The invention discloses a system for adjusting the oxygen concentration in a tobacco leaf sealed cargo stack in the technical field of tobacco leaf mellowing maintenance. The system comprises a sealed sleeve bag, and the sealed sleeve bag covers the outer side of the tobacco leaf cargo stack; the data acquisition module is used for acquiring temperature and humidity information and oxygen concentration information of the tobacco stack; the nitrogen supply module is used for conveying nitrogen into the sealing bags; the one-way exhaust valve is arranged on the sealing sleeve bag and can exhaust gas in the stack to reduce pressure; and the terminal control module is in electric signal connection with the data acquisition module and the nitrogen supply module, and is used for receiving the temperature and humidity information and the oxygen concentration information and controlling the nitrogen conveying amount of the nitrogen supply module into the sealing bag. According to the method, the automation level of c
