Abstract：InordertomakeeficientuseofwaterandfertilizerinputsforwheatintheplainareaofHebeiProvince，fourcultivation management patterns were setup，including treatment A（customary management oflocalfarmers：N appication rate of 266kg/hm2 ， P205 of 200kg/hm2 ，with a total irrigation amount of 300mm ），treatment B（recommended management of high yield：N application rate of 220kg/hm2 ， P205 of 152kg/hm2 ，KOof 150kg/hm2 ，with a total irrigation amount of 195 mm），treatment C（high input management of water and fertilizer：N application rate of 300kg/hm2 ， P205 of 225kg/hm2 ，KO of 300kg/hm2 ，with a total irrigation amount of 270mm ），and treatmentD（eficient management of water and fertilizer：N application rate of 270kg/hm2 ，PO5 f184kg/hm2 KOof 270kg/hm2 ，with a total irrigation amount of 215mm ），and the optimal cultivation pattern was determined by measuring the yieldandutrientutilzationeficiencyTeresultsshowdthattheyieldsoftreatmentCandtreatmentDweresignificantlyigerthan those of treatment A（ P <0.05），reaching 9 881 kg/hm² and 10360kg/hm2 ，respectively，which increased by 20.2% and 26.0% compared withtreatmentA.The nutrientcontentofplantsunder treatments CandDwashigherthanthatundertreatmentsAandB，while thenutrientdemandofgaindidnotincreasealongwiththeyield.TheaccumulationofsoilnitratenitrogenundertreatmentDwas 43.15kg/hm2 ，which was lowerthan thatundertreatments Band C，indicatingthatnitrogen had been effectivelytransferred to plants andtheriskofleachingwasreduced.Consideringtheyield，waterandfertilizerinput，andevironmentalisks，itwassuggsteat the treatment D could be used as a feasible high-yield cultivation pattern.
