【Objcetive】 Tobacco-rice rotation can effectively improve soil ecology, promote agricultural efficiency and increase farmers' income. Nitrogen fertilizer is a key factor affecting the growth and development of rice. In order to determine the optimal nitrogen application rate and to give full play to the high quality and high yield potential of the superior quality rice “Fuxiangzhan” in the tobacco-rice rotation areas of Fujian Province, 【Method】 Five nitrogen rates, (CK: 0, N1: 51.75, N2: 103.5, N3: 155.25, and N4: 207 kg/ hm2 by nitrogen) were set to analyze effects on photosynthetic characteristics, grain yield and its components, grain quality and aroma of brown rice under the field environment. 【Result】 The results showed with the increase of nitrogen application rate, the growth duration of “Fuxiangzhan” was gradually prolonged, chlorophyll SPAD value, net photosynthetic rate, chloroplast size, sucrose and starch contents in flag leaves were increased, and all the parameters mentioned above reached the highest value in N3 or N4 treatment. The grain number per panicle and grain yield maximized in N2 treatment, but the seed setting rate and 1000-grain weight decreased with the increase of nitrogen application rate. For the processing quality of grain, it performed best in N2 treatment. The appearance quality and eating quality were not significantly affected by nitrogen rates. The total protein contents increased with the increase of nitrogen rates. For RVA profile, the peak viscosity, hot viscosity, final paste viscosity and breakdown value decreased, while the setback viscosity value increased. The content of 2-acetyl-1-pyrroline (2-AP) in brown rice under N2 treatment was the highest. 【Conclusion】 The results showed nitrogen treatment promoted the photosynthesis of “Fuxiangzan”, but excessive nitrogen made plants late-ripening, reduced seed setting rate and yielding. At the nitrogen application rate of N2 (103.5 kg / hm2), we struck a balance between high yield and good quality with the most aroma substances accumulated. This study laid a foundation for the further popularization and application of “Fuxiangzhan” in production and the development of high-quality rice industry in the tobacco-rice rotation areas of Fujian Province.
