The present invention belongs to the technical field of fruit and vegetable preservation and particularly discloses a method for storing and preserving fruits and vegetables. The method comprises thefollowing steps: (1) picked fresh fruits and vegetables are sorted and graded, then the sorted and graded fruits and vegetables are separately placed in slightly acid electrolyzed water for ultrasonicwashing, wherein the washing temperature is set at 35-50 DEG C, the time is 8-10 min, and the power is 500-600 W, and then the fruits and vegetables are taken out to be drained; (2) the drained fruits and vegetables are placed in a low-voltage electrostatic field device, wherein the stacking height of the fruits and vegetables is 1-3 layers, and the fruits and vegetables are treated in an electric field with an output voltage of 2.5 kV/m and a current of 0.2 mA for 120-180 min; and (3) the fruits and vegetables treated by the electric field are soaked in film coating liquid for film coating treatment, after drying, th
