摘　　要：采用常规2次采收、一次性采收和一次性带茎砍收3种上部叶采收方式,研究其对上部叶烤后烟叶的质量和经济效益的影响。结果显示,与常规采烤相比,上部烟叶一次性采烤和带茎砍烤采收的烤后烟叶经济性状、外观质量均有显著提高,内在化学成分显著优化,但单叶重略有下降。带茎砍烤的整体烘烤时间比常规烘烤延长24 h,用工成本、耗煤成本及耗电成本均高于常规和一次性采烤方式。综合考虑烟叶质量和效益,上部一次性采收和带茎砍收方式是适宜于德昌县推广的上部叶采收方式。The effects of different harvesting methods on the quality and economic benefit of tobacco leaves after curing were studied by using three kinds of upper leaf harvesting methods,including conventional two-times harvesting,one-off harvesting and one-off cutting with stems.The results showed that compared with the conventional harvesting,the economic benefit and appearance quality of the upper tobacco leaves were significantly improved,and the internal chemical composition was significantly optimized,but the single leaf weight decreased slightly.The whole curing time with stem was 24 h longer than that of conventional baking,and the labor cost,coal consumption cost and power consumption cost were higher than those of conventional and one-off curing methods.Considering the quality and benefit of tobacco leaves,the upper one-off harvesting and stem cutting are suitable for the upper leaf harvesting in Dechang County.
