What are the characteristics of the great cold solar terms?

Severe cold is the period with the least rain in a year.

The great cold is between March 9 and April 9. At this time, the cold wave frequently goes south, which is the coldest season of the year and the period with the least rainfall. There is a folk saying that "a slight cold is the most important thing, and it is cold without wind." Great cold refers to extremely cold weather. This is a season where vitality lurks and everything is hidden.

Because China has a vast territory and a large span between the north and the south, the climate between the north and the south is quite different. According to China's long-term meteorological records, there is no slight cold in the great cold solar terms in the northern region; But for some coastal areas in the south, the coldest is in the great cold solar terms.

Agricultural changes in severe cold

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 winter, the northern region is covered with snow, so it is almost impossible to grow crops.

In most areas, there is not much farm work in the fields, and all of them have winter holidays. Slight cold and severe cold are the periods with the least rainfall in a year. The southern region should pay attention to applying winter fertilizer to wheat, rape and other crops, and do a good job in cold and antifreeze and water conservancy construction.
