Which solar term is the rain in front of and above?
"Stunned" season, the third of the 24 solar terms. On March 5 or 6 every year, when the sun moves to 345 degrees of the Yellow Meridian, it is a "fright". It means that the weather is getting warmer, and there are gradually spring thunder, which awakens the insects that are dormant and hibernating underground. From the day of the "fright", most parts of China entered the spring ploughing season. Although the weather gets warmer in the "fright" season, cold air activities are still frequent. When the temperature is high and low, it is cold at first, especially when the temperature difference between morning and evening is large, we should pay attention to keep warm and prevent diseases. "Spring thunder scares thousands of insects", and the warm climate conditions are conducive to the occurrence and spread of many diseases and insect pests, and weeds in the fields are also sprouting. Therefore, pest control and intertillage weeding should be done in time. "Peach blossoms are coming, swine fever is coming", and the epidemic prevention of poultry and livestock should also be paid attention to. At this time, the temperature rose rapidly, and spring thunder gradually appeared in most areas of the Yangtze River Basin. Beginning of spring is not only the first of the 24 solar terms, but also an important festival. Astronomically speaking, it marks the beginning of spring. On February 4th or 5th every year, when the sun reaches longitude 3 15, it is beginning of spring.
The understanding of beginning of spring is explained in the ancient book Qunfangpu: "Li, Jian also. Spring began and was established. " During the early spring, the temperature, sunshine and rainfall began to rise and increase. But all this is just a prelude to spring in most parts of the country, and the prelude to spring has not really begun. Since the Qin Dynasty, beginning of spring has been the beginning of spring in China. Beginning of spring is divided from astronomy, but in nature and people's minds, spring is warm and flowers are fragrant. Spring is growth, cultivation and sowing. In climatology, spring refers to the period when the average temperature is between 10℃ and 22℃.
