摘要
采用5种晾房(黑膜晾房、红瓦晾房、美式晾房、涂泥晾房、钢架晾房)于四川省达州市研究了白肋烟晾制期间的温湿度差异及对晾制后烟叶品质的影响。结果表明,不同晾房对温度和相对湿度的调节能力有显著差异。晾房内平均温度表现为美式晾房>钢架晾房>红瓦晾房>黑膜晾房>涂泥晾房,平均昼夜温差表现为钢架晾房>黑膜晾房>涂泥晾房>美式晾房>红瓦晾房,各晾房的温度控制能力表现为涂泥晾房<黑膜晾房<钢架晾房<美式晾房<红瓦晾房,从温度方面分析,钢架晾房和红瓦晾房较好,黑膜晾房和涂泥晾房较差。晾房内平均相对湿度排序为黑膜晾房>涂泥晾房>美式晾房>红瓦晾房>钢架晾房,与室外湿差表现为黑膜晾房>涂泥晾房>美式晾房>钢架晾房>红瓦晾房,从相对湿度方面分析,钢架晾房和红瓦晾房的排湿效果佳,黑膜晾房和涂泥晾房的效果较差。不同晾房晾制对晾制后烟叶外观影响不大,各晾房晾制的烟叶外观品质符合优质白肋烟的要求。不同晾房晾制对烟叶的化学成分有不同程度的影响,除涂泥晾房糖含量偏高外,各晾房处理的烟叶化学成分含量基本符合优质白肋烟的品质要求。从不同晾房的建造成本、实用性、保温排湿效果和对化学成分的影响综合分析,钢架晾房最适合当地调制优质白肋烟的要求。
Five air-curing barns （black plastic-film barn, red tile barn, American barn, mud barn and steel frame barn） were established in Dazhou City, Sichuan Province. Differences in temperature and relative humidity during burley tobacco air-curing among the different barns were then investigated. Tobacco leaf quality after air-curing in different barns was also determined. The results showed significant differences in adjustment of temperature and relative humidity among the different barns. Average temperature in different barns was in the order of： American barn 〉 steel frame bam〉 red tile barn 〉 black plastic-film barn 〉 mud barn. Average diurnal amplitude in temperature was in the order of： steel frame barn 〉 black plastic-film barn 〉 mud barn 〉 American barn 〉 red tile barn. Adjustment ability of temperature was in the order of： mud barn 〈 black plastic-film barn 〈 steel frame barn 〈 American barn 〈 red tile barn. On the basis of temperature, steel frame and red tile barns exhibited the best effects while black plastic-film and mud barns exhibited the worse effects. Average relative humidity in different barns was in the order of： black plastic-film barn 〉 mud barn 〉 American barn 〉 red tile barn 〉 steel frame barn. Differences in relative humidity between barns and outdoors was in the order of： black plastic-film barn 〉 mud barn 〉American barn 〉 steel frame barn 〉 red tile barn. On the basis of relative humidity, steel frame and red tile barns showed the best effects while black plastic-film and mud barns showed the worse effects. There was no obvious effect of air-curing in the different barns on the quality of leaf tobacco appearance. The appearance of burley tobacco air-cured in 5 barns met high-quality standard appearance requirement. There were differences in the impacts of different barns on chemical compounds of tobacco. Except for high sugar in mud barn, chemical componefits of air-cured burley tobacco basically conformed with high-quality burley tobacco requirement. Analysis of construction cost, practicality, heat preservation and dehumidifying effects as well as the effects on chemical compounds showed that steel frame barn was most consistent with local high-quality burley tobacco requirements.
