The irrigation method in the field has a certain influence on the utilization efficiency of nitrogen fertilizer and nitrogen metabolism. In this paper, the effects of nitrogen fertilizer application under different irrigation methods on nitrogen metabolism and yield quality of Japonica rice were studied. The results showed that under drip irrigation, the yield of Japonica rice was the highest and the nitrogen utilization efficiency was the highest when the nitrogen fertilizer application rate was 150 kg/hm². At the same time, under drip irrigation, the starch content in the rice grain was the highest and the protein content was relatively low when the nitrogen fertilizer application rate was 150 kg/hm².
