Abstract:
The stand productivity, soil fertility under the management pattern of planting 30-year-old Chinese fir with keeping broad-leaved trees (PCKB) and pure Chinese fir stand (control) were studied. The results indicated that the tree size of Chinese fir in PCKB was bigger than that of the control. The stand total volume of PCKB was 11.35% higher than that of the control. Compared with the control, the soil structure and moisture condition were improved, the activities of soil biochemistry and the activation of soil humus strengthened, the amount of available nutrient supply and the amount of soil microorganism increased. The soil fertility was improved obviously and it promote tree growth of PCKB stand.
Key words: Pattern of planting Chinese fir with keeping broad-leaved trees(PCKB), Stand productivity, Soil fertility
