摘 要 ：对30年生栽杉留阔模式及对照的杉木纯林生产力和土壤肥力进行了研究,结果表明:栽杉留阔模式中杉木个体比对照的大,模式总蓄积量比对照的增加11.35%,土壤结构和水分性能得到改善,土壤腐殖质品质变好,土壤养分贮量和供应强度增强,土壤微生物数量增加,土壤生化活性增强,土壤肥力得到明显改善。

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.
