摘　　要： 为探讨成土母岩与烟叶品质的关系,对16种母岩发育的1 087个土壤样品和对应的1 440个烟叶样品进行了比较分析。结果表明:不同母岩发育成的土壤理化性质差异很大,种植的烟叶品质也有较大差异。砂岩以及含砂母岩发育的土壤有机质和氮含量较低,保肥性能较差;玄武岩发育的土壤速效钾含量高;凝灰岩发育的土壤氯离子含量低;板岩发育的土壤交换性钙、镁含量低;钙质紫色和玄武岩的阳离子交换量高。在玄武岩、凝灰岩、钙质紫色岩上种植的烟叶具有高糖、低碱的特征;在板岩上种植的烟叶具有高钾、高糖碱比的特征。在白云质灰岩种植的烟叶具有高碱、低糖的特征。从感官质量看,板岩种植的烟叶得分最高,凝灰岩、钙质紫色岩、页岩、玄武岩其次;砂岩以及含砂母岩上种植的烟叶得分最低。 1087 soil samples from 16 kinds of mother rocks and 1440 tobacco samples were analyzed to study the relationship between tobacco quality and mother rocks.The results showed that there was obvious difference in soil physical and chemical properties between different mother rocks and in quality of tobacco leaves.The organic matter and nitrogen content,and fertilizer conservation capacity of the soil developed from sand rock and sandy rock is lower.The available K content in the soil developed from basalt is higher.The chlorine content in the soil developed from tuff is lower.The exchangeable calcium and magnesium content in the soil developed from slate is poor.The CEC content in the soil developed from purple rock with calcium and basalt is high.The leaves of tobacco plants planted in the soils developed from basalt,tuff and purple rock with calcium has the characteristics of high sugar and lower nicotine content.The leaves of tobacco plants planted in the soil developed from slate has the characteristics of high K content and higher sugar/nicotine ratio.The leaves of tobacco plants planted in the soil developed from dolomitic limestone has the characteristics of high nicotine and lower sugar content.The sensory quality score of tobacco plants planted in the soil developed from slate is the highest,followed by the soils developed from tuff,purple rock with calcium,shale,basalt,sand rock and sandy rock.
