Moreover, soil P and litter C:P, soil C and leaf C, and soil C:P and leaf P were highly significantly negatively correlated ( P < 0.01).
Moreover, soil P and litter C:P, soil C and leaf C, and soil C:P and leaf P were highly significantly negatively correlated ( P < 0.01).
The litter C:N ratio showed a trend of decreasing and then increasing with increasing sampling time at 6 and 10 years of recovery, and the value in October was markedly ( P< 0.05) greater than that in May ( Figure 5B ).
The leaf, litter, and soil N:P ratios were 35.76-47.39, 34.73-51.29 and 4.01-8.00, respectively, at different restoration years, with an overall trend of litter > leaf > soil ( Figure 5 ).
