稀土元素肥料对烤烟致香物质含量和评吸质量的影响

Effects of Rare Earth Fertilizer on Contents of Aroma Components and Smoking Quality of Flue-cured Tobacco

为了探索提高烟叶香气质量的农艺措施,采用大田试验,研究了稀土元素肥料对烤烟致香物质含量和评吸质量的影响。结果表明,稀土元素肥料能明显提高烟叶中总致香物质含量和主要致香物质含量,以稀土元素肥料"利烟王"和"益植素"(固)的效果较为明显。稀土元素肥料还可改善烟叶评吸质量,各部位烟叶的评吸得分以"利烟王"处理高于其他处理,其香气质好、香气量足、余味舒适、刺激性较小,评吸质量好。

In order to find out the agricultural measures for improving the flavor quality of tobacco leaves, the effects of rare earth fertilizer on contents of aroma components and smoking quality of flue-cured tobacco leaves were studied with field experiments. The results showed that the contents of total aroma components and major aroma components increased with application of rare earth fertilizer, particularly ＂Liyanwang＂ and ＂Yizhisu＂ （solid）. The smoking quality of tobacco leaves was also improved by rare earth fertilizer, the tobacco applied with ＂Liyanwang＂ offered good flavor quality, rich flavor quantity, comfortable aftertaste and less irritation,and was scored higher in panel test.
