英文摘要	Ammonia oxidizing archaea (AOA) and bacteria (AOB) mediate a crucial step in nitrogen (N) metabolism. The effect of N fertilizer rates on AOA and AOB communities is less studied in the wheat-fallow system from semi-arid areas. Based on a 17-year wheat field experiment, we explored the effect of five N fertilizer rates (0, 52.5, 105, 157.5, and 210 kg ha(-1) yr(-1)) on the AOA and AOB community composition. This study showed that the grain yield of wheat reached the maximum at 105 kg N ha(-1) (49% higher than control), and no further significant increase was observed at higher N rates. With the increase of N, AOA abundance decreased in a regular trend from 4.88 x 10(7) to 1.05 x 10(7) copies g(-1) dry soil, while AOB abundance increased from 3.63 x 10(7) up to a maximum of 8.24 x 10(7) copies g(-1) dry soil with the N105 treatment (105 kg N ha(-1) yr(-1)). Application rates of N fertilizer had a more significant impact on the AOB diversity than on AOA diversity, and the highest AOB diversity was found under the N105 treatment in this weak alkaline soil. The predominant phyla of AOA and AOB were Thaumarchaeota and Proteobacteria, respectively, and higher N treatment (N210) resulted in a significant decrease in the relative abundance of genus Nitrosospira. In addition, AOA and AOB communities were significantly associated with grain yield of wheat, soil potential nitrification activity (PNA), and some soil physicochemical parameters such as pH, NH4-N, and NO3-N. Among them, soil moisture was the most influential edaphic factor for structuring the AOA community and NH4-N for the AOB community. Overall, 105 kg N ha(-1) yr(-1) was optimum for the AOB community and wheat yield in the semi-arid area.
