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)
