After the occurrence of frost damage, it should be watered in time. Watering can increase the heat capacity of the soil, stabilize the air temperature in the surface and the shed, inhibit the decrease of ground temperature, and effectively reduce and control the development of frost damage. The amount of water to reach the plough layer is appropriate, and should not flood flooding, so as to avoid the low temperature and humidity caused the roots of vegetables. After shed vegetables are frozen, they cannot be immediately heated in the shed. If the temperature is too high, the frozen tissue will dehydrate and die. The correct method is to reduce the air temperature, so that the greenhouse temperature slowly rises, so that the frozen tissue fully absorb water, promote cell revival and reduce tissue death. After freezing damage occurs to the shed vegetables, the frozen stems and leaves should be cut in time to avoid moldy lesions and induced diseases in the frozen tissues. Covering the shade in the shed can prevent the frozen vegetables from losing water due to direct sunlight. The combination of watering of the frozen plants can be followed by appropriate amount of quick-effect fertilizer, which can improve the nutritional status of the crop, enhance the cold-resistant and anti-freezing ability of the plants, and promote the early recovery of the plants. Foliage spraying is more efficient than soil dressing and fertilizer efficiency, and reasonable spraying should be performed according to the characteristics of different crops. It is better to add appropriate amount of gibberellin when spraying foliar fertilizer. After the plants are frozen, the pests and insects can easily enter the house. Sprinkle some protective agents and pest control insecticides in time.
