Abstract: To enhance the leaf quality of flue-cured tobacco, the trials were studied by the tobacco loading chamber sanded of bulk curing barn in Changting County of Longyan City in Fujian Province. The results showed that it was not significant for the humidity of bulk curing barn in the yellowing stage between the contrast and the treatment. However, in the color fixing stage, the humidity of the barn was over between 1℃ and 3℃ in the tobacco loading chamber sanded than the tobacco loading chamber. And the leaf quality of flue-cured tobacco was significantly enhanced by sand. Besides, the energy consumption was similar between them. Thus, the study suggests that it is a very good measure to enhance leaf quality of flue-cured tobacco by sand in tobacco loading chamber of bulk curing barn.
