Heavy winds are frequent, and greenhouse greenhouses pay attention to reinforcement

In recent days, cold air has affected our country one after another, and the wind and cooling have become frequent visitors on the weather stage. Like No. 11, the middle and south of Hebei Province also suffered the strongest wind and dust weather since the beginning of winter. The leaves are flying all over the sky and the dust is flying everywhere. Such weather is the most unfavorable for agricultural production, especially in greenhouses. It is necessary not only to reinforce the shed film, but also to adopt some light-filling measures to compensate for the light covered by dust.
Â Â It is expected that on the 13th and 14th, a cold air will affect the middle and lower reaches of the Yangtze River and most of the areas north of it, which will not only bring about 4 to 8 degrees of cooling, but also winds of about 5 levels in many places, especially Dust or dusty weather may occur in some parts of western Inner Mongolia and North China. In case of such weather, it is necessary to minimize the time of going out to work. If you want to go out, you must also remind everyone to wear a mask and a scarf to prevent dust. On the 15th, the wind in the north will be weakened, because with The cold air moves southward, and Jianghuai, Jiangnan and South China will become the main positions for cooling. On this day, the zero-degree line of the lowest temperature will expand southward to the central and western parts of Shandong. The minimum temperature in the morning in the central and eastern regions will likely be low in innovation, and it is still very important to keep warm and cold.
The impact of cold air on the northeast region is particularly prominent, because not only is there a strong wind cooling, but the snow is also not too small. On the morning of the 12th, the depth of snow in eastern Inner Mongolia, most of Jilin, and the central and southern parts of Heilongjiang has 5 to 10 cm, and some places even have more than 20 cm. It is expected that on the 13th, there will be small to medium snow in the northeast, east of Jilin. In some places in the south of Heilongjiang, there is even a big blizzard. On the 15th, it is expected that the snow will be fine.
