K326 (Nicotiana tobacco)was planted in 3 types of soil including purple soil, shanitian soil, and Niugantian soil. Add different percentage of river sand and arenosols to the three types of soil. Tobacco leaves from these tobacco soils textures were selected to investigate the differences in the content of aroma components in flue-cured tobacco. The results showed that the tobacco leaf quality was greatly influenced by soil factors, the purple soil contains the aroma of aldehyde, ketone, phenol 24.23%,the relative content of alcohol aroma was 6.59%, the acid aroma was 12.05%,the ester aroma was 1.96%, the alkane aroma was 39.17%. Purple soil was the best among the 3 types of soil, and niugantian soil was the worst. The content of aroma components in flue-cured tobacco has some changes in the changed soil. The purple soil with 30% river sand which acid aroma added to 18.98%;the shanitian soil with 45% arenosols which aldehyde, ketone, phenol aroma added 24.56%,niugantian soil with 45% river sand which alkane aroma added to 17.55%.In the paper, we investigate the relation between soil and the content of aroma components in flue-cured tobacco. And the soil conditions for high quality flue-cured tobacco planting were also discussed. |
