Centered Log-Ratio (CLR) transformation converted value of functional groups of wood-inhabiting bacteria (a) chemoheterotrophy (b) ureolysis (c) methylotrophy (d) intracellular parasites in different treatments, Lowercase letters were used to indicate the significant difference (P < 0.05) among the five treatments within the same year after wood decomposition. The number before and after "/" represents the pyrolysis temperature of biochar (°C) and applying amount of biochar (kg m−2), respectively
