Abstract: Abstract: In the paper, using spring wheat variety yong liang-4. Under different irrigation treatment, we studied the influence of irrigation rate and time on water consumption and yield. The result showed that: with the increase of time and rate of irrigation, total water consumption increased, Soil water reduced. Variation of water consumption intensity is relation to water supply of that stage, the more water supplied, the larger of water consumption intensity. Analyze the yield inscape we may know, water at jointing stage can increase spick numbers and No. grain per ear. Water at booting and flowering stage can promote 103 grain weight. The WUE that: 2 water treatment>3 water >4 water>1 water>ck. And with the increase of time and rate of irrigation, wheat yield also increase. That yield difference is not evidence 2 waters and 3 water’s treatment with 4 water, but water consumption reduced, it would achieve the source-sink of saving—water with high yield. Irrigation in the stage of booting and a thesis is efficient in spring wheat.
