The invention relates to an over-ground type ventilated warehouse of oranges. The over-ground type ventilated warehouse is composed of over-ground buildings including a warehouse roof, rainproof and windproof covers, a water wall, a buffering room, an upper wind inlet, an upper and lower ventilation window opening/closing power system selective control device, a storage room, a water discharging pipe, a water seepage pipe, an underground ventilation channel, lower ventilation windows, upper ventilation windows, a buffering room roof, a water tank, a double-layered roof of the storage room and the like, which form a working system device. The warehouse is divided into the storage room and the buffering room, and the buffering room sleeves one side of the storage room. The four rainproof and windproof covers are arranged at the top of the warehouse; a western wall surface is the water wall and is used for keeping suitable humidity in the storage room; the four upper ventilation windows are arranged above southern and northern vertical surfaces of the storage room, and the four lower ventilation windows are arranged under the wall body; a ventilation fan is arranged among the upper ventilation windows; a storage platform is arranged in the storage room; two indoor humidification air flues are formed by the water seepage pipe and the water wall under the storage platform and the suitable storage humidity of the oranges is kept, so that the preservation period of the oranges is prolonged. The opening and closing of the ventilation windows are selectively controlled by a power system.
