Spring equinox health care
The vernal equinox festival details the earth at 5:48:46 every 365 days. It revolves around the sun for a week and rotates every 24 hours.
Since the orbital plane of the earth’s rotation is not consistent with the equatorial plane, it still maintains a certain inclination, so the position of the sun’s direct light to the earth is different throughout the year.
In the northern hemisphere, the sun is directly at 23 latitude.
At 5 degrees, the astronomical name is called the summer solstice; the sun is directly at the south latitude 23.
The 5th degree is called the winter solstice; the summer solstice and the winter solstice mean that it has reached the middle of the summer and winter seasons.
When the sun is shot twice on the equator twice a year, it is the spring equinox and the autumn equinox. This is the middle of the spring and autumn seasons. The two days are as long as the night.
”4:8″, in the twenty-four solar terms, the spring equinox is one of the basic solar terms.
“Spring equinox, yin and yang are also half.
Therefore, staying up all night and cold and flat.”
A “point” word tells the boundaries of staying up late, the heat of summer.
At this time, the sun yellow is 0 degrees, and the sun is above the equator.
The Lunar Calendar records that “the bucket refers to the spring equinox, and it is about Sundays. The north and south hemispheres are equally divided into the night and the night, and they are called the spring equinox.
“The ancient habits were to establish spring, stand in summer, stand in autumn, and stand in winter to express the beginning of the four seasons.
The vernal equinox, the summer solstice, the autumnal equinox and the winter solstice are located in the middle of each season.
On the day of the spring equinox, the sun shines directly on the equator, and the day and night time around the earth is similar. Therefore, the ancient spring equinox is also called “day and night”, and the folks have the proverb of “spring equinox, day and night”.
After the vernal equinox, the wintering crops in most areas of spring enter the spring growth stage.
In Central China, there is a farmer who has “the spring equinox gets up and is worth a thousand dollars.”
The temperature in all parts of the province continues to rise, but it is generally not as fast as the rain to the spring equinox.
In the second half of March, the average temperature in the north is 13 ° C to 15 ° C, and the northern part is 15 ° C to 16 ° C.
Most of the plateau has been snow melting, and the average temperature in June is about 5 °C to 10 °C.
The temperature in the valleys of the Jinsha River and Anning River in the southwestern part of the province is the highest, with an average of 18 ° C to 20 ° C.
In addition to the marginal mountainous areas, the average daily temperature in the basin is steadily rising to above 12 °C for ten or eight years. It is conducive to sowing of rice, corn and other crops, and afforestation is also very suitable.
However, the basin before and after the vernal equinox often has a cold air intrusion, and the temperature drops significantly. The minimum temperature can be as low as 5 °C.
Sometimes there are small cold air coming one after another, forming a low temperature and rain that lasts for several days, which is not good for agricultural production.
According to this feature, the weather forecast should be fully utilized, and the cold-tailed warm head should be seized at the right time.
In order to facilitate farming, the western part of the world divided the year into a clothing season, and the second season was “from the spring equinox to the seven stars of Virgilier.”
The vernal equinox is the midpoint of the spring, and at the same time one year a year, “the spring equinox, the yin and yang are also half, so the night and night are cold and flat.”
On the vernal equinox, the sun is just above the equator, and at the same time, its own light is evenly distributed to the north and south of the earth.
People usually say: just as fair as the law.
Actually this is the ratio of the spring equinox or the autumn equinox. This is a metaphor that is not very appropriate (because the law is ultimately reflected by the judge).
Before and after the vernal equinox, if you take a little walk in the morning, notice that the sun is rising from the east.
After the vernal equinox, the northern people who were “unclear and unclear, and closed by the sky” clearly felt that the sun was getting closer.
