Fertilization critically influences soil N2O emissions. In this study, N2O fluxes and grain yields were measured in a maize field applied with a controlled-release fertilizer or anitrification inhibitor. The experiment原 was conducted in Shanxi Province,China, during 2009—2012. Four different fertilization treatments(CK: no fertilizer, U: conventional urea, SCU: sulfur-coated urea, UDD: nitrification inhibitor)were designed. Automatic static chamber-gas chromatography method was used to measure N2O emissions. Environmental parameters and maize yields were also monitored simultaneously. Compared with urea, sulfur-coated urea and nitrification inhibitor reduced cumulative N2O emissions during the 4 growing seasons, with average reduction of 37.77% and 33.39%, respectively. The grain yields of SCU and UDD treatments increased by 16.04% and 6.35%, respectively, in comparison with the urea treatment. The N2O fluxes were significantly related with 5 cm soil temperature, 10 cm soil moisture and soil NH + 4 content (P60%WFPS
