What do you know about the Great Cold?

What do you know about the Great Cold? This handwritten newspaper is as follows:

"Great Cold" is extremely cold in a year. The great cold from winter to the 36th day in the future is also called "Sikuya sleeps like camping", which means extremely cold. Like slight cold, great cold is also a solar term representing the degree of cold weather. Modern meteorological observation records show that in most parts of China, severe cold is not as good as mild cold. However, in some years and a few coastal areas, the annual minimum temperature will still appear in the severe cold solar terms.

In the severe cold season, the average temperature in most parts of southern China is 6℃ to 8℃, which is nearly 65438 0℃ higher than slight cold. The proverb "slight cold and severe cold, cold into a ball" shows that the severe cold solar term is also a cold period of the year. Therefore, it is necessary to continue to do a good job in the cold protection of crops, especially to protect livestock from wintering. For some crops, a proper low temperature is necessary in a certain growth period. Wheat and rape with strong winterness need lower temperature through vernalization stage, otherwise they cannot grow and develop normally.

Customs around the Great Cold:

During the severe cold season, there is still less farm work in various places. People in the north are busy accumulating fertilizers and compost to prepare for spring; Or strengthen the cold and antifreeze of livestock. In the southern region, the field management of wheat and other crops is still strengthened. People all over the country also use the change of the cold climate to predict the rain and grain abundance in the coming year, which is convenient for arranging farming as early as possible. For example, "It rains when it is cold, and it rains a lot in February and March" (Guangxi).

"Seeing three whites in the cold, farmers have plenty of food and clothing" (Jiangxi), "It is not cold in the cold, and people are uneasy" (Fujian), "Snow in the cold will set a bumper year" (Guizhou), and "There is no wind and drought in the cold". ? After the slight cold, 15 is a severe cold, which is also the last of the 24 solar terms in the whole year. Although the weather is cold at this time, it will not be as cold as it is from heavy snow to winter solstice because it is near spring.

At this time, people are busy throwing away old decorations, pickling new year's dishes and preparing new year's goods, because the Spring Festival, the most important festival for China people, is coming. Northerners also have a very important day, Laba, which is the eighth day of the twelfth lunar month. On this day, people cook a pot of sweet and delicious Laba porridge with whole grains, peanuts, chestnuts, red dates and lotus seeds, which is an indispensable staple food for people in the New Year.
