Winter wheat LAI,shoot biomass,yield and soil water use efficiency were studied in Huantai,Shandong Province,at four doses of nitrogen applications(0、100、200、300 kg·hm-2),under both drip and flooding irrigations.The results showed that winter wheat leaf area index(LAI),shoot biomass,yield were not obviously affected by the two water managements.Soil water using efficiency was in a range of between 1.16 and 1.34 kg·m-3,revealing that in comparison with drip irrigation,the flooding irrigation accelerated soil...
