The freezing damage of fruit trees during flowering will affect the flowering pollination and fruit setting rate of fruit trees. Feng Jianzhong, a researcher at the Shijiazhuang Fruit Research Institute of the Hebei Academy of Agricultural and Forestry Sciences, said that the sooner the remedy is, the better the effect will be after the weather recovers. After the fruit trees are damaged by freezing, the tree body is weak, the resistance to stress is poor, and pests and diseases are prone to occur. It is necessary to strengthen the integrated prevention and control of pests and diseases and reduce the economic losses caused by pests and diseases.

Experts believe that the flowering period is frozen, and the growth regulator such as gibberellin is sprayed in the absence of the receptacle to promote firmness and reduce yield loss. One or two times of artificial pollination of lightly frozen flowers, or spraying of 0.3% borax + 0.5% sucrose solution, or spraying 0.2% of molybdenum fertilizer, all have the effect of reducing freezing damage and increasing fruit setting rate.

Wang Yanbin, head of the Agricultural Economics Section of the Agriculture Bureau of Xingtai City, said that the recent low temperature weather has little effect on wheat and other field crops, because the wheat body is low and will not cause lodging. If the vegetable facility is damaged, the damaged shed film should be repaired in time; the fruit tree should focus on the flower preservation and fruit preservation, and spray the compound foliar fertilizer in time.
