| Abstract: | The soil humus and fertility of the management pattern of planting broadleaf and Chinese fir alternatively(PBCA) and the Chinese fir stand regenerated from sprouts(CPRS) were studied. The results indicated that the soil organic matter and total N of 26-year-old PBCA stand increased. the activities of soil biochemistry strengthened. the amount of available nutrient supply enhanced. Soil humus. the ratio of HA/FA humic acid and E4 value increased. E4/E6 descended. loosely and tightly combined humus contents and its ratio ascended. the activation of soil humus enhanced. The soil fertility was improved obviously in PBCA stand. |
