During the growth period of summer maize, fresh water (F) and reclaimed water (R) are both used for drip irrigation with no fertilizer (CK), urea (U), ammonium sulfate (A) and slow-release urea (S). From the result of experiment, we can realize the impact of different water quality and different nitrogen fertilizers on CO2 and N2O emissions from the soil and the yield of summer maize. The result showed that the average daily emissions of CO2 flux from the soil irrigated by reclaimed water is reduced by an average of 12.44%, and the average daily emissions of N2O flux from the same soil was increased by an average of 17.31% compared with the soil irrigated by fresh water, From these data, we can know that the impact of irrigation water quality on the average daily emissions of CO2 and N2O is not significant (p>0.05). Compared with no fertilizer treatment, the average daily emissions of CO2 flux from the soil fertilized by urea, ammonium sulfate and slow-release fertilizer were respectively increased by an average of 18.67%, 10.20% and 2.76%, and the average daily emissions of N2O flux from the same soil were respectively increased by an average of 117.73%,220.21% and 108.70%. From these data, we can know that fertilizer types had an insignificant impact on the average daily emissions of CO2 flux, but it had an significant impact on the average daily emissions of N2O flux (p>0.05). Compared with the national yield of summer maize production, the yield of summer maize was increased by an average of 19.83% from the fertilized soil, and reduced by an average of 0.83% from the unfertilized soil. From these data, we can realize that the impact of different water qualities and fertilizers on summer maize yield was not significant (p>0.05). Under the premise of saving water and ensuring production, the research result plays a very important role in the study of different water qualities and fertilizers to reduce the emissions of CO2 and N2O.
