英文摘要Atmospheric deposition nitrogen (ADN) increases the N content in soil and subsequently impacts microbial activity of soil. However, the effects of ADN on paddy soil microbial activity have not been well characterized. In this study, we studied how red paddy soil microbial activity responses to different contents of ADN through a 10-months ADN simulation on well managed pot experiments. Results showed that all tested contents of ADN fluxes (27, 55, and 82 kg N ha(-1) when its ratio of NH4+/NO3--N (R-N) was 2:1) enhanced the soil enzyme activity and microbial biomass carbon and nitrogen and 27 kg N ha(-1) ADN had maximum effects while comparing with the fertilizer treatment. Generally, increasing of both ADN flux and R-N (1:2, 1:1 and 2:1 with the ADN flux of 55 kg N ha(-1)) had similar reduced effects on microbial activity. Furthermore, both ADN flux and R-N significantly reduced soil bacterial alpha diversity (p < 0.05) and altered bacterial community structure (e.g., the relative abundances of genera Dyella and Rhodoblastus affiliated to Proteobacteria increased). Redundancy analysis demonstrated that ADN flux and R(N)the soil bacterial community. The finding highlights how paddy soilmicrobial community response to ADN and provides information for N management in paddy soil. (C) 2018 Elsevier B.V. All rights reserved.
