What does the vernal equinox mean?

English translation of vernal equinox: vernal equinox

Minutes mean equal parts, and vernal equinox means equal parts day and night.

At the vernal equinox, fingers fight. The meridian of the sun is 0 degrees. The sun is above the equator at the vernal equinox. This is the 90-day vernal equinox of spring. On this day, the northern and southern hemispheres are equal in day and night, so it is called the vernal equinox. After this day, the direct position of the sun moves northward, and the days in the northern hemisphere are long and the nights are short. So the vernal equinox is the beginning of spring in the northern hemisphere. Overwintering crops in most parts of China have entered the spring growth stage. Agricultural proverbs in various places include: "The spring equinox comes first, and rice competes for money" (Guangdong), "The spring equinox never stops raining, but the summer equinox never stops burning" (Sichuan), "When it rains, every family is busy, planting melons and beans first, then transplanting them" (Hubei), "Planting vegetables at the spring equinox, picking melons in summer" (Hunan) and "Planting beans at the spring equinox, and planting them at the autumn equinox.

The mysterious (yuan) bird arrives: Yan Laiye.

Thunder is the sound: thunder is the sound of yang, and it can't go out in the shade, so thunder is exciting.

First electricity: electricity is the light of the yang, the light is invisible when the yang is weak, and the yang is restrained in the yin. Its light is hair, so it begins to lightning.

Introduction of vernal equinox

The vernal equinox is one of the solar terms reflecting the changes of the four seasons. In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter were used to indicate the beginning of the four seasons. The vernal equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season. On the vernal equinox, the sun shines directly on the equator, and the time between day and night is equal all over the earth. Therefore, the ancient vernal equinox and autumnal equinox are also called "equinox", and there is a folk proverb that "vernal equinox and autumnal equinox are equally divided day and night". After the vernal equinox, the overwintering crops in most parts of China entered the spring growth stage. There is an agricultural proverb in Central China, "Wheat starts at the vernal equinox, and every moment is worth a thousand dollars". The temperature in all parts of our province continues to rise, but it is generally not as fast as the spring equinox. In late March, the average temperature in the north of the basin was mostly 13℃ to 15℃, and in the south of the basin was mostly 15℃ to 16℃. Most of the plateau has been melted by snow, and the ten-day average temperature is about 5℃ to 10℃. The temperature in the valley areas such as Jinsha River and Anning River in the southwest of our province is the highest, with an average of 18℃ to 20℃. Except in marginal mountainous areas, the average daily temperature in the basin has steadily increased to above 65438 02℃ in the past seven or eight years, which is beneficial to planting crops such as rice and corn, and is also very suitable for afforestation. However, before and after the vernal equinox, strong cold air often invades the basin, and the temperature drops obviously, and the lowest temperature can be as low as 5℃. Sometimes a small stream of cold air comes one after another, forming a low temperature and rainy weather that lasts for several days, which is not good for agricultural production. According to this feature, we should make full use of the weather forecast, grasp the cold tail and warm head, and sow in time.
