The impact of this round of widespread cooling and snowfall in the north on agricultural production has both advantages and disadvantages. On the one hand, snowfall is good for agricultural production. In the northern winter wheat region, most of the wheat is still in the overwintering period and has strong cold resistance, and the snowfall has effectively replenished the soil moisture, which is beneficial to the safe wintering of wheat. At the same time, snowfall is also conducive to improving soil moisture and providing good water conditions for the subsequent growth of wheat. In addition, facility agriculture also benefits from snowfall, and the snow cover on the facility greenhouse, which can play a role in heat insulation, reduce heat loss in the shed, and facilitate the growth of facility vegetables. 
On the other hand, cooling and snowfall also have a detrimental effect on agricultural production. Cooling may cause the temperature in the greenhouse to drop, affecting the growth rate and quality of vegetables. At the same time, snowfall may lead to excessive snow accumulation in the facility greenhouse, increasing the load-bearing burden of the greenhouse, and if the snow is too heavy, it may lead to the collapse of the greenhouse, resulting in damage to the facility and damage to vegetables. In addition, after snowfall, there may be disasters such as freezing and frost damage, which will adversely affect agricultural production. 
The impact of this round of large-scale cooling and snowfall in the north on agricultural production has both advantages and disadvantages, and it is necessary to pay close attention to weather changes and take corresponding management measures to ensure the smooth progress of agricultural production. In order to ensure the smooth progress of agricultural production in the case of large-scale cooling and snowfall in the north, the following management measures can be taken: strengthen the thermal insulation work of facility agriculture: for facility greenhouses, the thermal insulation performance of the greenhouse should be checked in advance, and the damaged parts should be repaired in time to ensure the sealing of the greenhouse. At the same time, thermal insulation facilities can be added in the greenhouse, such as thermal insulation quilts, stoves, etc., to increase the temperature in the greenhouse and ensure the normal growth of vegetables and other crops. Remove snow in time: After snowfall, the snow on the greenhouse should be removed in time to prevent excessive snow from increasing the load-bearing burden of the greenhouse and causing the greenhouse to collapse. At the same time, snow should be cleared from the fields to prevent the breeding and spread of diseases. Do a good job of agricultural cold protection: For open-field crops, measures such as covering straw and plastic film can be taken to prevent crops from freezing. At the same time, the cold resistance of crops can be improved by increasing organic fertilizer, phosphorus and potassium fertilizer. Strengthen pest control: After cooling and snowfall, crops are susceptible to pests and diseases. Therefore, the monitoring and prevention and control of pests and diseases should be strengthened, and the problems of pests and diseases should be discovered and dealt with in a timely manner to prevent the spread and spread of diseases. Do a good job in agricultural insurance: Agricultural production is facing the risk of natural disasters, and agricultural insurance can be purchased to reduce the losses caused by disasters. After a disaster occurs, contact the insurance company in time to make a claim to protect the interests of farmers. In short, in order to ensure the smooth progress of agricultural production in the case of large-scale cooling and snowfall in the north, it is necessary to pay close attention to weather changes, take corresponding management measures, strengthen the insulation work of facility agriculture, remove snow in time, do a good job in agricultural cold protection, strengthen the prevention and control of pests and diseases, and do a good job in agricultural insurance. These measures can help farmers cope with natural disasters and ensure the stability and sustainable development of agricultural production.
