摘要
【目的】改善高山烟区白肋烟晾制易发生棚烂和霉变现象,提高白肋烟的晾制质量。【方法】对简易拱形晾晒棚、简易拱形增温晾晒棚、"89式"增温晾房、"89式"标准晾房(CK)4种晾制模式进行晾制对照试验。【结果】简易拱形晾晒棚和简易拱形增温晾晒棚对晾房内的平均温湿度控制效果优于"89式"增温晾房和"89式"标准晾房;简易拱形增温晾晒棚产生的经济效益最高,产量较对照提高12.35 %、产值增加8433.90元/hm^2、上中等烟率较对照提高7.82 %、烟叶霉变率降低至4.09 %,简易拱形晾晒棚产生的经济效益次之,且能将烟叶霉变率控制在4.17 %。【结论】综合比较4种晾制模式产生的经济效益和成本投入,简易拱形晾晒棚和简易拱形增温晾晒棚模式更符合高山烟区白肋烟持续性发展和晾制要求。
【Objective】The study was conducted to improve the phenomena of barn rot and mildew during air-curing process in alpine tobacco area and raise the air-curing quality of burley tobacco.【Method】A control experiment was conducted among four air-curing modes:simple arched air-curing shed,simple arched heating air-curing shed,"89"heating drying room and"89"standard drying room(CK).【Result】The effects of simple arched air-curing shed and simple arched heating air-curing shed on the average temperature and relative humidity control during air-curing process were better than those of"89"heating drying room and"89"standard drying room.The simple arched heating air-curing shed mode had the highest economic benefits,with yield improved by 12.35%,output value increased 8433.90 yuan/hm^2,rate of high and middle quality tobacco raised by 7.82% and proportion of tobacco mildew reduced to 4.09%.The simple arched air-curing shed mode had lower economic benefits than those of simple arched heating air-curing shed mode,the tobacco mildew rate could be controlled at 4.17% by such mode.【Conclusion】Considering the economic benefits and cost inputs of the four air-curing modes,simple arched air-curing shed and simple arched heating air-curing shed were more suitable for the air-curing requirements and sustainable development of burley tobacco in alpine tobacco areas.
