  Nitrogen rates at 120 and 240 kg/ha significantly increased the yields and water use efficiency of winter wheat and summer maize compared to the no nitrogen fertilizer treatment,but the differences between the two nitrogen rates(N120 and 240 kg/ha)was not significant.

  与未施氮肥相比,施氮N 120和240 kg/hm2显著提高了玉米、小麦的产量和水分利用效率,但两施肥处理间产量和水分利用效率差异不显著。
