摘　　要：对山庄林场背湾子苗圃地土壤进行分层取样,分析土壤含水率、有机质、全氮、速效磷、速效钾和pH值,得出结论:苗圃地土壤含水率在20.23%~21.39%之间,有机质含量在9.82~15.47 g/kg之间,全氮含量在0.66~0.91 g/kg之间,速效磷含量在8.1~10.4 mg/kg之间,速效钾含量在138.4~148.8 mg/kg之间,土壤养分含量等级处于四级至五级之间,土壤肥力水平一般。Soil samples were collected in layers from the Beiwanzi nursery of Shanzhuang Forest Farm,and the soil moisture content,organic matter,total nitrogen,available phosphorus,available potassium,and pH value were analyzed.The conclusions are as follows:the soil moisture content in the nursery ranged from 20.23%to 21.39%,the organic matter content ranged from 9.82 to 15.47 g/kg,the total nitrogen content ranged from 0.66 to 0.91 g/kg,the available phosphorus content ranged from 8.1 to 10.4 mg/kg,and the available potassium content ranged from 138.4 to 148.8 mg/kg.The soil nutrient content level is between grade four and grade five,indicating that the soil fertility level is average.
