The utility model discloses a simple burley tobacco air-curing barn. The problems that the existing air-curing barn occupies large space and cannot move, crop rotation on tobacco fields is limited, and scale development on air-curing of tobacco leaves is restricted are mainly solved. The simple burley tobacco air-curing barn comprises a cuboid-shaped air-curing barn body (1), tobacco hanging beams (2) and a lagging jack (3), wherein wood plates are detachably connected to one another to form the cuboid-shaped air-curing barn body (1); the tobacco hanging beams (2) are arranged in the middle of the air-curing barn body (1) in the transverse direction; the lagging jack (3) is arranged on the top of the cuboid-shaped air-curing barn body (1); black cover films cover the lagging jack and the periphery of the air-curing barn body; the top black cover film is fixedly connected with the air-curing barn body; the tobacco hanging beams and the lagging jack are detachably connected with the air-curing barn body; the wood plates, which are arranged above the tobacco hanging beams, on two sides of the air-curing barn body are ventilated gratings (4); a temperature and humidity detector is also arranged in the air-curing barn body; and a temperature and humidity temperature displaying screen which is connected with the temperature and humidity detector is arranged on the outside of the air-curing barn body. The simple burley tobacco air-curing barn is simple in structure, reasonable in design, low in cost and convenient to implement.
