Title: Effect of Optimum Nitrogen Fertilization on Grain Yield and Nitrogen Use Efficiency of Wheat and Maize by High-yielding Intercropping
Abstract: The experimental results showed that the optimum fertilization could increase the grain yield and nitrogen use efficiency,and save N fertilizer by 38.96%~46.12%.As the soil fertility increased,the increase of grain yield was more steady.Optimum fertilization could reduce the accumulation and loss of soil nitrate nitrogen and protect the groundwater and environment.
