山东沂水植烟土壤类型与烟叶品质关系的调查研究

对山东省沂水县的２４个植烟乡（镇）４种不同母质发育的土壤的产是化与所产烟叶的常规化学成分及评吸结果的关系进行了研究。研究表明，不同母质发育的土壤的理化性质存在较大的差异。主要表现在ＰＨ、有机质、速效钾的含量差异。不同母质发育的土壤所产的烟叶的评吸质量也存在着差异。土壤有机质含量高，所产烟叶的香气质好、香气量足、杂气轻，土壤速效钾含量高，烟叶香气质好，要想进一步提高烟叶的质量，必须提高高土壤有机质的

Investigation onrelationship between soil types and tobacco leaf quality in Shandong

Soils developed from 4 different mother rocks were collected from 24 tobacco planting towns in Yishui County,Shandong Province.Relationships between physical,chemical properties of the soil and chemical components,smoking quality of tobacco leaf were analyzed.The results showed that differences in physical and chemical properties were mainly observed among the soils pH,content of organic matters and rapid available potassium.Differences in smoke quality of tobacco leaf produced on the soils were also observed.The results also demonstrated that less offensive taste quality tobacco with high content of aroma could be produced on soils with high content of organic matters and potassium.The potential methods to increase potassium content of tobacco leaf were also discussed.
