The method is characterized by comprising the following steps: (1) precooling treatment of celery, (2) antistaling agent preparation, (3) precooling, (4) packaging by a food grade polyethylene film, and (5) stagewise cooling refrigeration storage. Through addition of the antistaling agent and stagewise cooling in storage, the celery can slowly adapt to the increasingly lower temperature and gradually reduce the sensitivity to low temperature, so as to greatly reduce the probability of chilling injury of the celery, keep the advantages of crisp roots, tender stems and sufficient moisture of the celery, maintain the taste and quality of celery, and extend the preservation time.
