以冬小麦为试验材料,研究了2012—2014年宽垄灌溉方式对冬小麦的耗水特性及产量的影响。结果表明,不同水分处理对冬小麦的耗水量及产量产生较大影响。2012—2014年宽垄灌溉方式下冬小麦产量提高了611.7-1 399.8kg/hm^2,水分生产效率增加了7.56%-17.07%。宽垄灌溉和常规灌溉方式下,冬小麦产量与耗水量呈良好的抛物线关系。当耗水量为499.35mm时,宽垄灌溉的产量比常规灌溉时提高了938.22kg/hm^2。水分过高或过低均会抑制冬小麦的正常生长,当水分控制下限为田间持水率的70%时,有利于实现冬小麦节水高产。
Taking Winter wheat as experimental material,the effects of wide ridge irrigation on winter wheat water consumption characteristics and yield were studied from 2012 to 2014.The results showed that the different water treatments had great influences on water consumption and yield of winter wheat.The yield of winter wheat increased by 611.7-1 399.8kg/hm^2,the water production efficiency increased by 7.56% -17.07% in wide ridge irrigation over 2012—2014;There were good parabolic relations between water consumption and yield of winter wheat under wide ridge irrigation and conventional irrigation.Compared with the conventional irrigation,the yield of winter wheat under wide ridge irrigation increased by 938.22kg/hm^2 when the water consumption was 499.35 mm.Too high or too low water would inhibit the normal growth of winter wheat,when the control limit of moisture was 70% of field capacity,it was conducive to achieve high yield and water saving of winter wheat.
