The invention discloses a storage device for primary flue-cured tobacco leaves of early planted tobacco. The storage device comprises a tank and a sealable top cover. An openable air inlet hole and an openable air outlet hole are formed in the tank, the inside of the tank is divided into a plurality of accommodating platforms by netted plates, and air which flows into the tank can be freely circulated. Sandwich layers which are made of netted materials are arranged on the lower portions of the accommodating platforms, and oxygen absorbents and moisture absorbents are placed in the sandwich layers. A temperature and humidity sensor and air supply equipment are respectively electrically connected with a control panel on the outside of the tank. The storage device has the advantages that influence of external environments on the temperature and the humidity of the tobacco leaves can be relatively isolated, tobacco leaf storage environmental conditions can be artificially regulated and controlled, accordingly, the tobacco leaf storage temperature and humidity can be constantly in the optimal ranges, the tobacco leaves can be assuredly safely stored, and mellowing of the tobacco leaves can be accelerated; atomized medicaments such as insecticides can be applied to the tank, so that insect killing effects can be realized; the storage device also can be used for storing other agricultural products for short periods.
