| 英文摘要 | Rewetting after precipitation events plays an important role in regulating soil carbon (C) and nitrogen (N) turnover processes in arid and semiarid ecosystems. Here, we conducted a 48-h rewetting simulation experiment with measurements of soil C and N mineralization rates (R-C and R-N, respectively) and microbial biomass N (MBN) at high temporal resolution to explore the pulse responses of R-C and R-N. R-C and R-N responded strongly and rapidly to rewetting over the short term. The maximum RC value (because of pulse effects) ranged from 16.53 to 19.33 mu g C g(soil)(-1) h(-1), observed 10 min after rewetting. The maximum RN varied from 22.86 to 40.87 mu g N g(soil)(-1) h(-1), appearing 5-6 h after rewetting. The responses of soil microbial growth to rewetting were rapid, and the maximum MBN was observed 2-3 h after rewetting. Unexpectedly, there was no correlation between R-C, R-N, and MBN during the process of rewetting, and R-C and R-N were uncoupled. In sum, the pulse responses of R-C, R-N, and microbial growth to simulated rewetting were rapid, strong, and asynchronous, which offers insights into the different responses of microbes to rewetting and mechanisms behind microbes. |
