Abstract: In order to identify the fertilization measures which would reduce N2O emission and increase crop yield under the same level of nitrogen application,the N2O fluxes of spring corn fields in North China plain with different fertilizations（urea，nano synergism ammonium，nano synergism urea and no fertilizer）were measured using automatic sampling and analyzing system based on static chambers and gas chromatography(GC).Experiment results showed that it existed significant differences (PNA>U>CK.The corn yield increment in the treatments NU and NA were 11% and 9%(P<0.05),respectively,as compared to the treatment U.It was concluded that nano synergism nitrogen fertilizer was a better practice to reduce N2O emission with significant yield increment.

Key words: Nano synergism ammonium, Nano synergism urea, N2O flux, Total cumulation of N2O emissions, Mitigation
