图6 非根际土壤细菌(a)、真菌(b)优势菌门与土壤碳氮因子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, ** P < 0.01。TC: 全碳; TN: 全氮; SOC: 土壤有机碳。

Fig. 6 Pearson correlation analysis of dominant bacterial (a) and fungal (b) phyla in non-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, ** P < 0.01. TC, Total carbon; TN, Total nitrogen; SOC, Soil organic carbon.
