%X Field experiment with several coupled fertilization and irrigation treatments was conducted in State Experimental Station of Agro-Ecosystem in Fengqiu.Effect of fertilization and irrigation on wheat-maize yield,distribution of nitrate nitrogen in soil profile and the risk of nitrate nitrogen leaching under wheat-maize rotation system was studied.The results indicated that reasonable combined application of nitrogen and phosphorus fertilizers was the key to improve crop yield under appropriate irrigation rat...
