The field trail was conducted in Wulong county of Chongqing city in 2010, and Virginia K326 was the tested cultivar. The middle leaves were harvested and plaited after maturity, and then cured with the three-stage six-step curing technology and traditional three-stage curing technology, respectively. Three replicates were established for each of the two curing technologies. Then, chemical constituents, aromatic substances and smoking quality were analyzed. The results show that compared with the traditional three-stage curing technology, the three-stage six-step curing technology produces more suitable ratios of chemical constituents, higher aromatic component content and higher smoking quality grade of tobacco leaves. Therefore, the continuous improvement of corollary equipment and matching technologies is expected to widen the applications of the three-stage six-step curing technology in tobacco and provide a strong technical support for the development of the tobacco industry.展开更多
