Before the arrival of the storm, it is necessary to check the fixing of the plastic film. The lamination line or pressure bar must be firmly fixed and the grass bead must be tightly closed. Such weather can be expedited as soon as possible, but it must be emphasized that, in the case of continuous snowfall, the time for exposing each day cannot be less than 4 to 5 hours. Although this kind of weather does not have direct light, it can increase the temperature by scattering light. After a short period of time, the temperature drops, but generally it is 3 to 4° C. higher than that of uncovering after 30 minutes.
Livestock husbandry should pay attention to keeping livestock warm, feed reserves and other work to prevent the adverse effects of strong winds, cooling, and snowfall. For example, on the sheds of cattle and sheep, plastic membranes or rice straws can be used to block and prevent draughts. At the same time, it is best to put dry straw on the inside of the shed to keep warm, and to care for young and frail animals, to ensure that the room temperature reaches 15 To 18 degrees. In addition, the civil structure of the barn should be reinforced, remove the snow on the roof, to prevent the collapse of the barn.
North winter wheat areas should pay attention to nurturing strong seedlings to prevent freezing damage. The northern winter wheat area must pay close attention to the changes in the weather, timely fertilization and watering according to the cooling conditions and wheat field moisture conditions to promote the formation of strong seedlings and prevent freezing damage. For fields with insufficient moisture (less than 12% soil moisture in the 0- to 10-cm soil layer during the three-leaf stage), the daily average temperature should be stable at 3°C ​​to 4°C, that is, the soil should be irrigated and the winter water be irrigated. The seedlings must be poured first, and the de-fermentation seedlings must be poured. Afterwards, sufficient seedlings can be poured on the bottom of the seedlings. Can be combined with adequate amount of winter irrigation water, but the amount of nitrogen should not be too large, generally 3-5 tons of urea per acre or ammonium bicarbonate 10 to 15 kilograms; for the lack of phosphorus, potash or phosphorus, potassium lack of fields, It is also possible to apply appropriate amounts of phosphorus and potassium fertilizers before irrigation.
In addition, meteorologists reminded the public to prevent wind, cold, and traffic safety and reduce unnecessary outdoor activities; the government and relevant departments do a good job in preventing snowstorms and freezing, and pay special attention to strengthening inspections of roads, power facilities, simple buildings, and trees. Maintenance, especially the use of tree-supported transmission lines, to do road cleaning and snowmelt work.
