Table 2 Multiple linear regression by including additional environmental factors or net primary productivity in addition to temperature based on the microbial β-diversity

Multiple linear regression by including additional environmental factors or net primary productivity in addition to temperature based on the microbial β-diversity.Temp = temperature during the growing season of rice plant; PGS = precipitation during the growing season; OM = organic matter; TN = total nitrogen; NPP = net primary productivity. For soil pH, OM, and TN, their coefficient of variation within each plot were calculated as soil heterogeneity for Pearson correlation analysis. The best fit models with low Akaike’s information criterion (AIC) scores and high r2 values are presented.
