以大庆肇州植烟土地为研究对象,选用有机质、碱解氮、速效磷、速效钾4项属性作为评价指标,运用修正的内梅罗(Nemoro )公式,对土壤肥力进行定量综合评价.结果表明,植烟土壤肥力系数Pi平均为2.398～2.608,Pi最小为1.420～1.840,综合肥力系数P为1.48～1.72,各年度肇州植烟表土综合肥力系数P大小顺序为:P2003>P2008>P2006>P2005>P2004>P2002>P1994.2002～2008肇州植烟土壤的肥力属肥沃水平,1994年肇州植烟土壤肥力一般.
以大慶肇州植煙土地為研究對象,選用有機質、堿解氮、速效燐、速效鉀4項屬性作為評價指標,運用脩正的內梅囉(Nemoro )公式,對土壤肥力進行定量綜閤評價.結果錶明,植煙土壤肥力繫數Pi平均為2.398～2.608,Pi最小為1.420～1.840,綜閤肥力繫數P為1.48～1.72,各年度肇州植煙錶土綜閤肥力繫數P大小順序為:P2003>P2008>P2006>P2005>P2004>P2002>P1994.2002～2008肇州植煙土壤的肥力屬肥沃水平,1994年肇州植煙土壤肥力一般.

Taking the tobacco-planted soil of Zhaozhou county as the object of study,we selected the organic matter,available N,P and K to take the evaluating indicators,and used the Nemoro formula to evaluate the soil fertility.The results indicated:the tobacco-planted soil fertility coefficient Pimean was between 2.398～2.608,Pimin was 1.420～1.840,comprehensive fertility coefficient P was 1.48～1.72,the integrated coefficient P of the tobacco-planted soil in Zhaozhou in various years was:P2003>P2008>P2006>P2005>P2004>P2002>P1994.The tobacco-planted soil fertility was the fertile level in 2002～2008,and was low in 1994.
