What is the first of the 24 solar terms?
Dormancy is the third solar term in a year, marking the beginning of the mid-spring season. In the season of fright, some parts of China are already in the season of peach blossom red, plum blossom white, orioles singing and swallows coming, and most areas have entered the spring ploughing season. There is a proverb that says, "If you are surprised, it will be warm and harmonious, and the old toad will sing folk songs.
Amazing solar term climate
1, spring thunder
Spring thunder often refers to the first thunder in a year. Spring thunder rings and spring returns to the earth. It is the product of cold and warm air meeting, atmospheric instability and convective weather. Farmer friends are very concerned about the time when the spring thunder first sounded. If the first thunder sounds on the day of thunder, you will think that the crops will be in good weather that year; If the first thunder before the fright, it means that there was more rain in that year, and there may be "continuous spring rain"; On the contrary, there may be drought.
2. cold spring
During the period of fright, it was warm and cold, and farmers in the south were most worried about "low temperature and rainy weather". At this time, warm crops such as early rice and cotton in South China and South Jiangnan began to sow and raise seedlings. In low temperature and rainy weather with average daily temperature ≤ 10℃ for three consecutive days or more, insufficient light will cause early rice to rot; This kind of weather is also extremely unfavorable to the sowing and management of rape, cotton and corn; It is also very harmful to jointing growth of winter wheat.
3. Spring drought
The northern land began to plow in spring, and people were most worried about the spring drought caused by too little rain. The north is known as "spring rain is as expensive as oil" and "spring drought in nine years". At this time, there are still snowflakes falling in the north, but for the relatively dry northwest and northeast, the snow at this time is very conducive to the increase of soil moisture. If there is decent rain and snow, it is very beneficial to spring sowing production and winter wheat turning green as soon as possible. During this period of time in North China, even if there is snow, it often appears in the form of sleet, and it often falls to the ground in the form of rain.
Is it spring after the solar term?
Twenty-four solar terms, divided by season, happen to have six solar terms in each season. Every year, the solar terms start from beginning of spring, the first six solar terms are spring solar terms, and the third solar term in a year is fright, that is, fright is spring solar terms. However, in astronomy, when the solar terms suddenly appear, spring has arrived, not beginning of spring. Astronomically speaking, beginning of spring is in beginning of spring, but climatically speaking, beginning of spring needs an average temperature above 10℃ for five consecutive days. In most areas, the average temperature of the scary solar term is 12℃ to 14℃, which is more than 3℃ higher than that of rain, and it is the solar term with the fastest annual warming. The sunshine time has also increased significantly. However, due to the alternation of cold and warm air, the weather is unstable and the temperature fluctuates greatly. The temperature in the warning period of most years in the Yangtze River basin is stable above 65438 02℃, which is beneficial to the sowing of rice and corn. The average daily temperature in other areas is lower than 12℃ for more than three consecutive days, so it is not allowed to sow blindly early. Although the temperature rises rapidly, the increase of rainfall is limited. The total rainfall in central and northwest South China is only about 10 mm, and spring drought often begins after winter drought all the year round.
Three stages of fear
Wait a minute, the peaches will begin to bloom. On the frightened day, the peach began to blossom, and the peach died, burning its flowers. It was the beginning of spring, peach blossoms were delicate, willow leaves were born, and flowers were blooming. In the scary season, Rosaceae plants such as apple blossom, peach blossom, rose and cherry blossom are in full bloom, among which peach blossom and cherry blossom are the most brilliant.
Wait, pale Geng Ming. After five days of fright, "Cang Geng Ming" turned into an oriole. The oriole first felt the breath of spring, sang its songs and asked its friends. The birds sang and sang, which was also a celebration of spring flowers.
Third, the eagle became a pigeon. On the fifth day, "eagle becomes pigeon". The ancients called "pigeons" cuckoo birds. In mid-spring, because the beak is still very soft, I can't catch birds, and I am so hungry. In autumn, pigeons become eagles again.
