英文摘要	Nitrous oxide (N2O) contributes up to 8% of global greenhouse gas emissions, with approximately 70% from terrestrial sources; over one-third of this terrestrial emission has been linked to increased agricultural fertilizer use. Much of the nitrogen in fertilizers is converted to N2O by microbial processes in soil. However, the potential mechanism of biofertilizers and the role of microbial communities in mitigating soil N2O emissions are not fully understood. Here, we used a greenhouse-based pot experiment with tea plantation soil to investigate the effect of Trichoderma viride biofertilizer on N2O emission. The addition of biofertilizer reduced N2O emissions from fertilized soil by 67.6%. Quantitative PCR (qPCR) analysis of key functional genes involved in N2O generation and reduction (amoA, nirK, nirS, and nosZ) showed an increased abundance of nirS and nosZ genes linked to the pronounced reduction in N2O emissions. High-throughput sequencing of nosZ showed enhanced relative abundance of nosZ-harboring denitrifiers in the T. viride biofertilizer treatments, thus linking greater N2O reduction capacity to the reduced emissions. Our findings showed that biofertilizers can affect the microbial nitrogen transformation process and reduce N2O emissions from agroecosystems.
