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 planting land in Zhaoqing of Daqing as the research object, four attributes of organic matter, alkali-hydrolyzable nitrogen, available phosphorus and available potassium were selected as evaluation indexes. The modified Nemoro formula was used to evaluate the soil fertility quantitatively. The results showed that the average soil fertility coefficient Pi of tobacco planting was 2.398-2.608, the minimum of Pi was 1.420-1.840 and the comprehensive fertility coefficient P was 1.48-1.72. The order of P of the total fertility coefficient of tobacco topsoil in each year was P2003> P2008> P2004> P2004> P2002> P1994.2002 ~ 2008 The fertility of tobacco planting soil in Zhaozhou belongs to the fertile level. In 1994, the soil fertility of tobacco planting in Zhaozhou was normal.
