- 摘要:
- 为明确玉溪烟区植烟土壤理化性状及其与烟叶品质的关系,采用描述性统计和简单相关分析的方法,研究了该区域土壤主要理化性状并分析了土壤主要理化性状与中部烟叶外观质量、物理特性、化学成分及感官评吸质量的相关性。结果表明,玉溪烟区大部分植烟土壤为弱酸性,较为适宜烟草生长;有机质和速效氮含量丰富,速效磷缺乏,CEC和速效钾含量适中,碳氮比较小,土壤质地以轻壤土和中壤土为主,土壤容重较为适宜。与初烤烟叶外观质量极显著相关的土壤因子是速效钾、有机质和pH。与烟叶物理特性极显著相关的土壤因子是速效钾、CEC、全磷、全钾和碳氮比。与烟叶化学成分极显著相关的土壤因子是有机质、pH、全钾、全磷和速效磷含量。与烟叶感官评吸质量极显著相关的土壤因子是速效氮、速效钾和全钾。其余土壤指标与烟叶品质的相关性较小。速效钾能有效提高烟叶外观质量、物理特性和感官评吸质量,全钾能改善烟叶化学成分和感官评吸质量,速效氮和黏粒含量与烟叶感官评吸质量呈负相关。
- Abstract:
- In order to clarify the physico-chemical properties of the tobacco growing soil and their relationships with tobacco leaf quality in Yuxi Tobacco Growing Area, researches on the soil physico-chemical properties of the area were conducted and their correlations with the middle-part leaf appearance quality, the physical characteristics, the chemical components and the sensory evaluation quality were analyzed by using the methods of descriptive statistics and simple correlation analysis. The results showed that: Most of the tobacco-growing soil in Yuxi Tabocco Growing Area was faintly acid and suitable. The contents of organic matter and available nitrogen were rich, available phosphorus was lacked, CEC and available potassium were moderate, and the carbon and nitrogen were relatively small. The soil texture mainly included light loam and medium loam, and the soil bulk density was relatively appropriate. The soil factors significantly related to the appearance quality of freshly flue-cured tobacco leaves were available potassium, organic matter and pH. The soil factors significantly related to the physical characteristics were available potassium, CEC, total phosphorus, total potassium and the carbon nitrogen ratio. The soil factors significantly related to the chemical components of the tobacco leaves are the contents of organic matter, pH, total potassium, total phosphorus and available phosphorus. The soil factors significantly related to the sensory evaluation quality are available nitrogen, available potassium and total potassium. Other soil indexes had little correlation with tobacco leaf quality. The available K promoted the appearance and physical characteristics of flu-cured tobacco leaves, and improved the sensory evaluation scores of cigerettes. The total K improved the chemical ingredient of flu-cured tobacco leaves and thus benefits the sensory evaluation scores of cigerettes. The available N and soil clay contents showed negetive correlation with the sensory evaluation scores of cigerettes.
