| 摘 要： | 2003年采集衡南县主产烟区的118个植烟土壤样品分析表明,衡南县植烟土壤的pH值平均为5.29,大部分土壤明显偏酸性；土壤有机质含量丰富,有接近一半的土壤其含量超过了35g/kg,几乎所有土壤的碱解氮含量在120mg/kg以上,部分植烟土壤有效磷、有效锌和交换性钙缺乏,且不同类型的土壤差异较大；而大部分土壤有效钾、交换性镁、有效硼和有效氯含量较低.

| Abstract: | The analysis of 118 soil samples collected in 2003 from main tobacco-growing areas of Hengnan showed that the average pH value was 5.29,and most of soil was obviously acidic.The content of organic matter was rich,nearly half of soil samples containing more than 35 g/kg.Available nitrogen content in almost all of soil samples was above 120 mg/kg,and parts of soil samples was lack of available phosphorus,available zinc and exchangeable calcium,while the difference among different types of soil was clear.In most of soil samples,content of available potassium,exchangeable magnesium,available boron and chlorine was lower. |
