摘　　要：对三门峡市卢氏、灵宝、陕县和渑池四个主要烤烟产区的700个烟田土壤样品进行了化验分析。结果表明:全市烤烟主产区烟田土壤的酸碱度及有机质、全氮、碱解氮、速效磷和速效钾含量等指标总体上均处于适宜或较高水平,有利于优质烟叶生产;对4个主产区烟田土壤的营养指标进行了详细分析,并据此提出了相应的平衡施肥建议。This study analyzed 700 soil samples from flue -cured tobacco fields in four main flue -cured tobacco production areas in Sanmenxia city. The results indicated that the pH- value, organic matter, total nitrogen, alkaline - hydrolyzed nitrogen, available phosphorus and available potassium content in the soil were generally at suitable or higher level, which was advantageous for the pro- duction of high - quality tobacco. In addition, the soil nutrient indexes of 4 main tobacco - planting areas were analyzed in detail, and the corresponding balanced fertilization suggestions were proposed.
