摘　　要：2004年在河南烟区采集449个植烟土壤样品进行化验分析。结果表明,河南省植烟土壤有机质含量平均在13.0gkg-1,总体上处于适宜水平;烟区间土壤pH值变化范围不大,多数样品pH为中性或偏碱性;有效氮含量处于适宜水平;速效磷含量除豫中和豫南烟区的个别地方较高之外,其它烟区含量均偏低;速效钾含量平均为142.6mgkg-1,烟区之间变异较大;土壤水溶性氯含量整体偏高,烟区之间变异较小;土壤阳离子交换量处于中等水平,仅豫中和豫东个别地区稍差。449 soil samples were collected and analyzed in tobacco-growing areas in Henan Province. Results indicated that the average content of organic matter was 13.0 g kg, which was in appropriate level. Soil pH among different tobacco-growing areas fluctuated moderately, which belonged to neutrality and deflected to alkalescence slightly. Available N was in a suitable level. The content of available P was low in the tobacco-growing areas except some places of the middle and the southern Henan. The average content of available K is 142.6 mg kg and the content variation among different areas was great. The content of soluble Cl^- was high in all the tobacco-growing areas and the variation of soluble Cl content was slight. CEC was in a middle level and the content was lower only in some areas of eastern and middle Henan.
