What are the climatic characteristics of slight cold?

The climatic characteristics of slight cold are as follows:

During the slight cold season, most parts of China have entered a severe cold period, with frozen soil and rivers frozen. In addition, the cold air in the north continues to go south and the weather is cold. People call it "counting nine cold days"

Although it is not as cold in the south of our country as in the north, the temperature has dropped obviously. The coldest time in the south is slight cold, between rain and fright. It is dry and cold when it is a little cold, and it is wet and cold after the rain.

The slight cold has arrived, wheatgrass is hidden, and the earth is dormant, waiting for the spring return. "Twenty-four solar terms" said: "Slight cold, December Festival. The cold was still small at the beginning of the month, so it was cloudy. It will be big in half a month. " There are three stages of slight cold: one stage, Yanbei Township; Second, magpies began to build nests; Third, the pheasant begins to grow. Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme.

There is a folk saying in our country that "the cold is in March 9th", but the March 9th in the middle of winter is basically in the solar terms of slight cold. As the saying goes, "the north wind blows in cold days, and the slight cold is on February 30th", so there is a saying that "slight cold is better than severe cold".

Agricultural activities needed in slight cold season

In the northern region, there is not much farm work in most areas during the slight cold season. The main task is to make a good vegetable pit, keep the barn warm, make fertilizer and accumulate fertilizer at home.

In the southern region, attention should be paid to topdressing winter fertilizer for wheat, rape and other crops; In Hainan and most parts of South China, it is mainly to prevent cold and frost, accumulate fertilizer and build water conservancy projects. In case of strong cold air, plant ash, crop straws or manure are scattered on the ground to help crops spend the coldest season.
