Is beginning of spring the beginning of spring? There are many ways to divide the four seasons. Beginning of spring is a very common solar term. In the sense of solar terms, beginning of spring is beginning of spring, but if not in terms of climate, do you know that beginning of spring is beginning of spring?
Is beginning of spring the beginning of spring? 1 Is beginning of spring the beginning of spring? It means the beginning of spring.
Beginning of spring is the first of the 24 solar terms, which means the beginning of a year and marks the beginning of a new cycle. Among the 24 solar terms, beginning of spring is described as "beginning of spring, the solar term in the first month; Stand still, build the beginning; The five elements of qi continue here; And the qi of Chunmu begins, so it stands; Long summer, autumn and winter are the same. " In rural areas, there is a saying that "spring beats six or nine heads", but in "Counting Nine Songs" and "Looking at willows along the river in May and June", the arrival of beginning of spring means the beginning of "spring life", and in rural areas, "spring life" is implied as "gestation".
In rural areas, people used to regard "beginning of spring" as the beginning of spring. However, China has a vast territory and a large span from north to south. During the beginning of spring solar term, 93% of the country is still in winter, so the arrival of spring should be decided by climatology. That is to say, the average temperature in a certain area is above 10℃ for five consecutive days, even if it is lower than 10℃ for the next few days, it cannot exceed five consecutive days, otherwise it cannot be regarded as beginning of spring. The temperature difference between the north and the south of China is quite large, and the most suitable days for beginning of spring are from Guangxi to Jiangxi. For the northeast, the real spring should be around Grain Rain.
Is spring the beginning of spring? No.
China/kloc-the custom of 0/8 years old. The north is called receiving gods. China, Fujian, Taiwan Province and other places are the most popular. This day is the first day of the first month of the summer calendar, but the time is different every year. According to the emperor's calendar, people in China usually break dead branches before dawn. Spring breeze awakens everything, full of vitality, the human body corresponds to nature, the whole body metabolism is more and more vigorous, and the function is more and more active. Therefore, spring health should also adapt to this feature. The theory of traditional Chinese medicine is known as "spring is the season, and spring gas can pass through the liver", which guides us to adapt to the climate and adjust food, clothing, housing and transportation in spring.
Is beginning of spring the beginning of spring? As far as solar terms are concerned, beginning of spring is the beginning of spring, but as far as climate is concerned, beginning of spring is not.
Ancient and modern sayings are different:
One way of saying this is to start with "beginning of spring". The reason is that "beginning of spring" is the first of the 24 solar terms. Beginning of spring is usually on February 4th to 5th in the solar calendar, just within ten days before and after the Spring Festival. However, just taking "beginning of spring" as beginning of spring is not in line with the actual weather conditions.
The second is the traditional saying. The spring of China lunar calendar is correction month, February and March. The first month is called "early spring", February is called "Meng Chun" and March is called "mid-spring". This statement is more realistic.
The third statement is the regulation of modern meteorology: the first day when the daily average temperature is stable above 10℃ for five consecutive days is divided into spring.
China has a vast territory, and it is more scientific to determine the time of entering spring with the average temperature as the standard.
The ancient book "Qunfangpu" explains this: "Li, the sword is 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℃.
Climatic characteristics of beginning of spring
Beginning of spring solar terms
In the early spring, in the tropic of cancer and its vicinity, the weather is warm, everything begins to grow, temperature, sunshine, rainfall and so on. Often at the turning point of the year, it tends to rise or increase, and it can be clearly felt that the days are getting longer and the sun is getting warmer. Since the beginning of the beginning of spring solar term, westerly jet, the southern branch of East Asia, began to weaken, but the strength and position of westerly jet, the northern branch of East Asia, remained basically unchanged. The Mongolian cold high and Aleutian low are still relatively strong, but in the intermittent period affected by strong cold air, the frequency of southerly winds increases, accompanied by obvious warming process.
China has a vast territory, mainly located in the middle and low latitudes. Low latitude refers to the spatial range between 30 degrees north and south latitude on the earth's surface, that is, the area between 30 degrees north latitude and 30 degrees south latitude, including tropical and subtropical hot zones, which is the area where global solar radiation and heat are concentrated. In low latitudes, it is rainy, stormy, sunny and humid. With the change of seasons, rainfall, illumination and storms change obviously. Mid-latitude is the latitude zone between 30 and 60 degrees north latitude. The air masses prevailing in high and low latitudes overlap with each other, with frequent cyclone activities and large temperature difference, and the temperature changes obviously when the seasons change. The climate varies greatly at different latitudes.
"beginning of spring" is a seasonal solar term, which marks the beginning of spring and represents warmth and growth. The geographical dividing line between winter and spring is on the line from Guilin, Guangxi to Ganzhou, Jiangxi. When spring begins to celebrate festivals, the area south of this line has the smell of spring. Beginning of spring is a solar term with a slight turning point, which is not obvious in the whole country.
"Li Si" marks the rotation of four seasons, and reflects the changing laws of phenology and climate such as spring, long summer, autumn harvest and winter storage, as well as the changing laws of sunshine, rainfall and temperature. After beginning of spring, the spirit of the sun began to rise, the sunshine increased, and the days became longer, which meant that the winter when everything was hidden ended and the growing season began. Everything gradually recovered and the weather began to get warmer.
Only Lingnan in the south really enters the spring during the festival, and the breath of early spring has come to my face; In the north, everything is still bleak, and it is still snowing in some places. Beginning of spring, more can only be said to be a prelude to spring, has not yet entered the spring. China has a vast territory, complex geographical conditions and great differences in climate, so the specific climate significance of "Li" does not apply to all parts of the country. Although seasonal changes can reflect the climate (temperature) characteristics of the four seasons in the middle and lower reaches of the Yellow River, the specific phenological and climatic significance of "Li" is not significant. "Li" is just a reference in many areas. In China's climatology, beginning of spring is usually defined as a day when the daily average temperature rises steadily above 10℃ every five days.
Is beginning of spring the beginning of spring? Spring begins in early spring.
Standing is the beginning, and beginning of spring is beginning of spring. 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℃.
Spring Equinox
Divide means divide equally. The vernal equinox means that day and night are equally divided. After the vernal equinox, the overwintering crops in most parts of southern China entered the spring growth stage. In central China, there is an agricultural proverb, "Wheat starts at the vernal equinox, and every moment is worth a thousand dollars". The temperature in most parts of the south continues to rise, but generally it doesn't rain as fast as the vernal equinox.
In late March, the average temperature in northern South China is mostly 13℃ to 15℃, and in southern South China it is mostly 15℃ to 16℃. Most of the plateau has been melted by snow, and the ten-day average temperature is about 5℃ to 10℃. Most areas in South China, such as river valleys, have the highest temperature, with an average of 18℃ to 20℃. In the south, except for the marginal mountainous areas, the average daily temperature rose steadily to above 12℃ in 1978, 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, there is often a strong cold air intrusion in South China, and the temperature drops obviously, 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.

Speaking of beginning of spring, people obviously feel that the days are getting longer and the sun is getting warmer. Temperature, sunshine and rainfall are often at the turning point of the year and tend to rise or increase. The growth of crops in early spring is accelerated, and the water consumption for bolting rape and jointing wheat is increased. Irrigation and topdressing should be done in time to promote growth. Agricultural proverbs remind people that "it rains in early spring, get up early and go to bed late", and Da Chun has begun to prepare for agriculture. Although it is spring, most parts of South China are still very cold. The snow in spring came too late, so it is flying through the Woods.
These climatic characteristics should be taken into account when arranging agricultural production. Where is the information that people often look for in spring? The buds protruding from the wicker are "softer than gold and softer than silk". The eager grass in the soil is waiting for "they grow taller in the spring breeze". In order to win a new harvest, people who work hard in the fields are creating real spring with their hands.
The poem says: "The east wind brings rain to drive the west wind, and the earth is sunny and warm. Su Meng wakes up everything, and farmers seek agriculture at the beginning. " Beginning of spring, Heshui Zuo
