Which areas in Shanxi will have a blue warning of frost?

There will be blue frost warning areas in Shanxi, including Datong, Xinzhou, Jinzhong, Taiyuan, Lvliang and Shuozhou. The so-called blue warning of frost is to let these areas that have issued early warning take preventive measures in advance to avoid frost on fruits, vegetables, flowers, saplings and autumn harvest. The warning was issued two days ago. In these two days, the best way to reduce losses is to take immediate action and take preventive measures. Frost warning is an early warning of sudden drop in temperature. It means that the temperature will drop directly from a dozen degrees to below zero. Obviously, this drastic cooling will cause very fatal damage to crops. Issuing early warning is of positive significance and can recover most of the losses.

After the blue frost warning is issued, departments at all levels, especially the competent departments of agriculture and forestry, should temporarily return to their jobs and urge farmers to do all kinds of protective work. Frost came earlier, so it did have a great impact on many fruits and vegetables. Especially at night, the temperature will be the lowest. At this time, how to protect crops from damage depends on intervention measures. Measures to prevent frost are:

1, smoking

If you want to relieve frost, smoking is very effective. Pay attention to fire prevention when smoking. This warning also warns of windy weather. Smoking time should be chosen properly, and 2 am is better.

Step 2: Spray water.

The so-called water spraying method is to lower the temperature of crops first, so that when there is frost, the water vapor will release heat and the frost can be alleviated.

3. Swamp

The main principle of wetland method is to increase the heat capacity and thermal conductivity of soil, so that frost can be alleviated to the greatest extent.

4. News reports

The most commonly used method is covering method, which can use straw curtain or film.

Step 5 wash the cream

If it is too late to take measures before the frost, the crops have been frozen. In this case, the crops can be sprayed with water before sunrise, and the frost can also be alleviated.
