The present invention is to provide a method for carbonification of crop straws and a device thereof. Pyrolysis process is controlled by regulating the feeding of oxygen during said pyrolysis process, and pyrolysis and carbonification are respectively conducted in separate pyrolysis and carbonification pools, wherein the straws are pyrolyzed in said pyrolysis pool and entered into said carbonification pool to be carbonified. The present invention can quickly raise the temperature of the pyrolysis process, shorten the time of the pyrolysis process, and improve the pyrolysis carbonification efficiency.
