Study on the Flue-Curing Processes in the Intensive Curing House Suitable for the Harvesting at One Time of Six Middle Leaves of Paddy-Tobacco
To provide reference for the formulation of rice stubble flue-cured tobacco curing technology,bulk curing barns technology suitable for one-time harvesting of six leaves in the middle of flue-cured tobacco in rice stubble was clarified.The effects of four-step curing technology(T1)and medium temperature and medium humidity curing technology(T2)were compared and analyzed with Yunyan 87 middle leaves as experimental materials.The results showed that,the average values of appearance quality index,physical characteristics index,total score of smoking quality and comprehensive quality index of tobacco leaves after T1 treatment were 0.81%,3.89%,7.99%and 4.57%,higher than those of T2 treatment;availability index of chemical components was 4.29%lower than that of T2 treatment.Starch content of the four-step curing technology was slightly higher than that of T2 treatment,but the chlorogenic acid content was 14.18%higher than that of T2 treatment.The fine tobacco ratio of the T1 treatment increased by 4.62%,the fuel cost decreased by 11.17%,and the total energy consumption cost decreased by 9.35%.The four-step curing technology can improve the quality,high quality tobacco leaf and average price of six middle leaves of flue-cured tobacco in rice stubble after one-time harvest,reduce the curing costs,and possesses certain promotion value.
