The effects of irrigation methods on ammonia volatilization and wheat yield in fluvo-aquic soil were studied on the basis of a four-year field positioning experiment with different irrigation methods. A total of 4 treatments were set up，including three types of irrigation methods，i.e.，traditional irrigation(TI)，sprinkling irrigation(SI)and drip irrigation(DI)，with no fertilization and irrigation treatment as the control(CK). The results showed as follows:(1)The peak of ammonia volatilization rate of different irrigation methods in wheat base fertilizer and topdressing period appeared on the 3rd and 1st day after fertilization，respectively，and the ammonia volatilization rate of DI treatment was significantly lower than that of TI treatment during the period of high ammonia volatilization rate(the first 4 days after fertilization).(2)The total amount of ammonia volatilization，ammonia volatilization loss rate，ammonia emission coefficient and ammonia volatilization intensity per unit yield of TI were the highest in different irrigation methods，which were 3.61 kg/hm²，1.72%，1.07% and 0.63 kg/t，respectively，and the lowest in DI treatment，which were 2.98 kg/hm²，1.42%，0.77% and 0.43 kg/t，respectively，which were lower than TI treatment by 17.6%，17.6%，28.2% and 30.7%，respectively.(3)Irrigation significantly increased wheat yield by 32.0%-51.7% compared with CK，and the yield in DI treatment was the highest，up to 6.85 t/hm²，which was 57.1%，19.0% and 10.7% higher than that in CK，TI and SI，respectively.(4)Correlation analysis showed that soil water content and ammonium nitrogen content were very significantly or significantly positively correlated with ammonia volatilization rate during base fertilizer and topdressing period，while rainfall and average wind speed were only significantly or extremely significantly positively correlated with ammonia volatilization rate only during topdressing period. In summary，the drip irrigation was the best irrigation method to increase wheat yield and reduce NH₃ volatilization loss in farmland under the soil environment and meteorological conditions in this study.
