摘要
长期火烧山后土壤恶化,利用种植米老排(Mytilarialaosensish)改善林地.分析米老排林地土壤的理化性质,结果表明:米老排林地土壤腐殖质层变厚(2～6cm)、变松.土壤养分尤其是全氮和速效N、P、K含量得到提高.说明米老排在恶化林地作为先锋树种对改善土壤理化性质具有快速有效的作用.
Soil physical & chemical properties worsened for long burning off,while the planting Myti Laria Laosensish may improve them Physical & chemical properties of woodland were Analysed in this paper.The results showed that the soil humus layer got thicker (2～6cm increased) and looser,and the soil nutrient (in especial,organic matter,total nitrogen and available nitrogen,phosphorus and potassium etc.) got increased.That means being as the first plant planted in worsened land,Myti Laria Laosensish may be improved the soil physical and chemical properties fast and better.
