| 摘 要： | 对大岗山天然常绿阔叶次生林中25个样地0～20cm和20～40cm土层土壤养分进行了测定分析。结果显示:(1)大岗山常绿阔叶林土壤养分含量丰富,但钾素养分比较贫乏;(2)不同林分土壤有机质、全氮、全钾、有效磷含量差异不大,但对全磷及有效钾含量差异显著,均为针阔混交林>常绿阔叶林>常绿落叶阔叶混交林>毛竹林;(3)就同一林分类型而言,土壤有机质、全氮、速效磷及有效钾含量随着土壤深度的增加显著递减;全磷含量随着土壤深度的增加呈递减的趋势,但减小不明显;全钾含量在不同土层间变化规律不明显,半落叶阔叶林、针阔混交林全钾含量随土层深度的增加而增加,毛竹林土壤全钾含量随土层深度的增加明显降低。 |

| Abstract: | The soil nutrients of 0-20 cm and 20-40 cm soil layers of 25 plots in Dagangshan natural evergreen broad-leaved forest were measured and analysed.The result shows that:(1) Dagangshan evergreen broad-leaved forest soil is rich in nutrients,but relatively poor in potassium nutrition.(2)In different forest types there are no signficant differences in the soil organic matter,total nitrogen,total potassium,rapidly available phosphorus content,but there are significant differences in the total phosphorus and avai... |
