage,filling stage,maturity stage.Based on the regression equation of yield,water consumption and irrigation quota,the fitting irrigation quota for sunflower was 285.19 to 287.67 mm.
