What are the characteristics of slight cold solar terms?

The slight cold solar term is characterized by cold, but it is not extremely cold.

Slight cold is the 23rd solar term in 24 solar terms, and winter is the 5th solar term. When cold air accumulates for a long time, it becomes cold. Slight cold means that the weather is cold but not extreme. Like severe cold, intense heat, intense heat and intense heat, it is a solar term indicating temperature change. According to China's long-term meteorological records, the slight cold solar terms in the northern region are colder than the severe cold solar terms; But for most parts of the south, the big cold solar terms are colder than the small ones.

During the slight cold solar term, the East Asian trough developed the strongest and most stable, the Mongolian cold high and Aleutian low also reached the strongest and most stable, and the ridge scale of the westerly trough reached the maximum, which matched the strongest westerly intensity. The cooling process of cold air is frequent in the slight cold season, but few of them reach the cold wave standard.

Xiao Han's farming activities

Due to the large geographical span between north and south of China, different regions will have different production and cultivation for the same slight cold solar terms. In the north, in most areas, there is not much farm work in the fields, and all of them have winter holidays. The main task is to do a good job of keeping warm in vegetable pits and sheds, and to make fertilizer and accumulate fertilizer at home.

Winter fertilizer should be applied to wheat, rape and other crops in southern China, while in Hainan and most parts of southern China, it is mainly to do a good job in cold and antifreeze, store fertilizer and build water conservancy projects. Slight cold and severe cold are the periods with the least rainfall in a year.
