烤烟烘烤效果受到诸多因素的影响,为在众多的影响因素中识别出烤烟烘烤的关键性影响因素,采用模糊DEMATEL(Fuzzy of Decision Making Trial and Evaluation Laboratory)分析法对影响烤烟烘烤的5大类(烟叶生长环境、烘烤环境、烟叶属性、装烟状况以及烘烤人员素质)17个因素的原因度与中心度进行了分析。结果表明,影响烤烟烘烤的主要因素有光照、大气温度、降雨、干球温度与湿球温度,其中烟草大田生长期间的降雨量、光照与大气温度是影响烤烟烘烤效果的根本因素,对烤房内干球温度与湿球温度的控制是影响烤烟烘烤效果的直接因素,而干球温度对烤烟烘烤的影响最大。
CuItivars K326, Yunyan 87 and Guiyan 4 were used to investigate the curing characteristics and suitabIe harvest maturity of fresh fIue-cured tobacco Ieaves in Ankang tobacco growing areas. ResuIts indicated that the water Ioss of K326 was sIow,and the Ieaves were resistant to curing and reIative easiIy to cure. The water Ioss of Yunyan 87 and Guiyan 4 were quick, and the Ieaves with normal resistance to curing were reIative difficuIt to cure. For Guiyan 4, the shrinkage of CM1 maturity was the Iargest. For K326 and Yunyan 87, the shrinkages of CM2 maturity were the Iargest whiIe the shrinkage of CM1 maturity was the Iowest, but the difference did not reach statistical significance. The proportion of top-middIe-grade tobacco Ieaves and average price for K326 were the highest with XM2, CM2 and BM2 maturity, and for Yunyan 87 were XM1, CM3 and BM2 maturity. For K326, Ieaves with XM2, CM2 and BM2 maturity showed the balanced chemical components and the best smoking quality.
