Do you understand the meaning of the 24 solar terms?

Gregorian calendar every February 18 or so is a rainy solar term. At this time, the sun reaches 330 degrees of the yellow meridian, which is the solar term of "rain". Continuous spring rains often appear in February and March. This is because the cold air in the north and the warm and humid air in the south meet in Taiwan Province Province, and the front is stagnant because of its equal strength.

1. Continuous rain is a good year, and farmers don't work hard to plow their fields.

Rainy days and rainy days bode well for a bumper harvest.

2. The cold rain in spring is like spring, and the cold rain in winter is scattered.

It rains when the temperature is low in spring, and it rains less when the temperature is low in winter.

Rain, the second of the 24 solar terms, is located around the 15th day of the first month of each year (February 18-20). The sun is located at 330 degrees of the yellow meridian. On this day, the usually married daughter will go home to visit her parents and send her mother a red silk and a pot of stew. So, do you know the origin and weather characteristics of rainy solar terms? You might as well follow me yesterday to find out.

Since the Western Han Dynasty, all previous dynasties have used twenty-four solar terms to guide agricultural production, and arranged farming activities according to the solar terms, such as sowing, field management and harvesting. For thousands of years, it has been an "agricultural climate calendar" that farmers attach great importance to.

In ancient China, rainwater was divided into three stages: "One stage was that Rex sacrificed fish; Second, wait for Hongyan to come; Third, wait for the grass to sprout. " In this solar term, otters start fishing and put the fish on the shore like sacrifices before eating; Five days later, the geese began to fly back to the north from the south; In five days, in the "moist and silent" spring rain, the spirit of the sun rises everywhere in the vegetation and begins to sprout. Since then, the earth has gradually begun to show a thriving scene.

Rain not only indicates the beginning and increase of rainfall, but also indicates the rise of temperature. It was cold before it rained. After the rain, people obviously feel that spring has returned to the earth, warming bloom and being full of spring. The cold and snow time has passed in most parts of the country, and it begins to rain, which is conducive to the greening or growth of overwintering crops. Pay close attention to the field management of overwintering crops, and make preparations for spring ploughing and sowing such as seed selection, spring ploughing and fertilization. During the15th day of the rainy solar term, we went from the sixth day of July to the second day of September. "Eighty-nine swallows were planted in the ninth river in July, and cattle were plowed everywhere on September 9th and 19th." This means that most areas in the northwest, northeast and southwest plateaus are still in the cold winter, and many other areas are experiencing or have completed the transition from winter to spring under the urging of spring breeze and rain.

However, in the rainy season, cold air activities in the north are still frequent and the weather is changeable. Since we talk about the frequent cold air activities in the next season, we can't help but mention what people often say about "spring cover". This is the principle of dressing and keeping in good health put forward by the ancients according to the characteristics of spring climate change. In early spring, when the sun is shining and the climate is getting warmer, people gradually go to cotton and wear light clothes. But at this time, it is still cloudy and cold in the north, and the temperature changes greatly. Although the rainy season is not as cold as the winter, the human skin has become relatively slack, and the resistance to the evil of wind-cold will also be weakened, so it is easy to get sick by evil. So it makes sense to pay attention to "spring cover" at this time. This changeable weather is easy to cause people's mood swings and even anxiety, which affects people's physical and mental health, especially those with hypertension, heart disease and asthma. In order to eliminate these unfavorable factors, besides continuing to cover them in spring, we should also adopt positive psychological exercise methods. Maintaining emotional stability plays a very important role in physical and mental health.

After the rain, the spring breeze warms up, and pathogenic bacteria and viruses are easy to spread with the wind, so infectious diseases tend to break out in spring. Everyone should protect themselves, pay attention to exercise, enhance their resistance and prevent diseases.
