When is the first frost and what does it mean?

The first frost solar term means that the weather is getting colder and the first frost appears. It is the last solar term in autumn and also means the beginning of winter. Health care is particularly important in the first frost season. There is a folk proverb that "it is better to make up the first frost one year", which shows the influence of this solar term on us.

First, Frost's basic explanation

The first frost means that the weather is getting colder and first frost begins, which is the eighteenth of the 24 solar terms. The first frost is the last solar term in autumn when the sun is at 2 10 on the 23rd or 24th of October in the solar calendar. The first frost refers to the first frost. Twenty-four solar terms say: "In mid-September, the air is cool and condensed, and the dew is like frost." At this time, when the temperature drops below 0 degrees, the water vapor in the air condenses into white crystals on the ground, which is called frost. At this time, the first frost usually appears in the Yellow River valley in China, and most areas are busy planting crops such as wheat. Plants that are not hardy will stop growing and present a scene of late autumn, which is a good opportunity to enjoy the maple leaves. Yizhoushu Zhou said: "Autumn and March are empty: summer, autumn equinox, first frost." "Mandarin Zhou Yuzhong": "See the fire and cool breeze to stop the cold." "The History of the Three Kingdoms Wu" notes: "As the saying goes, after the first frost, the breeze comes first, and people should have a cold heart." Wei Wei's "Oriental" Chapter 15: "In the solar terms, there are several frosts here before the first frost."

Overview of first frost solar terms

First frost-it's getting colder and colder, and it's frosting. The first frost usually occurs on the 23rd or 24th of the Gregorian calendar 10 year 10. At this time, the first frost appeared in the Yellow River basin in China, and most areas were busy planting crops such as wheat.

In ancient China, the first frost was divided into three stages: "One stage was that the jackal sacrificed animals; Second, the vegetation is yellow; Three waiting insects are salty. " In this solar term, jackals will show their prey before eating; The leaves on the earth turned yellow and fell; The stinging insects are motionless in the cave and hang their heads into hibernation.

The first frost occurs when the sun reaches the longitude of 2 10 degrees every year around Gregorian calendar 10 year10 23rd. The first frost said that the weather was colder and the dew condensed into frost. "Twenty-four solar terms": "In mid-September, the essence is cold and condensed, and dew cream". At this time, frost has appeared in the Yellow River Basin of China, and a silver ice crystal shines in the fields thousands of miles away. At this time, the leaves turned yellow and fell. The ancient book "Twenty-four solar terms" says: "When the frost comes, the yin begins to coagulate." It can be seen that "first frost" means that the weather is getting colder and it begins to frost. Meteorologically, the first frost in autumn is generally called "first frost" or "first frost", and the last frost in spring is called "late frost" or "final frost". The interval from the last frost to the first frost is a frost-free period. Some people also call the first frost "Chrysanthemum Frost", because chrysanthemums are in full bloom at this time, and Su Shi, a great writer in the Northern Song Dynasty, said in a poem: "All trees are sweeping away pornography, and only Furong is alone."

Frost is formed by condensation of water vapor. How can water vapor condense into frost? Lv Benzhong, a poet in the Southern Song Dynasty, wrote in Luzi IV in the Southern Song Dynasty: "The moon invades the post, and the bridge spends the night frost." Lu You wrote in Frost Moon that "the withered grass is frosty and gray, and the cold window is full of new shadows." It shows that frost appears on a clear moonlit night in autumn. There are no clouds in the autumn night, and the ground is like a quilt, which radiates a lot. When the temperature suddenly drops below 0℃, the water vapor on the ground will condense on streams, bridges, leaves and soil, forming tiny ice needles, and some will become hexagonal frost flowers. Frost can only form on sunny days. People say that "the thick frost is fierce" is the reason.

The origin of the first frost solar terms

Every year around Gregorian calendar 10 year 10, when the sun reaches the longitude of 2 10 degrees, it is the first frost in the 24 solar terms. The first frost is the last solar term in autumn, which is the transition from autumn to winter. There is a lot of heat dissipation on the ground in autumn, and the temperature suddenly drops below 0 degrees. Water vapor in the air directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers, which are white and loose in structure.

"Twenty-four solar terms" said that the first frost: in mid-September, the gas was cold and condensed, and the dew became frost. At this time, frost has appeared in the Yellow River Basin of China, and a piece of silver ice crystals is shining in the fields thousands of miles away. At this time, the leaves turned yellow and fell. The ancient book "Twenty-four solar terms" said: "Qi stagnates at the beginning of frost, and Yin begins to coagulate". It can be seen that the "first frost" means that the weather is getting colder and the dew condenses into frost. In ancient China, the first frost was divided into three stages: first, the jackal sacrificed animals; Second, the vegetation is yellow; Three stings are salty. The jackal began to catch prey, sacrifice animals, and return books to heaven with animals, paving the way for sacrificing autumn gold; The leaves on the earth turned yellow and fell; The stinging insects are motionless in the cave and hang their heads into hibernation. "The first frost in the first frost" reflects the climate characteristics of the Yellow River Basin. As far as the annual frost days are concerned, there are frost and snow in some parts of the Qinghai-Tibet Plateau even in summer, and the annual frost days are over 200, which is the place with the largest number of frost days in China. The annual frost days in eastern Tibet, southern Qinghai, Qilian Mountains, western Sichuan Plateau, northwestern Yunnan, Tianshan Mountains, Altai Mountains, western mountainous areas of northern Xinjiang, northeast China and eastern Inner Mongolia all exceed 100 days, and the vast areas south of Huaihe River, Hanshui River and east of Dongpo of Qinghai-Tibet Plateau are all below 50 days, with only the annual frost days in the south of 25 north latitude, Sichuan Basin, south of Fuzhou and coastal areas of Guangdong and Guangxi being/kl.

"The first frost kills a hundred herbs", plants that have been hit by severe frost have no vitality at all. This is because the liquid in plants forms ice crystals due to frost, protein precipitates, and the water in cells extravasates, which makes the protoplasm seriously dehydrated and deteriorated. "The wind knife and frost force the sword", which shows the ruthlessness and cruelty of frost. In fact, frost and frost are inseparable, but it is "freezing" that harms crops, not "frost". Someone once tried to put two leaves of a plant in a box with the same low temperature, one of which was frosted and the other was not frosted. Results The leaves were seriously damaged in frost-free period, but there were only slight frost marks in frost period. This shows that frost can not only harm crops, on the contrary, when water vapor condenses, it can also release a lot of heat. 0 g of steam at 1℃ condenses into water, and the heat of vaporization released is 667 calories, which will turn heavy frost into light frost and light frost into dew to avoid frostbite.

climate change

The solar term of the first frost means that the weather is getting colder and first frost begins. To the south of latitude, the average temperature is around 16℃, and there are three solar terms before the first frost day. In the southern valley of South China, frost can only be seen in the dead of winter. Of course, even at the same latitude, the temperature and humidity of the air close to the stratum are different due to the difference of altitude and topography, and the first frost period and frost day are also different. [2] In the first first frost season, the cool autumn wind blew to Guangzhou, the flower city. The average temperature in northeast China, eastern Inner Mongolia and most parts of northwest China has been below 0℃.

"The first frost in the first frost" reflects the climate characteristics of the Yellow River Basin. As far as the annual frost days are concerned, there are frost and snow in some parts of the Qinghai-Tibet Plateau even in summer, and the annual frost days are over 200, which is the place with the largest number of frost days in China.

The first frost in autumn is called the first frost. The earlier the first frost, the greater the harm to crops. The first frost in all parts of China is gradually delayed from north to south and from mountainous areas to plains. Except for areas with frost all the year round, frost first appeared in the north of Daxing 'anling, usually at the end of August. The first frost in most parts of Northeast China, Inner Mongolia and Northern Xinjiang is mostly in September. 10 Frost has appeared in Shenyang, Chengde, Yulin, Qamdo and Lhasa. 165438+1Frost has been seen in Shandong Peninsula, Zhengzhou, Xi 'an and northwest Yunnan in early October; Frost did not appear in eastern China, Hanshui and Yunnan provinces until the beginning of 65438+February. When first frost went from Xiamen and Guangzhou to Baise and Simao, it was the beginning of October after 65438+ years.

Frost is the condensation of water vapor when the ground encounters cold weather, so it is not the frost in the first frost, but the phenomenon that the ground will produce the first frost when the weather is cold. From a scientific point of view, the saying that "dew becomes frost" is not accurate. The frozen dew formed by dew freezing is hard small ice beads. Frost refers to the phenomenon of crop freezing injury caused by the sudden drop of temperature, and its harmful temperature varies with crops, varieties and growth periods. To form frost, the temperature of the ground or ground objects must drop below 0℃, and the water vapor content in the air on the ground should reach a certain level. Therefore, there may not be frost in first frost, and there may not be frost in first frost. However, due to the low temperature during frost, if the temperature continues to drop, it will easily lead to frost.

"The first frost kills a hundred herbs", plants that have been hit by severe frost have no vitality at all. This is because the liquid in plants forms ice crystals due to frost, protein precipitates, and the water in cells extravasates, which makes the protoplasm seriously dehydrated and deteriorated. "Wind knives and frost force swords", which shows the ruthlessness and cruelty of frost. In fact, frost and frost are inseparable, but it is "freezing" that harms crops, not "frost". Someone once tried to put two leaves of a plant in a box with the same low temperature, one of which was frosted and the other was not frosted. Results The leaves were seriously damaged in frost-free period, but there were only slight frost marks in frost period. This shows that frost can not only harm crops, on the contrary, when water vapor condenses, it can also release a lot of heat. 0 g of steam at 1℃ condenses into water, and the heat of vaporization released is 667 calories, which will turn heavy frost into light frost and light frost into dew to avoid frostbite.

It is better to say "frost kills a hundred herbs" than "the first frost kills a hundred herbs". Frost is the expression of cold weather, and freezing is the enemy that kills crops. Because there is frost when it is frozen (sometimes no frost is called black frost), autumn frost and spring frost are collectively called frost.

Pay attention to solar terms

Crop change

In the first frost, autumn harvest has been completed in most parts of the north. Even cold-resistant onions can't grow any longer, because "the first frost can't support onions, and the longer they grow, the more empty they are." In the south, it is the peak season of "Sanqiu". Only single-season hybrid rice and late rice are harvested, and early-season wheat and early-season rape are planted. Picking cotton, pulling cotton stalks, ploughing and soil preparation. "The straw is pulled all over the floor, and there will be fewer insect pests and diseases in the future." Take back the straw and stubble in time after harvest, because there are many wintering eggs and germs hidden there. The Chinese cabbage in North China is about to be harvested, so it is necessary to strengthen the later management. In the first frost season, most parts of China have entered the dry season, so we should attach great importance to forest protection and fire prevention. The first frost is also a good time to raise sheep in Huanghuai basin. As the agricultural proverb goes, "the first frost breeds clear milk, and the grass grows." Ewes are generally in estrus in autumn and winter, and the duration of mating with rams is generally about 30 hours. Like mating with the Southern White Dew, lambs are born with warm weather, fresh grass, good nutrition and plenty of milk, which can milk lambs well. Anti-freezing measures:

(1) Plant early in time and stagger the frost in late autumn;

(2) selecting early-maturing and high-yielding varieties;

(3) water, because dry soil dissipates heat faster than wet soil;

(4) Smoking can form heat preservation clouds in a small area, thus reducing freezing injury;

⑤ hoeing, "the hoe has fire", can increase the ground temperature;

⑥ Apply sodium humate or phosphate fertilizer to make crops mature in advance. Experiments show that it can ripen Chinese yam, corn and millet for 5-7 days in advance.

The most fundamental thing is afforestation, which can adjust the temperature and completely change the environment.

Medicinal diet and dietotherapy

The first frost, health care is particularly important. There is a folk proverb that "it is better to make up the first frost once a year", which shows the influence of this solar term on us.

The first frost solar term is the peak period of recurrence of chronic gastritis and gastroduodenal ulcer. The elderly are also very prone to "old cold legs" (knee osteoarthritis), and chronic bronchitis is also prone to recurrence or aggravation. At this time, you should eat more pears, apples, ginkgo, onions and mustard (potherb mustard). Chestnut has the effects of nourishing stomach and strengthening spleen, tonifying kidney and strengthening tendons, promoting blood circulation and stopping bleeding, relieving cough and resolving phlegm, and it is a good tonic at this time. Frost is spread all over vegetation and rocks, commonly known as frosting. Frosted vegetables such as spinach and wax gourd are particularly delicious, and frosted fruits such as grapes are particularly sweet. The ancients generally ate mutton and rabbit meat in autumn. On the day of the first frost, the people of Fujian and Taiwan have to make up for it. There is a proverb in southern Fujian that "it is better to make up the first frost than to make up for one year".

Some places want to eat red persimmons, thinking that they can keep out the cold and replenish their bones and muscles. Quanzhou old man said: eating persimmon diced in the first frost will not cause runny nose. Some places say that you should eat a shuttlecock on the first frost day, otherwise your lips will crack all winter. In other places, you must eat some beef on this day. Shandong agricultural proverbs: summer sorghum, white deer valley, first frost radish.

At the time of the first frost, he belonged to the earth in the five elements. According to the viewpoint of TCM health preservation, as far as the relationship between four seasons and five supplements (spring supplement, summer supplement, long summer supplement, autumn supplement and winter supplement) is concerned, at this time, he belongs to the soil in long summer, and should take the principle of light supplement to replenish blood, replenish qi and nourish stomach. Dietary supplements should be differentiated according to the taste and sexual orientation of food.

Dietary health care focuses on regulating yin and yang according to the "taste of food", nourishing the five internal organs and preventing diseases. Therefore, in traditional health care, food is also divided into different types according to its "sexual taste".

As the last solar term in autumn, the weather is getting colder, autumn dryness is obvious, and dryness is easy to hurt Tianjin. The first frost should pay attention to keep warm first, and then prevent autumn dryness, and the amount of exercise can be increased appropriately. In terms of diet care, it is appropriate to make up at this time. Pay attention to strengthening spleen and nourishing stomach, nourishing liver and kidney, and eat more foods that strengthen spleen, nourish yin and moisten dryness. Corn, radish, chestnut, autumn pear, lily, honey, yam, milk cabbage, beef, chicken and loach are all good.
