Plant richness affects tree productivity by regulating soil properties and microbial communities. a Stand-level tree volume increment as a function of aboveground plant richness from 2017–2018. b Structural equation models demonstrating the direct and indirect effects of aboveground plant richness on soil nutrient contents, microbial communities and community-level tree productivity, red arrows indicate significant and positive relationships (p < 0.05), and dashed arrows indicate connections with insignificant relationship (p > 0.05). TC: total carbon, TN: total nitrogen, TP: total phosphorus, SM: soil moisture, C/N: the ratio of soil organic C and N, MBC/Corg: the ratio of microbial biomass C and soil organic C
