土壤-烟叶中微量营养元素对烤烟吸食品质的影响

对广西中烟主烟区植烟土壤和烟叶中微量营养元素含量进行分析,并对不同产区的烟叶香味成分进行分析,研究这些元素对烟叶香气品质的影响。结果表明,不同产区土壤和烟叶中营养元素含量存在较大差异,且植烟土壤中元素含量对烟叶中营养元素的含量影响较大,从而对烟叶的香味品质产生影响。根据研究提出了具体的施肥建议:依照不同产区土壤营养元素的实际情况,通过施肥调节土壤营养元素含量,协调烟叶中元素含量,从而有效改善烟叶的香气品质。

Effects of Medium and Micro Nutrient Elements in Soil and Tobacco Leaves on Smoking Quality of Flue-cured Tobacco

The medium and micro nutrient elements in the tobacco leaves and soil were analyzed in the main production area of China Tobacco Guangxi Industrial Co.,Ltd.,the flavor components were analyzed,and the effects of these elements on flavor quality were studied.The results showed that there is significant differences of nutrient elements content in soil and tobacco leaf from various producing areas.Specific fertilization suggestions were put forward: according to the actual situation,through fertilizing to adjust soil nutrient elements content,coordinate elements content in tobacco leaf,thus,effectively perfect flavor quality of tobacco.
