Frostfall: Autumn Finale, the Wisdom of the Ancients' Guide to Farming.
It's time for the annual "frost fall" solar term, which is the eighteenth of the twenty-four solar terms and the end of autumn. After the "frost falls", the earth will enter an icy winter. At this time, people can clearly feel the sudden drop in temperature, the temperature difference between day and night increases, and the cold air moves south. However, there is an old rural saying, "Frost does not see frost, and there will be famine in the coming year" has aroused people's curiosityWhat makes sense?
The crystallization of the wisdom of the ancients: the 24 solar terms and agricultural production.
The 24 solar terms are the crystallization of ancient wisdom, especially in agrarian societies, where climate change has an important impact on agricultural production. To a large extent, this system was used by the ancients to guide agricultural production. There is an old saying in the countryside: "If the frost falls, there will be a famine in the coming year". How exactly is this sentence understood?
From white dew to frost: the process of a gradual cooler climate.
The solar term "frost falls" mainly refers to the appearance of frost. The two solar terms that precede frost are "white dew" and "cold dew", which refer to the condensation of water vapor into dew and the cooling of dew, respectively. From white dew to frost, it means that the water vapor gradually becomes colder and the climate gradually cools. It's a step-by-step process.
Types of frosts: initial frost, final frost and frost period.
"Frost" is a natural phenomenon, and the first frost that appears in autumn is called the first frost or early frost, and the last frost that appears in spring and winter is called the final or late frost. The period from the first frost to the final frost is called the "frost period", while beyond that there is the "frost-free period". Plants are very sensitive to climate sensing, so the timing of frost has an important impact on crop growth.
Frost falls without frost": the temperature is warmer, and the southward movement of cold air is delayed.
The first half of the old saying, "frost does not see frost" refers to the fact that the temperature is relatively warm, and the cold air is not enough to form frost, and it also represents the delay of the southward movement of cold air. The onset of the first frost is also delayed, which naturally delays the arrival of the late frost.
The effects of the first frost on autumn crops: from wheat to snow.
The first frosts occur in autumn and mainly affect autumn crops, such as wheat. The ancients also said: "Ruixue Trillion Year", if the winter is not cold enough, the phenomenon of warm winter is not enough to freeze the pests in the field, which may lead to insect infestations in the next year. The melting of the snow provides water and nutrients for the next year's crops. However, warm winters can also trigger "inverted spring cold", which became a climate disaster in the eyes of ancient farmers.
The impact of "frost without frost" on spring crops: overlapping critical periods of agricultural production.
In addition to affecting autumn crops, "frost without frost" also means that late frosts are delayed, and this is a critical period for spring crop sowing to sprout rapidly. The delay of late frost can affect the survival rate of spring crops and even freeze to death in severe cases. Spring was the main planting stage for farmers in ancient times, so the saying "if there is no frost when frost falls, there will be famine in the coming year" came into being.
The meteorological concept of the ancients: plants adapt to the laws of the climate.
The ancients believed that plants have adapted to a regular climate, the four seasons are distinct, and the order of hot and cold is a good meteorological phenomenon. There is a saying as evidence: "lukewarm, not old". However, with the development of the times, the progress of scientific civilization, people's in-depth research on agriculture, the vigorous development of agricultural science and technology, and the gradual weakening of dependence on climate.
Conclusion: The development of agricultural science and technology and the changes of meteorology.
In modern society, people's understanding of meteorology is no longer as harsh as that of the ancients. The development of agricultural science and technology has provided farmers with more tools and means to cope with climate change. Although the old saying "frost does not fall without frost, there will be famine in the coming year" is not absolute, it still reflects the sensitivity and dependence of ancient farmers on the weather. In the new era, we will be able to make better use of science and technology to combat climate change and ensure the smooth running of agricultural production.
Welcome to the exchange: the fusion of ancient wisdom and modern technology.
This article tries to read the meteorological code behind the old saying in the ancient countryside, "frost does not see frost, and there will be famine in the coming year". The blend of ancient wisdom and modern technology has given us a deeper understanding of meteorological changes. Welcome to leave a message and work together to ** the significance and application of ancient wisdom in modern society.
This article profoundly interprets the rich meaning of the ancient rural saying "frost does not see frost, and there will be famine in the coming year", and at the same time puts it in the context of the 24 solar terms and ancient agricultural production. The author's skillful use of scientific knowledge and the wonderful blend of ancient wisdom and modern technology give readers a deeper understanding of the importance of meteorological changes to agriculture.
First of all, the paper clarifies the status of the frost solar term, highlights its uniqueness among the 24 solar terms, and emphasizes the sensitivity of ancient agrarian societies to climate change. Through the interpretation of the ancient proverb "frost does not see frost, there will be famine in the coming year", readers have a deeper understanding of the observation and understanding of meteorology by the ancients.
Secondly, the author introduced the concept of frost period in detail, and pointed out the direct impact of the first frost and the final frost on crop growth. The "snow trillion year" mentioned in the article, as well as the interpretation of warm winters and cold springs, further demonstrate the direct impact of climate on agricultural output. This interpretation of the relationship between meteorology and agriculture reveals to the reader a deep understanding of the natural environment of ancient farmers.
Subsequently, the article cleverly uses the development of modern technology and agricultural technology to show that farmers now have more tools and means to deal with climate change. This contrast makes readers feel the convenience brought by scientific and technological progress to agricultural production, and also makes people more confident in the future development of agriculture.
Finally, at the end of the article, readers are welcome to leave a message and jointly ** the application of ancient wisdom in modern society. This interactive design enhances the reader's sense of engagement and stimulates deep thinking about agriculture, meteorology, ancient wisdom and modern technology. Overall, the article is lively and interesting, in-depth and provides readers with a rewarding journey of knowledge.
