What month is the spring stipulated in China?

China stipulates that three months from beginning of spring to long summer is spring.

Spring, also known as spring, is the first of the four seasons, which refers to 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. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days.

Beginning of spring is beginning of spring, beginning of spring is beginning of spring. Since the Qin Dynasty, beginning of spring has been the beginning of spring in China. As one of the 24 solar terms, beginning of spring, like Changxia, beginning of autumn and beginning of winter, reflects the changes of the four seasons throughout the year, which also means the beginning of a new cycle and a new year.

Six solar terms in spring

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 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℃.

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.

The poem says: "The east wind brings rain to drive the west wind, and the earth is sunny and warm. Everything wakes up in the dream, and the farmer looks for farming at the beginning of the year. -beginning of spring, Heshui Zuo

Rain Water

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.

The poem says, "It is wet in the south and cold in the north, warm first and then cold, rainy and windy.". Returning to the green for a thousand miles overnight, Wanshan is silent. " -Rain in Heshui Zuo.

Awakening of Insects

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.

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.

The poem says: "A thunderbolt woke up the snake insect, and several showers turned purple. In 1999, the wind in the south of the Yangtze River warmed up and the green fields began to plow in spring. " -Heshui Zuo's Surprise

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℃.

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.

The poem says: "Wind and thunder send warmth into mid-spring, and peaches and willows wear white clothes. The equatorial golden sun shines directly on the surface of the earth and is divided equally between day and night. " -Heshui Zuo's vernal equinox

Qingming Festival

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.

"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.

The poem says: "It's sunny every year, and the swallow swallows the willow and loses its soul. Silent Qingshan people rush, and money, paper and candles are presented to the tomb of the first Lord. " -Qingming in Heshui Zuo

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.

The poem says: "frequent rain, frost death, willow green tea fragrance." The cuckoo is singing in spring, and there are many things. " -Grain Rain, Heshui Zuo
