The electrode plate is placed at the bottommost part of the storage chamber, the second storage disc is located 4-7 cm above the electrode plate, and the distance between the first storage disc and the second storage disc is 30-35 cm. The electromagnetic device system and the illumination adjusting system simultaneously act on the fruits and vegetables, because green vegetables can be subjected to photosynthesis in a short time, the air holes of the leaves are opened, the weight loss rate is increased, and the problem of the weight loss rate increase of the fruits and vegetables can be solved by the electrostatic field generated by the electromagnetic device. The green fruits and vegetables have strong photosynthesis and are placed on the second layer of placing plate; for non-green vegetables, the effect of the electrostatic field is stronger when the vegetables are placed on the first storage plate and are closer to the electrode plate, and the weight loss rate of the vegetables and the fruits caused by illumination can be effectively reduced. Moreover, the electric field can ionize ozone generated by air, and also has the effects of sterilization and ethylene inhibition. In summary, according to the characteristic classification of fruits and vegetables, the fruits and vegetables are acted in a mode of combining electromagnetism with illumination, the shelf life of the fruits and vegetables can be effectively prolonged, the optimal preservation effect is achieved, the distance between the discharge plate 3 and the second storage plate is 4-7 cm, the electric field can exert the maximum preservation effect, the green fruits and vegetables such as spinach, lettuce, water spinach and broccoli are prevented from wilting, the weight loss rate of the vegetables and the photosynthesis is reduced, the distance between the second storage plate and the first storage plate and the light source is 30-35 cm, and therefore the beneficial illumination distance is beneficial to photosynthesis of the green fruits and vegetables in the storage period.
