Abstract: In order to resolve how to stack the tobacco leaf in the loading room, the loading technology of loose tobacco curing barn were studied by adopting the method of flashboard and natural. The results showed that the loading technology could be better when adopting natural stacking method, and pushing slightly, while the loading density keeping at 75-85kg/m3. We also bring forward the key point of harvesting and loading. The lower leaf should harvesting earlier, the cutter should harvesting in mature, while the upper leaves should harvesting when it completely ripe. When loading, the tobacco leaves should lay in order, and its frontispiece face the man who was loading, keep the included angle 70~80° in the leave and the loading board, layer on layer.
