Abstract With reference to the cumulative 20 cm diameter pan evaporation(E), a field experiment was conducted for 2 consecutive years(2012—2013)to study the coupling effects of water-nitrogen on water consumption, crop physiological indexes and yield of winter wheat under drip irrigation in the North China Plain. The results indicated that the irrigation-scheduling had significant effects(at 0.05 level)on water consumption, LAI and wheat yield. In a nitrogen application range of 120 to 290 kg/hm2 with drip irrigation, water-nitrogen coupling effects had no significant influence on water consumption. At 140-190 kg/hm2 with irrigation level of 0.80E under drip irrigation, the yield was higher and residual nitrate nitrogen after one season was less. Furthermore, significant increasing in irrigation level and nitrogen level would lead to significant decline in wheat yield. Referring to guarantee yield and low environmental contamination risks, an optimized water-nitrogen combination, irrigation level of 0.80E with nitrogen application of 140-190 kg/hm2, was recommended under drip irrigation in the North China area.
