| 摘 要： | 采集延安市典型园林绿地土壤,分析土壤的pH值、容重、孔隙度及土壤有机质、N、P、K有效养分含量,以摸清园林绿地土壤的基本性状及肥力状况。结果表明:园林绿地土壤与自然土壤pH比较接近;土壤容重偏大、总孔隙度偏小;土壤有机质、碱解氮和速效磷含量均偏低,速效钾在新建园林绿地含量高,旧建园林绿地含量中等;延安市园林绿地土壤肥力低下(钾除外);应做好园林绿地土壤的培肥工作,为园林植物正常生长提供良好的土壤环境。

| Abstract: | In order to analyze the basic property and fertility of greenbelt soil,we collected some representative samples of greenbelt soil in Yan'an and study the pH,unit weight,porosity as well as the content of available nutrient such as nitrogen,phosphorus and potassium.The results showed that the pH of greenbelt soil was relatively close to that of natural soil;the unit weight of greenbelt was relatively higher and total porosity was lower than natural soil;the soil organic matter,alkali-hydro nitrogen and rapid... |
