摘要：

摘要：2005年采集了福建南平烟区有代表性的植烟土壤样品159个，并进行了土壤的理化性状分析。结果表明：福建南平烟区土壤质地以粘壤土、壤土和砂壤土为主；与以往研究相比，土壤pH值有所上升，平均5.59±0.31，仅有38.99%的植烟土壤偏酸性；土壤有机质和速效氮含量仍较丰富，有机质平均34.86±7.88g/kg，碱解氮平均188.3±40.0 mg/kg，49.69%的土壤有机质含量＞35 mg/kg；土壤速效磷含量平均36.5±27.2 mg/kg，有35.85%的植烟土壤速效磷＜20 mg/kg；植烟土壤缓效钾含量平均362.8±241.0 mg/kg ，速效钾含量平均62.3±31.4mg/kg ，速效钾含量＞150mg/kg的植烟土壤仅占1.26%。为此，在烟叶生产上要因地制宜，对偏酸性土壤，要注意施用白云石粉，但应隔1-2年；严格控制氮肥施用量，适当补充磷肥，并注意增施钾肥。

Abstract:

Abstract : The nutrients in 159 soil samples collected from tobacco-growing areas in Nanping of Fujian provinces were analyzed．The results showed that most soils texture was caly loam or loam or sandy loam, the average soils pH value was 5.59±0.31, 38.99% of the average soils pH value is less than 5.5；the high soil organic matters and available nitrogen were found，the average contents of soils organic matters was34.86±7.88 g/kg， alkalihydrolyzable N was188.3±40.0 mg/kg，49.69%of the average contents of soils organic matters was over 35 g/kg； the average contents of soil available P was36.5±27.2 mg/kg，35.85% of the average contents of soil available P was lower than 20 mg/kg；the results showed that soil available K was so low，the average buffer available　K、available K was362.8±241.0 mg/kg ，62.3±31.4mg/kg，respectively,　only 1.26% of soil available K was over 150mg/kg.The fertilization suggestion of controlling N， increasingPand K were recommended. For acid soil , application of lime was recommended.
