Among them, the root decomposition constant of low-order roots showed an increasing trend with increase in Ca: Al ( R 2 = 0.112, P = 0.289) and Mg: Al ratios ( R 2 = 0.219, P = 0.125) (Fig.

In addition, across the five sampling periods, root chemistry and soil environment showed a trend of synergistic inhibition in the decomposition of lower-order roots, whereas they exhibited a trend of mutually weakening inhibitory effects in higher-order roots.
