| 英文摘要 | Experiments were conducted to examine the effects of long-term fertilization and acute Zn toxicity on the size, nitrification activity and community structure of autotrophic ammonia-oxidizing populations of the beta-subgroup of the class Proteobacteria in arable soils. Plots under different long-term fertilization regimes were sampled, and then different concentrations of ZnCl2 were spiked into soil samples for 8 weeks. It was found that long-term fertilization significantly increased nitrification rates and population size, and there was a positive correlation between them. A shift in the composition of AOB was also detected in samples fertilized with mineral N fertilizer (NPK) and organic matter (OM) as compared to unfertilized sample. EC50 values suggested that there was no significant difference in Zn toxicity to nitrification rates among the three fertilization treatments. Long-term fertilization did not improve the resilience of AOB activity to Zn toxicity. |
