What does long summer mean? What is a long summer? What are the characteristics of long summer?

Long summer is the seventh solar term in the twenty-four solar terms of the lunar calendar and the first solar term in summer, which indicates the official start of the summer season. When the sun reaches 45 degrees of the yellow meridian, it is the solar term of long summer. The bucket refers to the southeast, and the dimension is long in summer. Everything has grown to this day, hence the name Long Summer.

Twenty-four solar terms: Long Summer and April Festival. Make a word to understand spring. Summer, holidays. At this time, everything is fake and big. "Astronomically, Chang Xia said that saying goodbye to spring is the beginning of summer. When the temperature rises obviously, the summer heat comes, thunderstorms increase and crops enter the peak season, people are used to taking long summer as an important solar term.

Long summer is a solar term established at the end of the Warring States Period (239 BC), which indicates the change of four seasons and the beginning of summer in four seasons.

In fact, according to the standard of climatology, the daily average temperature rises to above 22℃ steadily, starting from summer. Before and after the "Long Summer", only the area south of Fuzhou-Nanling Line in China is really "the trees are dark in midsummer, and the balcony reflects the pond", while some areas in the northeast and northwest have just entered the spring, and the average temperature in most parts of the country is around 18 ~ 20℃, which is ". In May, Sophora japonica blooms in many places. In the long summer, everything is thriving.

Solar term temperature

According to the standard of climatology, summer begins when the average temperature of that day rises above 22℃. Before and after the "Long Summer", only the area south of Fuzhou-Nanling Line really entered the summer in China, while some areas in the northeast and northwest just entered the spring at this time, and the average temperature in most parts of the country was around 18-20℃.

In the long summer, the temperature in the north and south of China is very different, and fluctuates frequently in the same area. The temperature in the rest of South China is around 20℃. The low-altitude valley felt hot in summer as early as mid-April, and the temperature in long summer was above 24℃. Therefore, it is also a period of frequent crop diseases and insect pests, and it is a period when people are prone to catch cold. As Heshui Zuo said, "The south is like the summer in the north and the spring in the north. The trees are green and beautiful. When you are sick, the insects disperse the medicine, and the medicine is hot and cold. "

Rainwater characteristics

After the long summer, Jiangnan officially entered the rainy season, and the rainfall and rainy days increased significantly. Continuous rainy days not only caused wet damage to crops. It will also cause the prevalence of many diseases. The heading and flowering period of wheat is the most susceptible period to scab. If warm but rainy weather is expected in the future, close attention should be paid to spraying chemicals from the early flowering period to the full flowering period. Cotton in southern China often causes outbreaks of anthracnose, damping-off and other diseases under the weather conditions of continuous rain or sudden warming and cold, resulting in large-scale dead seedlings and lack of seedlings. Necessary measures to increase temperature and reduce humidity should be taken in time, combined with chemical control to protect seedlings and strive for strong seedlings. "There are many kinds of seedlings in the long summer, and more millet is harvested in Man Cang", and it is the red season of early rice transplanting in the north and south of the Yangtze River before and after the long summer. Full-moon seedlings can be planted, but full-moon grass can't be planted. At this time, the temperature is still low. Immediately after planting seedlings, we should strengthen management, topdressing early, ploughing early, controlling pests early and promoting development early. Pay close attention to tail sweeping when sowing mid-season rice. At this time, the spring shoots of tea trees develop fastest. If we ignore them, tea leaves will get old. As the saying goes, "Grain Rain picks less, but doesn't pick it in the long summer", so we should concentrate our efforts and harvest it by surprise in batches.

Before and after the long summer, the temperature in North China and Northwest China rose rapidly, but the precipitation was still not much. In addition, the wind is strong and evaporation is strong in spring. Atmospheric dryness and soil drought often seriously affect the normal growth of crops. Especially, the dry hot wind before and after wheat filling and milk ripening is an important disastrous weather that leads to yield reduction, and timely irrigation is the key measure for drought resistance and disaster prevention. "hoes are everywhere for three days in the long summer", when weeds grow rapidly. "Don't mow the grass for one day, and don't mow it for three days." Intertillage weeding can not only weed, resist drought and prevent waterlogging, but also increase the ground temperature and accelerate the decomposition of soil nutrients, which is of great significance to promote the robust growth of crops such as cotton, corn, sorghum and peanuts at seedling stage.

After the long summer, it is the key period for planting early rice in a large area, and the arrival and amount of rain during this period are closely related to the future harvest. The farmer's proverb says well: "If it doesn't last long in summer, the plow will hang high." "There is no rain in the long summer, and there is no rice in the head." There is also a folk custom of weighing and fearing the heat in summer. Jiangxi also has the custom of drinking tea in long summer, saying that if you don't drink long summer tea, you will feel uncomfortable all summer.

Summer welcoming ceremony

Summer welcoming ceremony

The word "summer" in "long summer" means "big", which means that the plants sown in spring have grown upright. In ancient times, people attached great importance to the customs and habits of long summer.

On the long summer day, the ancient emperor would lead officials to the southern suburbs of Beijing to welcome the summer and hold a ceremony to welcome the summer. The monarch and his subjects all wear scarlet ceremonial costumes and jade ornaments, and even horses and car flags should be scarlet to express their prayers and good wishes for a bumper harvest. In the imperial court, "open the ice in summer and give it to the civil and military ministers." Ice was stored last winter and given to officials by the emperor.

In Jiangsu and Zhejiang, people are sad and cherish spring because of the bright spring, so they prepare wine and vegetables for fun, as if they were giving people away, and call it Hunchun. In Fu, Cui Jian said: "Welcome to the summer is the first, and the spring is the last." Wu Outing's poem "Long Summer" also said: "There is no way to go in spring, and the cherry blossoms return in spring." ? [2]?

In the folk, people drink cold drinks to cool off in summer. In summer, there is a custom of boiling tender broad beans in Jiangnan water town. In some places, there is also the custom of calling people in summer.

Taste new activities

Later generations have a festival in summer, such as tasting new things. For example, there is a saying in Suzhou that "three creations are seen in the long summer", and the three creations are cherries, plums and wheat, which are used for ancestor worship. In Changshu, tasting new foods is more abundant, and there is a saying of "nine meats and thirteen vegetables". Nine meats are crucian carp, salted eggs, snails and quenching (that is, cooked with small fire; A cooking method comprises processing with various spices to make chicken, salted fresh, marinated shrimp and cherry meat; Thirteen elements include cherry, plum, wheat silkworm (new wheat is kneaded into thin strips and cooked), bamboo shoot, broad bean, spear tip, pea, cucumber, lettuce, grass head, radish, rose and pine flower. In Nantong, we eat boiled chicken and duck eggs.

Egg beating game

At noon that day, every household cooked the eggs (the eggs were cooked in shells and could not be damaged), soaked them in cold water for a few minutes, then put on woven net bags and hung them around the children's necks. Children will play egg-beating games in groups of three or five. An egg has two heads, the pointed one is the head and the round one is the tail. When you beat eggs, the head of the egg hits the head of the egg and the tail of the egg hits the tail of the egg. Fight one by one, the loser gives up, and finally the high and low are separated. The winner of the egg head is the first, and the egg is king; The winner of the egg is the second place, and the egg is called Xiao Wang or Er Wang. As the saying goes, "an egg hangs on the chest in the long summer, and the child has no summer sickness." Summer sickness is a common anorexia, which can cause abdominal distension, fatigue and emaciation in summer, especially for children. Lunch is glutinous rice mixed with peas. There must be boiled eggs, whole bamboo shoots, peas with shells and other special dishes on the dining table. Eat double eggs and bamboo shoots in pairs, no matter how many peas. According to folklore, eating eggs in the long summer depends on the heart. Because eggs are shaped like a heart, people think that eating eggs can keep the spirit from losing money. It will be a hot summer after a long summer. In order not to lose weight in hot summer, Chang Xia should take supplements. With a thriving life, people's legs are as strong as bamboo shoots, and they can travel long distances by their legs. Peas with shells are shaped like eyes. Eye diseases were common in ancient times. In order to eliminate eye diseases, people pray that their eyes will be as clear as fresh peas for one year by eating peas.

There is a custom of weighing people at lunch in the long summer. People hang a big wooden scale at the entrance of the village or platform, and a stool is hung on the scale hook. Everyone takes turns to sit on the stool and weigh people. When weighing flowers, the caller said auspicious words. The old man will say, "weigh 87 and live to 91." The weighing girl said, "105 Jin, someone is looking for you outside." Unwilling, unwilling, unwilling, the son of the champion has a fate. " The weighbridge said, "When the weighbridge is over ten or twenty-three, the young official will grow up. Seven county officials should not be guilty, and three public officials and nine ministers should climb. " Weighing flowers can only be typed in (that is, from decimal to large number), but not outside. Legend has it that Zhuge Liang is related to the stories of Meng Huo and Liu Adou. It is said that after Meng Huo was surrendered to Shu by Zhuge Liang, he took orders from Zhuge Liang. On his deathbed, Zhuge Liang entrusted Meng Huo to visit the master of Shu once a year. Zhuge Liang instructed that day, which happened to be the long summer of this year. Meng Huo immediately went to worship Adou. Since then, every summer, Meng Huo has promised to visit Shu. A few years later, Sima Yan, Emperor Wu of Jin Dynasty, destroyed Shu and took Adou away. Meng Huo did not forget the entrustment of the Prime Minister. Every year, Chang Xia led troops to Luoyang to visit Dou E, and every time he went, he weighed Dou E to verify whether Dou E was abused by Emperor Wu of Jin Dynasty. He threatened to fight Kim if he mistreated Dou. In order to accommodate Meng Huo, every year in the long summer, Emperor Wu of Jin used glutinous rice and peas to make lunch for Adou. Dou saw that peas were glutinous and fragrant, and he ate them twice. Meng Huo weighed people in the city, weighing several kilograms more each time than the previous year. Although Adou has no skill, he has Meng Huo's reputation as a man in the long summer, and Emperor Wu of Jin did not dare to bully him, so he lived a quiet and happy life and lived a long and happy life. Although this legend is different from historical facts, what people want is a peaceful world of "peace and happiness, long life". People who weigh in the long summer will bring good luck to Adou, and people also pray to God to bring them good luck.
