Introduction to the vernal equinox solar terms

The vernal equinox, also known as the old "Japan" and "night" and "month" of air, after a year in March 21st (20 ~ 22) section, according to the lunar calendar date is not fixed, when the sun reaches the longitude 0 °.According to the pulled seventy-two hou set solution ":" in February, points half also, when half of the ninety - day, so call."The other sections about chun-qiu theory, Yin and Yang from handover said: "the spring equinox, the Yin and Yang in half, also reason both night and day and year."Have, Ming calendar, one said: "points, make intersection point, the sun line at this point, is the equinox."So, the meaning of the spring equinox, one is a day to day and night to split, each for 12 hours;The second is the ancient spring to the beginning of spring, the spring equinox as three months, to split the spring.The vernal equinox is divided into three syndrome in ancient China, "a bird to hou yuan;2 HouLei is voice;Three hou electricity."Is said after the spring equinox, the swallow was coming from the south,It rainsThe sky was thunder and lightning.The vernal equinox recorded in Chinese ancient calendar for: "three days before the vernal equinox, the sun into the equator"

The vernal equinox origin

The vernal equinox from every year on March 20, 21 (or) to April 4 (or 5) end.The vernal equinox, the Gregorian calendar every year on March 20 or 21, the sun reaches 0 degrees longitude, vernal equinox.The day the average length of day and night, just as the spring ninety, half of so called "vernal equinox".The vernal equinox this day direct sunlight on the equator, day and night almost equal, then position of direct sunlight gradually moved to start the nights are short.The vernal equinox is a more important solar term, it not only has the meaning of in astronomy: north and south hemispheres equinox;On the climate, there are obvious characteristics of the spring equinox season, except for the qinghai-tibet plateau in China north, northeast, northwest and north China region outside into the beautiful spring, in the vast land, willow green, apr, jointing stage of wheat, rape flowers.

"Pulled seventy-two hou set solution" : "(a summer) in February, points half also, when half of the ninety - day, so the call.In the autumn of synonymy.Han dong "sections about chun-qiu theory, Yin and Yang in and out of context" : "as for the month of spring, in the sun in the east, Yin in illicit affair, of the vernal equinox.Half is the vernal equinox, the Yin and Yang, reason both night and day and year."The ancient Yellow River basin corresponding phenological phenomenon as "fenice to, ray is vocal, electricity" (see "farming through travelling).When the winter into spring crop growth stage in most regions.Central China farmer's saying: "vernal equinox wheat and moment values do gold."The vernal equinox is also a traditional festival.In the zhou dynasty, the spring equinox has anniversary ceremony."Rites" : "death in it."Kong Yingda hydrophobic: "vernal equinox is also."The common past dynasties.Qing Pan Rong pursuit "at the age of emperor jing JiSheng" : "equinox memorial song, autumnal equinox, offering month is the ceremony of the sergeants may not be good at si."The word before and after the spring equinox in the qing dynasty, the palace temple is secretary to sacrifice, to family showed also so the ancestral hall.In Liang Zong deloitte was alarmed at the age of jingchu "load:" vernal equinox day, the people and types of ring of fire on the grass in the house.With birds such as Ukraine, first chicken tolls, \ 'frame to vanquish \', people wait the bird into the field, thought."Shandong paper studied in Ming dynasty. The planting trees, spring liquor, wine and cool."Wenshui county" : "vernal equinox day, wine mixed with cool, substitute stealthily."

Throttle characteristics

The vernal equinox this day direct sunlight on the equator, day and night almost equal, then position of direct sunlight gradually moved to start the nights are short.

The farther from the equator places on earth, the smaller the Angle of the sun at noon, get less sunlight.General in the northern hemisphere, spring, is three, four, five three months in the southern hemisphere for the autumn.

Equinox solar terms, east Asian trough significantly weakened, westerlies groove ridge activity markedly increased, Mongolia to the northeast region of low pressure development activities and turning, low-voltage mobile guide cold air southward, the more high winds and flying sand weather in northern China.When the long-wave trough eastward, form cold warm air mass convergence effect, there will be a continuous and pollen rainy weather.

The vernal equinox season, in addition to the year is winter alpine region and north latitude 45 ° north of the region, across China are stable shengda the average daily temperature 0 ℃ above, the cold has gone, the rise of temperature quickly, especially in north China and huanghuai plains, almost daily average temperature and rainy in the south of the Yangtze river along the river at the same time the shengda above 10 ℃ and into a bright spring.The vast land, AnLiu qingqing, apr, jointing stage of wheat, rape flowers, peach li bai chun huang.But is is a scene in the south China region.Say from weather patterns and jiangnan precipitation increased rapidly, entering the spring flood period in spring;In "the spring rain your such as oil" in the northeast, north and northwest area still little precipitation, resist the threat of drought is one of the major problems of agricultural production.

"Vernal equinox wheat and moment value daughter", little rain in spring in the north region to clutch spring, water the good filling water, good jointing fertilizer, pay attention to defense late frost cold;The south still need to continue to do a good job of the drainage prevent stains.Jiangnan rice seedlings and jianghuai region early film work has started on rice seedlings, early spring weather changes in temperature changes frequently, seed sprouting, attention should be paid to the cold air comes at the end of the cold air fine sowing.People experience, said: "cold end warm head, seedling under not sorrow."According to the weather, for sowing after 3-5 a sunny day, to keep a full stand.Fresh tea have begun to sprout, should be timely and quick fertilizer topdressing, prevention and control of plant diseases and insect pests, strive for high quality tea.

"February insects awaken the vernal equinox, fertilization deep cultivated land to plant trees."The vernal equinox is also a great time to afforestation, poems have "midnight meal cattle call woman, planting trees is the vernal equinox Ming dynasty" in the sentence.In the hot, the busy farming season to continue to use our hands to afforest the broken pieces back together, to beautify our environment.

The vernal equinox is one of the solar terms reflect the change of the four seasons.The ancient Chinese habits in spring, summer, the beginning of the beginning of autumn and the beginning of winter said the four seasons.The vernal equinox, summer solstice, autumnal equinox, winter solstice, is in the middle of the season.The vernal equinox day, the sun was shining on the equator, day and night time is equal to all over the earth, so the ancient vernal equinox is also called "points" day and night, folk have "vernal equinox, equinox" saying.

After the spring equinox, large parts of southern China winter into spring crop growth stage.Central China has "vernal equinox wheat and moment value daughter" the farmer's proverb.Across much of the south the temperature continues to rebound, but generally not as good as the rain during this period the vernal equinox to rise quickly.In late march average temperatures in northern south China more for 13 ℃ to 15 ℃, southern south China more than 16 ℃ to 15 ℃ to.Most parts of the plateau has the snow melt away, ten-day average temperature 5 ℃ to 10 ℃.Most region of southern China, such as river valley is the highest temperature, the average has reached 18 ℃ and 20 ℃ or so.Southern besides edge mountains, seven, eight years an average of 10 day average temperature stability up to 12 ℃ above, be helpful for sowing rice, corn and other crops, afforestation is very appropriate also.But, before and after the spring equinox in south China, often have a strong cold air invasion, the temperature dropped significantly, the lowest temperature can be as low as 5 ℃ below.Sometimes a little cold air followed, form the last several days low temperature rain, adverse to the agricultural production.According to this characteristic, should make full use of the weather forecast, catch cold end warm head timely planting.

The vernal equinox this day direct sunlight on the equator, day and night almost equal, the difference is in the northern hemisphere is spring, autumn in the southern hemisphere is, then position of direct sunlight gradually moved to the northern hemisphere of solar radiation, the weather is getting warm, the day grew at the same time, drawing in the night.Equinox solar terms, form cold warm air mass convergence effect, rain also want more.

The common saying say: "vernal equinox wheat and water to follow.After a spring rain, a warm, spring rain busy farming.Spring busy season is about to begin, ChunGuan, spring, spring is about to enter a busy period.After the spring equinox, winter crops into the growth stage, must strengthen field management.Due to the rise of temperature quickly, the water demand is opposite bigger, to strengthen water keep moisture farmer friends.

The vernal equinox phenomenon

Astronomical phenomena

In the time period is to point to the sun is highest in the longitude position between 0 ° and 15 ° degrees, is about March 20 solstice between April 5.But in practice usually refers to the sun really located at longitude on the day of 0 ° : on March 20, or on March 21.

The phenomenon of the earth

The vernal equinox, the sun point-blank point on the equator, and then the sun point continued north, so the vernal equinox, also known as points.

When the spring equinox, in theory, global length of day and night (see twilight).After the vernal equinox, around the northern hemisphere day gradually grow shorter night, all over the southern hemisphere night grew day grow shorter.

When the vernal equinox, no surfaces at polar night phenomenon around the world.After the spring equinox, starting near the arctic surfaces, the range is too large;Surfaces at the end near Antarctica and polar night, range gradually.

Phenological phenomenon

Fenice to: fenice, yan also, high induced yue: "vernal equinox, autumnal equinox is also."

Ray is thin for the thunder voice: Yin and Yang, so far, four Yang sheng, the children of judah have Yin yan, phase thin voice is enough;Is, "rhyme will" yue: "also out of the difficult."The appearance yue: "hair, out of judah."

Electricity: electricity, sunshine also;Four long Yang excessiveness and value of gas drainage and sometimes light life.Therefore, "through the solution of" yue: "every sound, Yang also;Light, also Yang also."Yi" yue: "thunder and lightning and chapter."The ram biography and yue: "electric LeiGuang."Is also, yue: "LeiYang, electric shade."No.Cover of summer without ray, electricity has also, so great.

Geographical conditions

On March 21, is the spring equinox in the 24 solar terms."Vernal equinox, the Yin and Yang in half.So both day and night and through flat."A "points" word out the boundaries of day and night, year.When the sun is 0 degrees longitude, the position of the sun above the equator.Lunar recorded in the book "bucket nonyl for the spring equinox, about Sunday, north and south hemispheres divide day and night, and when the spring and a half, so called the vernal equinox."The vernal equinox day is in the spring of ninety days, day and night is equal in both hemispheres.From this day, the sun position gradually move to the north, north and south hemisphere and the changes of day length, nights are short in the northern hemisphere and the southern hemisphere, on the other hand.The spring comes, the rain increased significantly, China's average ground temperature has stabilized by 10 degrees, this is defined by the spring temperature on climatology.After the vernal equinox solar terms, mild climate, abundant rain, sunny, winter into spring crop growth stages in many parts of the country, is also the early rice seeding time at this time.

The vernal equinox keeping in good health

The vernal equinox solar terms:

Every year on March 19 ~ 22, the day is the spring equinox in the 24 solar terms."Vernal equinox, the Yin and Yang in half.So both day and night and through flat."A "points" word out the boundaries of day and night, year.When the sun is 0 degrees longitude, the position of the sun above the equator.Lunar recorded in the book "bucket nonyl for the spring equinox, about Sunday, north and south hemispheres divide day and night, and when the spring and a half, so called the vernal equinox."

The vernal equinox day is in the spring of ninety days, day and night is equal in both hemispheres.From this day, the sun position gradually move to the north, north and south hemisphere and the changes of day length, nights are short in the northern hemisphere and the southern hemisphere, on the other hand.The spring comes, the rain increased significantly, the average ground temperature has stabilized by 10 degrees in our country, this is defined by the spring temperature on climatology.After the vernal equinox solar terms, mild climate, abundant rain, sunny, winter into spring crop growth stage in most regions of our country, is also at this time of early rice seeding time.Around the farmer's proverb had a different version of the vernal equinox, shandong has a proverb "vernal equinox day plant trees, is fine, everything is not a";Hubei has "the spring rain every busy, kind of melon beans before planting".Guangdong has a proverb "vernal equinox in the former, m fights the money".

Ouyang xiu of the vernal equinox had a brilliant description: "south garden spring half for an outing, the wind and the smell of each other, greengage as bean willow as eyebrow, day long butterflies fly."North or south, is a good time of the spring equinox solar terms in China's Taiwan province is orchids bloom.

Due to the spring equinox solar terms to split the night and day, year, people in the health care keeping in good health should be paid attention to keep the balance of Yin and Yang of human body.Stalin tells us: "the possibility of relatively static object, the possibility of temporary balance, is the essential condition of matter differentiation, and hence the essential condition of life".We in order to have this kind of "balance" temporarily "fundamental condition" of life, to keep the body balance of Yin and Yang became an important rule in the past, this principle, no matter in the aspects of spirit, diet, daily life and cultivate on or in the use of self care and drugs is very important.We how to use a balance of Yin and Yang in the health law, coordination of the body function, achieve the balance of inside and outside the body, make human body the organic whole always maintain a state of relative calm, balance is the basis of health care."Plain ask to want to really big theory" : "we would like to examine and adjust the Yin and Yang is to flat for".Is said that the body should according to the different periods of Yin and Yang, the "internal movement" is the zang-fu organs, qi and blood, essence of physical movement, and the "outward movement" harmony, namely, mental, physical and sports to keep the balance of the relationship between the supply and marketing.Avoid the occurrence of improper movement and destroy the balance of human body internal and external environment, accelerate the body damage to certain organs and physiological function disorder, resulting in the occurrence of diseases, shorten people's life.Modern medical research proof: a man's life in the process of activities, because of the mismatch metabolism, which can lead to the occurrence of certain elements in the body of imbalance, excessive, some elements of the accumulation content of some elements deficiency causes premature aging and disease.While some non-infectious diseases are related to the human element balance disorders.Such as the harm to human health in the world's largest production of cardiovascular disease and cancer, and is closely related to the disorder of material exchange balance inside body, investigate its reason, notting have is not imbalance of Yin and Yang.Balanced health theory research thinks, different age groups in life, according to the different physiological characteristics, adjust the structure of the corresponding diet, supplement necessary trace elements, maintain the balance of various elements in the body, will be good for our human health.

"Element asked, bone theoretical" : "the Yin and Yang, deficiencies are fill, more than the purge".Traditional health food and Chinese medicine treatment can be summarized as two aspects of tonify deficiency and diarrhea.Such as tomifying qi, blood, Yin, Yang, oneself fill, to fill the empty;Nourish, heat, water, purging, remove cold, and the wind, dry wet can be regarded as diarrhea.Medicine practice has proved that no matter or have diarrhoea, should adhere to the adjustment of Yin and Yang, with flat for the principle of scientifically diet care, can effectively control many non-infectious diseases.From the standThe Spring FestivalGas toThe qingming festivalGas is grass grow the bud, before and after the blood also, in the period of strong hormone level is in a relative peak, at this point is used common non-infectious disease with high blood pressure, menstrual disorders, hemorrhoids, and allergic disease, etc.In the throttle diet nursing, should choose according to their own actual situation to maintain the body function to coordinate a balanced diet, taboo partial hot, slant cold, partial litres, partial diet myths, such as in cooking fish, shrimp, crab is cold sex food, its principle will with onion, ginger, wine, vinegar class warm spices, to prevent the cold slants cool dishes, food after damage spleen and stomach and cause no sigh of rou GUI;And as in edible leeks, garlic, papaya and other Yang dishes often with egg ziyin quality, in order to achieve the purpose of the Yin and Yang are complementary.In thinking to stay relaxed and happy, optimistic state of mind.In daily life to insist on proper exercise, regular sleep, quantitative, purposefully for nursing, can achieve the best effect of preserve one's health.

The vernal equinox diet

Equinox solar terms when blood also, in the period of strong hormone level is in a relative peak, at this point is used non-infectious disease with high blood pressure, menstrual disorders, hemorrhoids, and allergic disease, etc.The general principles to dietary taboos big hot, severe cold diet, a balanced fever.This period is not drinking soup too fatty.

The vernal equinox witticism

Each year at the vernal equinox day, the world will have to millions of people are doing "the egg" test.This is referred to as "China custom", how to become a "game of the world", it is difficult to textual research.But the style is simple and full of fun: select a smooth and trim, and just give birth to the fresh of the four or five dayseggs, softly on the table to it.Although there are many losers, but many winners, too.The vernal equinox is the best time of the egg game, therefore has the "vernal equinox to, egg, qiao".Not scenery of our stand.

The vernal equinox this day why eggs easily stand up?Although there are many claims, but the science is really a lot.First of all, the spring equinox, day and night is the north and south hemispheres as long days, was 66.5 degrees tilt of the earth's axis and the earth's orbit around the sun plane is in a state of relative balance, is conducive to the egg.Secondly, the spring in the middle of the spring, not cold not hot, red flower, the heart happy, the thought is agile, action, seem quite easy to the egg.And, more importantly, the surface of the egg rugged, there are many bumps "hill"."Mountain" high around 0.03 mm, the distance between the peaks between 0.5 ~ 0.8 mm.According to three points form a triangle and determine a plane, as long as find three "hill" and composed of the three "the hills" triangle, and make the line of centre of gravity of eggs through the triangle, then the egg will stand.In addition, it is best to choose 4 ~ 5 days after birth eggs, this is because the egg lecithin with relaxation, egg yolks, egg weight drops, erected in favour of eggs.

Erect eggs not only has a lot of scientific reason, but also contains a lot of rich profound philosophy.The famous Italian navigator Christopher Columbus sailed across the vast Atlantic ocean, discovered the new world, some of his findings, even think of it as a "by accident".At a victory celebration meeting, Columbus proposed Sir Lady miss try at a dinner party, can the egg upright on the table, the result does not have a success.Columbus said, now watch the performance.He put upon eggs, egg shell is broken, the egg would be erected.Then he said, "this is what I found, it is easy, but, why are you not?

Eggs well-balanced smooth curves is that it is difficult to stand, also is the charm of it.European Renaissance painter leonardo Da Vinci, famous ever forget all about eating and sleeping more than two years, practiced every day egg curve, the as he later successfully shaping Mona Lisa smile has laid a solid foundation.Our country folk call face "face", and using the egg as the face of standards, fully illustrates the high level of our people aesthetic appreciation level and aesthetic attribute of the egg.But, for a long time, people always can't find the egg-shaped curve mathematical expression, even mathematicians only with straightedge and compass to approximate curve to make eggs.It is no wonder that painter of the tens of thousands of eggs round also said that no two are the same.Until modern times, mathematicians mathematical equations to find the following egg curve: x ^ 2 / y ^ a ^ 2 + 2 / + b (ky) ^ 2 = 1, the | | k > 1, finally solved the egg curve tracing this confused generations problem.Today, the modelling of egg-shaped cars, airship, bridge, tunnel, stadium, concert hall and other buildings, can be seen all over the world, they are perfectly realize the science and culture, science and art, the combination of science and aesthetics.

The vernal equinox customs

The vast land, AnLiu qingqing, apr, jointing stage of wheat, rape flowers, peach li bai chun huang.Today the vernal equinox, the vernal equinox day what custom?

The egg

Equinox solar terms, east Asian trough significantly weakened, westerlies groove ridge activity markedly increased, Mongolia to the northeast region of low pressure development activities and turning, low-voltage mobile guide cold air southward, the more high winds and flying sand weather in northern China.When the long-wave trough eastward, form cold warm air mass convergence effect, there will be a continuous and pollen rainy weather.

The vernal equinox season, in addition to the year is winter alpine region and north latitude 45 ° north of the region, across China are stable shengda the average daily temperature 0 ℃ above, the cold has gone, the rise of temperature quickly, especially in north China and huanghuai plains, almost daily average temperature and rainy in the south of the Yangtze river along the river at the same time the shengda above 10 ℃ and into a bright spring.The vast land, AnLiu qingqing, apr, jointing stage of wheat, rape flowers, peach li bai chun huang.But is is a scene in the south China region.Say from weather patterns and jiangnan precipitation increased rapidly, entering the spring flood period in spring;In "the spring rain your such as oil" in the northeast, north and northwest area still little precipitation, resist the threat of drought is one of the major problems of agricultural production.

"Vernal equinox wheat and moment value daughter", little rain in spring in the north region to clutch spring, water the good filling water, good jointing fertilizer, pay attention to defense late frost cold;The south still need to continue to do a good job of the drainage prevent stains.Jiangnan rice seedlings and jianghuai region early film work has started on rice seedlings, early spring weather changes in temperature changes frequently, seed sprouting, attention should be paid to the cold air comes at the end of the cold air fine sowing.People experience, said: "cold end warm head, seedling under not sorrow."According to the weather, for sowing after 3-5 a sunny day, to keep a full stand.Fresh tea have begun to sprout, should be timely and quick fertilizer topdressing, prevention and control of plant diseases and insect pests, strive for high quality tea.

"February insects awaken the vernal equinox, fertilization deep cultivated land to plant trees."The vernal equinox is also a great time to afforestation, poems have "midnight meal cattle call woman, planting trees is the vernal equinox Ming dynasty" in the sentence.In the hot, the busy farming season to continue to use our hands to afforest the broken pieces back together, to beautify our environment.

The vernal equinox is one of the solar terms reflect the change of the four seasons.The ancient Chinese habits in spring, summer, the beginning of the beginning of autumn and the beginning of winter said the four seasons.The vernal equinox, summer solstice, autumnal equinox, winter solstice, is in the middle of the season.The vernal equinox day, the sun was shining on the equator, day and night time is equal to all over the earth, so the ancient vernal equinox is also called "points" day and night, folk have "vernal equinox, equinox" saying.

After the spring equinox, large parts of southern China winter into spring crop growth stage.Central China has "vernal equinox wheat and moment value daughter" the farmer's proverb.Across much of the south the temperature continues to rebound, but generally not as good as the rain during this period the vernal equinox to rise quickly.In late march average temperatures in northern south China more for 13 ℃ to 15 ℃, southern south China more than 16 ℃ to 15 ℃ to.Most parts of the plateau has the snow melt away, ten-day average temperature 5 ℃ to 10 ℃.Most region of southern China, such as river valley is the highest temperature, the average has reached 18 ℃ and 20 ℃ or so.Southern besides edge mountains, seven, eight years an average of 10 day average temperature stability up to 12 ℃ above, be helpful for sowing rice, corn and other crops, afforestation is very appropriate also.But, before and after the spring equinox in south China, often have a strong cold air invasion, the temperature dropped significantly, the lowest temperature can be as low as 5 ℃ below.Sometimes a little cold air followed, form the last several days low temperature rain, adverse to the agricultural production.According to this characteristic, should make full use of the weather forecast, catch cold end warm head timely planting.

The vernal equinox this day direct sunlight on the equator, day and night almost equal, the difference is in the northern hemisphere is spring, autumn in the southern hemisphere is, then position of direct sunlight gradually moved to the northern hemisphere of solar radiation, the weather is getting warm, the day grew at the same time, drawing in the night.Equinox solar terms, form cold warm air mass convergence effect, rain also want more.

The common saying say: "vernal equinox wheat and water to follow.After a spring rain, a warm, spring rain busy farming.Spring busy season is about to begin, ChunGuan, spring, spring is about to enter a busy period.After the spring equinox, winter crops into the growth stage, must strengthen field management.Due to the rise of temperature quickly, the water demand is opposite bigger, to strengthen water keep moisture farmer friends.
