MATK and infection: DSE infection intensity increased the accumulation of plant total P by directly increasing plant CTK content and soil glomalin, which indirectly increased plant biomass in separate inoculation treatments (χ2 = 18.329, df = 15, P = 0.246, RMSEA = 0.098, GFI = 0.87, AIC = 78.329; Fig. 5A).
