Expand knowledge about spring;

Overview:

Spring, also known as spring, is the first season of the year, covering the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. This is the season when everything comes back to life. The Gregorian calendar in the northern hemisphere is March-May, and in the southern hemisphere (such as Australia) it is September-165438+ 10. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable.

Shu Ya:

In spring and March, it is said that the world is born, everything is glorious, lying late and getting up early, walking (walking) in the court, and walking slowly (meaning unrestrained) to do life. Living without killing, giving without taking, rewarding without punishment, this is the response of spring and the way to keep fit. Otherwise, it will hurt the liver, it will be cold in summer and there will be few elders.

Chunyang: It is named after the warm and beautiful sunshine in spring. Chen Ziang's poem "If you don't return in the daytime, it's dusk in spring". It's a poem about Chunyang.

Yangchun: the laudatory name of spring. Among the poems of Li Bai, a poet in the Tang Dynasty, there is a poem "Spring beckons me to smoke".

Fangchun: It is named after the sprouting of vegetation in spring, the rebirth of fragrant grass, and the blooming of flowers in full of green. Lu Ji's poem "Strong heart in autumn, beautiful clothes in spring". Write the characteristics of Fangchun into the landscape.

Stupidity: In ancient times, "spring" and "stupidity" agreed to speak at the same time. When spring comes, insects will move, and both shapes and sounds will know.

Youth: named after the green vegetation in spring. Du Fu's poem: "In that green spring day, I sang loudly, I drank heavily, and that green spring day took me home".

Sunny sun: I won this honor because of the sunny spring. In Hua Guangsheng's Collection of Folk Songs in Qing Dynasty, there is a saying: "Snow is shining in spring": "On a sunny day, the wind is swaying and the willows are swaying, blending".

Sanchun: Because spring includes January, February and March, it is collectively called "Sanchun". Meng Jiao's poem: "Only an inch of grass grows, and three wisps of spring scenery are a little sentimental".

Jiuchun: folk custom, ten days is a spring, and spring has ninety days, so it is also called Jiuchun. The poet Ruan Ji has a poem: "Strange to say, if it is in September, the rock will break like autumn frost."

Hiking: also called spring outing, spring outing, etc. China's outing custom has a long history. Legend was first formed in the pre-Qin period, and some people say it began in the Wei and Jin Dynasties. According to the Book of Jin, every spring, people go to the suburbs to enjoy the scenery together, especially in the Tang and Song Dynasties. Du Fu, a poet in the Tang Dynasty, once recorded the grand occasion of the royal spring outing. "On March 3rd, the world is new, and many beautiful women are walking along the Chang 'an seaside." For thousands of years, outing has gradually become a ceremony, as if only by doing this ceremony can we really have spring. "I don't play in spring, but I am afraid I am an idiot." Bai Juyi's poem "Spring Tour" is a portrayal of this mentality.

In addition, there are more than twenty appellations such as "Yang Festival", "Zhao Festival", "Yun Festival", "Shu Festival" and "Ling Lun".

Solar terms:

Beginning of 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. Birds and flowers; Spring is growth, cultivation and sowing. In climatology, spring refers to the period when the average temperature is between 10℃ and 22℃.

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.

It's raining.

It began to rain, and it gradually increased. The meaning of rain solar term is that rainfall begins and gradually increases. In the Yellow River valley, the birthplace of the 24 solar terms, the weather was cold before it rained. But I saw the snow falling and the nasty rain falling. After the rain, the temperature can generally rise above 0℃, with less snow and more rain. However, in the warm southern region, even in the dead of winter, rainfall is not uncommon. The average temperature in most parts of southern China in this period is above 10℃, peaches and plums are in bud, and cherries are in full bloom. It is indeed a climatic spring. In addition to a few years, the frost period has come to an end. It is timely to graft fruit trees and plant trees. After a dry winter, there are many droughts in spring all year round in South China, especially in the western part of South China, where "spring rain is as expensive as oil". In agriculture, attention should be paid to moisture conservation and timely irrigation to meet the water supply at the jointing and booting stage of wheat and the critical period of bolting and flowering of rape. The mountainous area of the northwest plateau is still in the dry season, with low temperature and high wind speed, which is prone to forest fires. In addition, the attack of cold wave will cause strong cooling and snowstorm, which will do great harm to the old, the weak and the young. These should pay special attention to prevention.

(3) Fear

Sting means hiding. Sting refers to the sudden movement of spring thunder, which awakens the hibernating animals in the soil. By the time of the earthquake, most parts of China had entered the busy season of spring ploughing. Really: the season waits for no one, and every moment is worth a thousand dollars. In most areas, the average temperature of scary solar terms is generally 12℃ to 14℃, which is more than 3℃ higher than rainy solar terms, and it is the solar term with the fastest annual warming. The sunshine time has also increased significantly. However, due to the alternation of cold and warm air, the weather is unstable and the temperature fluctuates greatly. In the Yangtze River valley in the southeast of South China, the temperature in the warning period is stable above 65438 02℃ in most years, which is beneficial to the sowing of rice and corn. The average daily temperature in other areas is lower than 12℃ for more than three consecutive days, so it is not allowed to sow blindly early. Although the temperature rises rapidly, the increase of rainfall is limited. The total rainfall in central and northwest South China is only about 10 mm, and spring drought often begins after winter drought all the year round. At this time, the booting stage of wheat and flowering stage of rape are in a period of high water demand and are sensitive to water demand. Spring drought often becomes an important factor affecting the output of Koharu. Afforestation should also consider this climate feature, plant logistics and water, and strive to improve the survival rate of saplings.

(4) vernal 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.

(5) Qingming

Every year on April 4th or 5th of the Gregorian calendar, folk customs sweep graves on this day. Qingming is a solar term representing phenology, which means sunny weather and lush vegetation. Tomb-Sweeping Day has folk customs such as climbing mountains, eating cold food and sweeping graves.

As the saying goes, "Qingming breaks snow, Grain Rain breaks frost." When the weather is clear, the climate in South China is warm and the spring is strong. However, before and after Tomb-Sweeping Day, cold air still invaded from time to time, even making the average daily temperature lower than 12℃ for more than three consecutive days, resulting in rotten seedlings of middle rice and dead seedlings of early rice. Therefore, it is necessary to avoid warm tail and cold head when sowing and transplanting rice. In the northwest plateau, livestock are weak under the influence of severe winter and insufficient forage, so it is necessary to guard against the harm of strong cooling weather after spring to old, weak and young livestock.

"There are many rains during the Qingming Festival" is a portrayal of the spring rain in the south of the Yangtze River by Du Mu, a famous poet in the Tang Dynasty. But in some areas, this is not the case. Especially in the western part of South China, it is often in the spring drought period, and the rainfall in early April is generally only 10 to 20 mm, which is less than half of that in the south of the Yangtze River. Although there are many spring rains in eastern South China, the rainfall in early April is generally only 20 to 40 mm, so natural precipitation is not enough for agricultural production, so it must be replenished by storing water years ago. In addition, May-June is the month with the most hail in a year, so the prevention of hail disaster should be strengthened.

(6) Grain Rain

Rain has bred hundreds of valleys. With sufficient and timely rainfall, cereal crops can thrive in Grain Rain season in southern China. "Young flowers fall, cuckoos cry at night, peonies bloom and cherries are ripe. The natural scenery tells people that it is late spring. At this time, the temperature in the south rises rapidly. Generally, in late April, except for parts of northern and western South China, the average temperature has reached 20℃ to 22℃, which is more than 2℃ higher than that in mid-April. In the eastern part of South China, there is often a high temperature above 30 for a day or two, which makes people feel very hot. Low-altitude valley areas are used to enter summer. The climate characteristics of high temperature in south China in spring are beneficial to the early cropping cultivation measures in Da Chun. The suitable planting temperature of Polygonum cuspidatum is 65438 08℃ to 22℃, which can be satisfied at this time. The experience in the old arid areas in southern China has proved that planting Osmunda japonica early in Grain Rain can seal vine leaves before summer drought, enhance drought resistance and achieve high and stable yield.
