The irrigation effects on water consumption characteristics and nitrogen distribution and utilization in wheat plants at different nitrogen application rates in the high\|yielding conditions were studied. Four treatments of nitrogen levels were set: 0 kg hm-2（N0）, 120 kg?hm-2（N1）, 210 kg?hm-2（N2）, and 300 kg?hm-2（N3）; and four irrigation rates were set under each nitrogen level: no water (represented as W0), basal + jointing water (W1), basal + jointing + anthesis water (W2), basal + jointing + anthesis + filling stage water (W3), at 60mm every time. The results show that: (1) On W0 conditions, the water consumption amount (WCA) per day of N0 treatment during the period from jointing to anthesis was higher than those during other periods, the WCA per day of N1 treatment during the period from jointing to anthesis had no significant difference from those during the period from anthesis to maturity. At the same nitrogen application rate, the total WCA, module index, WCA per day after anthesis and the yield were increased as the irrigation rate increased, but the yield was decreased as more water was irrigated at the middle of filling stage. (2) At the same nitrogen application rate, soil water content in 20—140 cm soil layer of W1 treatment at maturity was lower than those of W2 and W3 treatments, but that in 140—200 cm had no significant difference from that of the W2 treatment. Soil NO3\|N content in 0—40cm soil layer of W1 treatment at maturity was higher than those of W2 and W3 treatments, whereas that in100—140 cm soil layer was lower than those of W2 and W3 treatments; the amount and the percentage of nitrogen distributed in vegetative organs of W1 were lower than those of W2 and W3, but those distributed in kernels were higher relative to W2 and W3. It was showed that irrigation at pre\|sowing and jointing promoted the absorption and utilization of water from 20-140cm soil layer, reduced soil nitrate leaching below 100 cm soil layer, and increased the nitrogen redistributed from vegetative organs to kernels, water/nitrogen\|use efficiencies. (3) In the experiment, with irrigation at pre\|sowing and jointing and nitrogen application at 210 kg?hm-2 rate, the highest yield and greater water/nitrogen\|use efficiencies would be achieved.
