摘要
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。
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 to bacco-planted soil fertility coefficient Pimax was between 2. 398--2. 608,Pimax was 1. 420--1. 840,comprehensive fertility coefficient P was 1.48-1.72,the integrated coefficient P of the tobacc^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.
