Extended data

The origin of solar terms:

Twenty-four solar terms are a supplementary calendar formulated by the ancients to guide farming. They are called "solar calendar" because they sum up the changing rules of seasons, climate and phenology in a year through long-term observation of the sun's annual movement.

Since the Xia Dynasty, the working people in our country have been engaged in production activities according to the 24 solar terms, so it is also called the "summer calendar". 1972, Shennong Gregorian clay pot was unearthed at Tumen site in Yichuan, Henan Province. The whole calendar is a double day, like a big circle with five eyes. According to the research of historian Mr. Wang Dayou, this picture represents the 24 solar terms.

Today, the decorative Chinese watch column in front of the building is an instrument for observing the sky and measuring the earth in the era of Emperor Yan. People take a tree as a pole, measure the orientation, time and solar terms with the length of the sun shadow, and observe the period of the stars. Early ancestors also used this "sundial" to divide the 24 solar terms, and thus realized the cosmic concept of "the sky is round and the place is round". In this way, solar terms have been invented for at least 6000 years.

In BC 104, the calendar compiled by Luo officially designated the 24 solar terms as the calendar, and made clear the astronomical position of the 24 solar terms. In the long-term labor practice, the ancestors summed up a set of laws governing the operation of nature through careful observation of nature-that is, a season can be subdivided into six solar terms, and four seasons are twenty-four solar terms.

What is the last solar term of the vernal equinox? What is the vernal equinox?

One, equal day and night, equal season

The "vernal equinox" has two meanings: one is that "day and night are equal". On the vernal equinox, the sun shines directly on the equator, which is almost equal to the length of day and night in the world, that is, the time of day and night is equal, which is 12 hour. At this time, after half a year of darkness, the North Pole saw the sunshine for the first time on this day, and the corresponding South Pole will also bid farewell to the sunshine on this day. After the vernal equinox, the position of direct sunlight moves northward, and the daytime time in the northern hemisphere becomes longer and the nighttime time becomes shorter, but the difference is that the daytime becomes shorter and the nighttime becomes longer in the southern hemisphere. The second refers to "season sharing". If the period from the beginning of spring to the long summer is regarded as spring, then the vernal equinox is the midpoint of spring, which just divides spring equally. It is exactly ninety days from beginning of spring to Changchun, and the vernal equinox is divided into two, hence the name vernal equinox.

Second, spring is dominant.

As far as the spring referred to in the 24 solar terms is concerned, there are often obvious weather changes around the vernal equinox. At this stage, the weather is changeable, and the alternation of cold and warm is obvious. Although cold air still comes and goes frequently, it has retreated to the second line, and the warm and humid airflow from the ocean has begun to occupy a dominant position in China. The middle and lower reaches of the Yangtze River and Huanghuai area have also entered the spring defined by climatology, and the average temperature is basically stable above 10℃. In those areas, there are already peanut trees, grass grows and warblers fly. As the saying goes, "flowers are getting more attractive, but shallow grass has no horseshoe." However, the vast area north of the Yellow River is still in the transition stage from winter to spring. It is sunny and windy, warm and cold at first, and sometimes there is a situation of "giving charcoal in the snow".

At this time, the disastrous weather that needs to be vigilant is the drought and sandstorm in the north and the cold damage in the south.

Third, planting early rice in spring.

At the vernal equinox, winter crops in most parts of China entered the spring growth stage, and winter wheat began to turn green and jointing. The agricultural proverb "Wheat starts at the vernal equinox, and a moment is worth a thousand dollars" indicates that winter wheat has entered the field management stage. Southern early rice began to transplant seedlings in the south. "It rains in the spring equinox, and everyone is busy. First plant wheat, then transplant rice." Hard-working people can be seen everywhere in the fields This is the time for people to sow hope.

The vernal equinox is also the best time to plant trees and arrange flowers. Arbor Day in China is scheduled for March 12. There is a proverb that says, "When the season is at the vernal equinox, we should plant trees quickly. If the spring equinox is not planted well, it will be difficult to survive if it is planted again. " It can be seen that solar terms are important for planting trees.

The vernal equinox, one of the 24 solar terms, is the fourth solar term in spring. The solar term of the vernal equinox begins on March 20th or 2 1 day of the Gregorian calendar every year, and the sun reaches 0 degrees of the yellow meridian (vernal equinox) and ends on April 4th (or 5th). On the vernal equinox, the sun shines directly on the equator, and the length of day and night is almost equal, which is exactly half of the ninetieth day of spring, so it is called "vernal equinox". The vernal equinox is the fourth of the 24 solar terms. In ancient times, it was also called "Japan-China", "Day and Night Minute" and "Mid-Spring Moon", and it was celebrated around March 21(20th to 22nd) every year.

According to the "Twenty-four solar terms": "In mid-February, it is divided into half, which is half of ninety days, so it is called minutes." Another "Spring and Autumn Annals" said: "The vernal equinox, Yin and Yang are also half-phase, so it is cold and summer day and night." There is a "Li Mingshi Yi" cloud: "The dividing line, the point where Huangchi intersects, the sun is here, and the day and night are equally divided." Therefore, the significance of the vernal equinox, first, refers to the equal division of day and night, each of which is 12 hours; Second, in ancient times, it was spring from beginning of spring to long summer, and the vernal equinox happened to be in the three months of spring, and spring was equally divided.

In ancient China, the vernal equinox was divided into three periods: "First, waiting for the arrival of birds; Second, wait for Lei Nai to make a sound; Third, wait for electricity. " In other words, after the vernal equinox, swallows will fly from the south, and when it rains, the sky will thunder and lightning.

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 have entered the spring growth stage. There is an agricultural proverb: "When wheat starts at the vernal equinox, it is always worth a thousand dollars." At this time, the temperature in all parts of our province continued to rise.

What is the temperature after the vernal equinox?

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.

What is the temperature after the vernal 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.

What fruit does the vernal equinox eat?

pineapple

In spring, many fresh pineapples are on the market. Pineapple contains almost all vitamins and 16 natural minerals needed by human body, which can effectively help digestion and absorption.

When eating pineapple, trim off the skin and thorns, cut the pulp into pieces, soak in light salt water or sugar water to leach out glycosides, and then eat. After pineapple is soaked in salt water, it can effectively destroy the internal allergic structure of "pineapple prion", thus losing the ability to make people allergic and the toxicity to some constitutions.

orange

Among many kinds of fruits, acidic fruits contain more vitamin C. Today's nutrition has unanimously praised vitamin C as one of the antioxidants. The weather is dry in spring, and eating oranges in spring can effectively supplement water and vitamin C and delay aging. Oranges also have the effects of promoting fluid production to quench thirst, soothing the liver and regulating qi, promoting lactation, promoting digestion and appetizing, and have a good nourishing effect.

Oranges are delicious, but don't eat too much. Brush your teeth and rinse your mouth in time after eating oranges to avoid harm to your mouth and teeth. Don't soak the orange peel in water to drink, because the orange peel now generally contains preservatives, which is difficult to clean with water.
