Abstract: This trial was carried out to seek after curing technique of lower leaves of flue-cured tobacco ‘KRK26’, and to improve curing quality. The effects of curing techniques on the content of aroma substance and smoking quality were studied. The three curing techniques were made by different temperature and humility conditions. The results indicated that the curing technique of middle temperature and middle humidity had the highest aroma materials content and score of the smoking indexes in the three curing techniques being 534.265 μg/g and 65.9 cent followed by the curing technique of lower temperature and lower humidity, was 532.621 μg/g and 64.7 cent, the lowest curing technique of middle temperature and higher humidity was 456.301 μg/g and 64 cent. The smoking quality score had the same trend line of change with the content of aroma. Utilization of curing technique of middle temperature and middle humidity can make an effective improvement of the quality.
