In this study, Yongzhou tobacco HY-9-7, clouds 87 K326 three cultivars of different baking process under the curve , grilled reducing sugar of tobacco , nicotine, chlorine, total nitrogen, potassium , starch and other internal chemical Determination of the composition , combined with the cost of each treatment baking , and compares the cured leaf quality and appearance of the economic value of the best baking process to explore various varieties ; comparison of nine different types of bulk curing barn comparison test, explore the most suitable Yongzhou tobacco-growing areas of dense the barn type ; intensive barn renovation , Additions forced ventilation hot air circulation system , combined with the baking process suitable for Yongzhou smoke to be promoted , Yongzhou tobacco leaves yield and quality has been greatly improved . The results showed that : 1 , HY - 9 - 7 lower part of the leaf dry bulb temperature 38 ° C , wet bulb temperature to maintain 36 ° C , tobacco yellow 7 , leaves softened , the main vein 1/2 softened , dry bulb temperature of 45 ° C before the wet-bulb temperature stabilized at 38 ° C ; middle leaves in the dry-bulb temperature of 38 ° C , wet bulb temperature to maintain 36 ° C , tobacco yellow 9 , the leaves become soft , the main vein 1/3 softened , dry bulb temperature of 45 ° C before wet bulb temperature stabilized at 38 ° C ; upper leaves in the dry-bulb temperature of 38 ° C , wet bulb temperature to maintain 37 ° C , the tobacco basic yellow leaves soften , the main vein 1/3 softened wet bulb , dry bulb temperature 45 ° C before cured leaf temperature stabilized at 39 ° C , and overall performance . Clouds 87 and K326 in an appropriate increase given the color of the wet-bulb temperature , improve the baking quality of the tobacco to reduce the upper leaves microstrip smoke generated , the superior tobacco ratio and the average price of lower leaves and upper leaves so as to deal with a higher , upper-middle- middle leaf tobacco ratio and average price higher to deal with , but the difference was not significant ; the energy consumption baking Yunyan87 slightly lower but a slight increase in K326 ; nine different types of bulk curing barn comparison test , cured leaf , the upper leaf economic traits , chemical composition and appearance quality , combined with the cost of baking , to conclude , as the most suitable YZ - 1 the Yongzhou tobacco bulk curing barn . Combines three varieties process test and barn type comparison test , the barn has been transformed , the test proved Additions forced ventilation hot air circulation system , reduce the baking room horizontal and vertical temperature difference was beneficial change yellow and fixative cured leaf , full color coordination , chemical composition , aroma and taste of improved availability improved .
