| Abstract: | The soil humus and fertility of the management patttern of planting broad-leaved tree with reserving Chinese fir (PBWRC) and the Chinese fir stand regenerated from sprouts (CPRS) were studied. The results indicated that the soil organic matter and total N of 33-year-old PBWRC stand increased, the soil biochemistry activity strengthened and the amount of available nutrient supply enhanced. The HA/FA, E 4 increased, E 4 /E 6 descended, loosely and tightly combined humus contents and its ratio ascended and the activation of soil humus enhanced. All above show that the soil fertility has heen improved obviously which promotes tree growth of PBWRC stand. |
