According to the forecast of the Central Meteorological Observatory, on the 15th to 19th, there will be a cold air affecting most parts of northern China, with a cooling temperature of 4-6 °C, in which the eastern part of Inner Mongolia and the northeastern part of Northeast China will be cooled by 8-10 °C, accompanied by 4- Level 6 wind; this cooling weather may have an impact on facility agriculture, so it is necessary to prevent and ensure safe agricultural production.
In the event of strong winds and cool weather, the sheds that are being produced should not be drowned, and dehumidification should be carried out in the fields, such as planting ash, rice and wheat, etc., and prolonging the ventilation and dehumidification time. All the west walls of the greenhouse are compacted with soil bags to ensure that the laminating line is 1.5 meters. The pillars in the shed are protected from the wind and damage to the greenhouse infrastructure. Prepare candles, small coal stoves, etc., and prepare warming equipment such as heaters in conditional conditions for use during nighttime during cooling. Cover the old shed film and grass mites to prevent the occurrence of freezing damage; the sheds with smaller seedlings can be covered with arch sheds or sterilized aerosols or grass smoke at night to prevent freezing and cold protection. Selecting the foliage of the plant on the sunny day to spray the foliar fertilizer can play a role in enhancing the stress resistance.
