摘要： 为了解山东省石榴主产区（枣庄市峄城区）土壤肥力状况，采用室内分析测定的方法，对枣庄市峄城区万亩石榴园15个果园的土壤有效养分进行测定分析。结果表明，石榴园土壤pH范围在6.78~7.42之间，其平均值为7.17，适合石榴生长；有机质含量总体处于较低水平，变化范围为7.88~13.89 g/kg，平均值仅为10.93 g/kg；土壤碱解氮变化范围为15.80~77.20 mg/kg；有效磷含量变化范围为5.48~140.33 mg/kg，平均值为36.75 mg/kg；土壤有效钾变异变化范围为57.0~262.0 mg/kg，平均值为169.0 mg/kg。土壤碱解氮含量处于较低水平，土壤有效磷缺乏过量并存，有效钾含量处于适宜和丰富水平。为此，认为试验区石榴园要增施有机肥，加强氮供应，根据园地情况调控使用磷肥、钾肥。

Abstract: Knowing soil nutrient fertility status is a basis to formulate a suitable fertilizationg strategy. Samples collected from 15 pomegranate orchards in Zaozhuang were tested and classified in present study. Based on the soil analysis. Results indicated that, soil pH was between 6.78 and 7.42 and average content was 7.17. The content of soil organic matter was between 7.88 g/kg and 13.89 g/kg and average contents was 10.93 g/kg. The content of soil available N was between 15.80 mg/kg and 77.20 mg/kg and average contents was 41.62 mg/kg. The content of soil available P was between 5.48 mg/kg and 140.33 mg/kg and average contents was 36.75 mg/kg. The content of soil available K was between 57.0 mg/kg and 262.0 mg/kg and average contents was 169.0 mg/kg. The content of soil organic matter and soil available N was generally lower. The content of soil available K was medium or abundance. The fertilization suggestion was controlled by P, K, when the content of N and organic fertilizer was lower.
