Abstract：To improve the curing quality, the temperature and humidity in different barn space and at different curing time were measured by HE174 automatic temperature and relative humidity recorder in airflow-descending bulk curing barn.The results showed that there were some differences in temperature and relative humidity in the upper, middle and lower layers and the different zones of plane areas during the curing process.The changes in the vertical and horizontal directions were smaller at the early yellowing stage, were larger at the later yellowing stage and leaf-drying stage, and gradually reduced at the stem-drying stage.The difference of temperature and relative humidity in the vertical direction was significantly larger than that in different areas of the horizontal direction.The chemical composition of tobacco leaves was different between different layers after curing.The difference of nitrogen compound content was smaller.The content of total sugar and reducing sugar in the lower layer was slightly higher than that in the upper layer without significant differences.The results could provide the theoretical basis for guiding the reasonable tobacco-loading and optimizing the curing technology for bulk curing barn.
