Abstract The effect of storage irrigation by no-tillage with stubble mulch on water consumption and irrigation water use efficiency of spring wheat was studied at Heihe River Center Experimental Station in Hexi Corridor. Results showed that: (1) As for the whole growing stage, compared with other tillage methods, no-tillage with stubble mulch didn't reduce soil water consumption of spring wheat but changed the spatio-temporal pattern of water consumption. (2) The mean daily water consumption under no-tillage with stubble mulch was the highest with respect to the whole growing stage, but it was the minimum with respect to the whole year because no-tillage with stubble mulch preserved much soil moisture during no-cultivation stage. (3) To obtain high yield and improve irrigation water use efficiency, the treatment of no-tillage with stubble mulch tillage with water storage of 1 200 m3\5hm-2 in winter was the best. (4) During the whole growing stage and the whole year, the mean daily water consumption increased and irrigation water use efficiency decreased when the storage irrigation amounts in winter increased. So, if only for improving water saving efficiency and irrigation water use efficiency, the storage irrigation amount in winter should be reduced to 750 m3\5hm-2.
