Fig. 1 Dynamic variation of NH3+-N (a) and NO3–N (b) contents in lawn soils with or without urea in a 15-day incubation. Different letters denote significant differences between treatments (P < 0.05). Vertical bars denote standard errors of the mean (n = 3)
Fig. 2 Temporal variation of N2O flux (a) and cumulative N2O emissions (b) from lawn soils with or without urea over a 15-day incubation. Different letters denote significant differences between treatments (P < 0.05). Vertical bars denote the standard error of the mean (n = 3)
Fig. 3. Contributions of fungi and bacteria on N2O emissions in the lawn soil. Different letters denote significant differences between treatments (P < 0.05). Vertical bars denote the standard error of the mean (n = 3)
Fig. 4 Relative abundances of the main fungal phyla (a) and genus (b) in the lawn soil of all treatments. Vertical bars denote the standard error of the mean (n = 3)
Fig. 5 Principal coordinate analysis (PCA) of fungal community structure in all treatments. The first two principal coordinate axes together explained 85.44% of the fungal variation
Fig. 6 Correlations between N2O emission, soil properties and the community structure of fungal phyla (a) and genus (b) as determined by redundancy analysis (RDA)
Fig. 7 Regression analysis of N2O emissions with fungal genus in different nitrogen treatments (n=12)
