摘　　要：介绍了烤烟三段式烘烤各阶段的操作原则、技术指标及操作方法。变黄阶段 :干球起点温度为 32～ 35℃ ,变黄期间温度 36～ 38℃ ,变黄完成温度 38～ 4 2℃ ,湿球温度比干球温度低 1～ 4℃ ;定色阶段 :干球温度 4 3～ 5 4℃ ,湿球温度 37～ 4 0℃ ;干筋阶段 :干球温度 65～ 68℃ ,湿球温度 4 0～ 4 3℃。并总结出了三段式烘烤技术的关键点 :①低温变黄 ,黄干协调 ;②适速升温定色 ;The operating principles, technique index, and operating methods of three-stage curing were introduced. In yellowing stage: the temperature of dry-bulb was 32-35℃ at the beginning, 36-38℃ in the duration and 38-42℃ at the end, the temperature of wet-bulb was 1-4℃ lower than that of dry-bulb; in fixing color stage: the temperature of dry-bulb was 43-54℃, and that of wet-bulb was 37-40℃; in drying stage: the temperature of dry-bulb was 65-68℃, and that of wet-bulb was 40-43℃. The keypoints were outlined as follows: 1) yellowing tobacco leaves at low temperature, to keep yellowing and drying in harmony; 2) elevating the temperature at a preferable rate to fix leave's color; 3) paying attention to humidity changes in the curing barn.
