How much damage has the heavy snow done to crops this year?

Unlike the annual snow in the north, this cold wave has a great impact on crops and agricultural production in the south. Vegetables still growing in the fields in some places in the south are frozen to death, and the growth results of some southern fruit trees in the second year will also be affected, and the flowering period of flowers will be delayed. ...

Hazards: 1, chilling injury and freezing injury. Low temperature affects the growth of crops and even causes tissues to freeze and die. 2. Long-term low temperature and rainy weather make the light insufficient, and plants can't synthesize and accumulate nutrients. 3. The increase of humidity increases the probability of disease.

Advantages: increase soil moisture and alleviate drought; Low temperature kills pests, and pests may decrease next year; It is beneficial to the sales of winter vegetables in Hainan and western Guangdong.
