图5 根际土壤细菌(a)、真菌(b)优势菌门与土壤碳氮因子的Pearson相关性分析。颜色条刻度表示Pearson相关系数(r)值。橙色代表正相关, 绿色代表负相关; 颜色深浅表示相关性强弱; * P < 0.05。TC: 全碳; TN: 全氮; SOC: 土壤有机碳。

Fig. 5 Pearson correlation analysis of dominant bacterial (a) and fungal (b) phyla in rhizosphere soil as related to soil carbon and nitrogen factors. The color bar scale represents the Pearson correlation coefficient (r) value. Orange represents a positive correlation, and green represents a negative correlation; The shade of color indicates the strength of the correlation; * P < 0.05. TC, Total carbon; TN, Total nitrogen; SOC, Soil organic carbon.
