摘要
对福建烟区1994年48个代表性土壤及相应的烟叶样品的分析化验结果表明：福建烟区土壤养分的平均含量为：有机质25．5g／kg，全氮1．529／kg，速效氮143．50mg／kg，全磷0．35g／kg，速效磷23．03mg／kg，全钾18．61g／kg，缓效钾181．06mg／kg，速效钾64．99mg／kg，交换性镁0．34mg／kg，有效硼0．22mg／kg，含氯量36．67mg／kg。种烟土壤主要为黄泥田和灰泥田。经相关分析，影响福建烟叶质量的主要土壤因素为pH值偏低，有机质和氮素含量偏高，有效钾严重不足，镁、硼等中微量元素普遍较缺乏。生产优质烟叶必需注意选择适宜的土壤类型，调节土壤pH，控制氮肥的使用时期，增加钾肥的施用量并改进施用方法，注意补充镁硼等中微量元素。
48 representative soil and relavant tobacco leaf samples in 1994 have been collected and analysed. The results indicated as follow: in Fujian tobacco growing area, the average content of organic matter、 total-N、available N、 total-P、available P、 total-K、slow-effective K、 available K、exchangable Mg、 effective B、 Cl was 25. 59g/kg, 1. 52g/kg、143. 5g/kg, 0. 35g/kg, 23. 03g/kg、18. 61g/kg、 181、 06mg/kg、 64. 99mg/kg, 0．34mg/kg、0. 22mg/kg,36. 67mg/kg respectively. The main soil types for growing tobacco were yellow-mud field ane marl field. Correlative analysing results showed that the main soil barrier factors affecting Fujiann tobacco leaf quality were low pH、high contont of organ ic matter and N、serious dificiency of available K and widespread dificiency of Mg、B. To produce excellent quality tobacco leaf must pay attention to selecting suitable soil types、regulating soil acidity、controlling applied period of N fertilization,adding K fertiliztation and improving its applied method、supplementing properly the micro-nutrients such as Mg、B etc.
