Both CO 2 GWP and N 2 O GWP exhibited an increasing trend with higher nitrogen application rates, with the N3 treatment showing average increases of 47.35% and 163%, respectively, compared with the N0 treatment.
Over the two growing seasons, the average CH 4 emission flux ranged from −0.24 to 0.02 mg·m −2 ·h −1 , and showed a decreasing trend with an increasing nitrogen application rate and aggravated water deficit.
