What grass grows after the twenty-four solar terms?

No matter what grass grows in the twenty-four solar terms, because the last solar term of the twenty-four solar terms is severe cold, which belongs to winter, and no grass grows in winter.

The Great Cold is the last of the twenty-four solar terms, and it is called "Great Cold" when the sun reaches 300 degrees of the yellow meridian around 65438+1October 20th every year. Great cold refers to extremely cold weather. Time-sharing, time-sharing, time-sharing and time-sharing quote three ritual meanings: "Great cold is the middle, and the upper form is slight cold, so it is called great cold ... extremely cold, so it is called great cold."

At this time, the cold wave frequently goes south, which is the cold period of the year in most parts of China. The wind is strong, the temperature is low, and the snow on the ground does not melt, showing a cold scene of ice and snow. The poem says: "The wax trees are shady and the mountains are bright, and the north wind roars the three rivers alone. The old farmer still likes Gao Xue, and it will taste like wheat in the coming year. (Heshui Zuo) "The Great Cold is the last of the 24 solar terms in China. After the severe cold, beginning of spring will usher in a new year's solar cycle.

During the severe cold solar term, the atmospheric circulation is relatively stable, and the adjustment period of circulation is about 20 days. This circulation is calm, and when learning to adjust, there will often be a wide range of rain and snow weather and strong winds to cool down. When the west of 80 degrees east longitude is a long wave ridge and East Asia is a coastal trough, under the influence of northwest wind flow control and constantly supplemented cold air, China will have a sustained low temperature.

Like slight cold, great cold is also a solar term indicating the degree of cold weather. Modern meteorological observation records show that in some areas of China, severe cold is not as good as slight cold, but in some years and a few coastal areas, the annual minimum temperature will still appear in the severe cold solar terms. Therefore, it is necessary to continue to do a good job in the cold protection of crops, especially to protect livestock from wintering.
