Introduction: "The early cold dew freezes the cow, and the late cold dew is warm and dry", tomorrow's cold dew, is the cold dew early or late this year?
"The cold dew cleans the autumn sky, and the distant mountains are watching." Before we knew it, we had come to the cold dew, and tomorrow is October 8th, which is also the first day to enter the cold dew. Cold dew is the 17th of the 24 solar terms this year, as soon as the cold dew arrives, it means that the weather is colder, and it is also the time to plant rape and broad beans, if it is late, the yield will be reduced.
The cold dew is the season of late autumn and the beginning of the month of the Ganzhi calendar. The temperature drops during the cold dew season, and the dew is colder than the white dew solar term, and the dew at this time is about to condense into frost, so it is called "cold dew".
The ancients observed the celestial phenomena and found that there are three obvious characteristics of the cold dew solar term, which is also called "cold dew three waits", namely: one waiting for the guests of the wild goose; Second, the finch enters the water as a clam; Sanhou chrysanthemum has yellow flowers.
Waiting for the wild goose guests: In the first 5 days of cold dew, the geese line up and fly south.
Second, the finch enters the water for the clam: to the 6-10 days of the cold dew, in the late autumn season, the weather is cold and cool, the birds are gone, the ancients who live in the coastal area found that a lot of clams suddenly appeared on the seaside, and both the color and the texture are particularly similar to the birds, so they think that the clams are the birds change.
Sanhou chrysanthemum has yellow flower: in the 11-15 days of cold dew, chrysanthemums also bloom.
We can see from the three waits of the cold dew that the chrysanthemums have bloomed at this time, so in this season, people have the custom of drinking chrysanthemum tea, in addition, the cold dew is also the time to eat sesame seeds, the old people often say: "sesame mung bean cake, eat not long bag", indicating that eating sesame seeds at this time is conducive to physical health. At this time, the crabs are very fat, and people have tasted autumn crabs and drank autumn tea.
Let's see from these customs of cold dew, cold dew is a solar term that pays attention to diet and health, after all, winter is approaching, and it is more important to maintain a good body.
The cold dew is a busy time in the three autumns, at this time busy with autumn plowing and autumn planting, so the change of celestial phenomena is very important, the ancients observed the weather, found that in the cold dew solar term, the most afraid of three kinds of weather phenomena, if it appears, it may not be conducive to agriculture, such as reduced yield, in ancient times, grain yield reduction is a serious thing, may lead to famine. As the old saying goes, "There are three images of cold dew, and graves are raised everywhere", which is the case, so what exactly does it mean?
The first elephant: windy weather. During the cold season, the weather is already cold, and if there is a strong wind, the weather will be even colder, which is a threat to the crops that have not yet been harvested, such as causing lodging conditions, or blowing off the grain that has been produced, affecting the crop harvest. From the perspective of life, windy weather can affect people's health.
The second image: continuous rainy days. Cold dew and rainy weather are also unfavorable. It will make the originally cold weather even colder, which may cause frost damage to crops, and also allow crops to breed diseases and pests, thus affecting the growth of crops.
The third elephant: the great cooling. At this time, it is the rice heading and flowering period or grain filling in South China, if the weather is too cold, the late rice will appear empty shells and turtle grains due to low temperature, and the yield of late rice will be greatly reduced.
The ancestors found that the weather during the cold and dew seasons would affect the weather conditions that followed, such as winter. As the old saying goes: "The cold dew freezes the cow to death in the morning, and the cold dew is warm and dry in the evening", the cold dew tomorrow, is the cold dew early or late this year? Let's take a look at what the agricultural proverb says.
The cattle are frozen to death in the morning cold dew, and the cold dew is warm and dry in the evening
The meaning of this agricultural proverb is: if it is a year of early cold and dew, according to the experience of the ancestors, the next weather will be colder, especially in winter, which is a cold winter, and "frozen cow" is an exaggerated statement, used to describe the coldness of winter; On the contrary, if it is the case of late cold dew, according to the experience of the ancestors, the next weather will be warmer, and the winter is a warm winter.
So, is this year "early cold dew" or "late cold dew"?
Generally speaking, if the lunar time of the cold dew festival is before the first day of the ninth month, then it is considered to be "early cold dew"; On the contrary, if it is after the first day of September, it is considered to be "evening cold dew".
This year's cold dew arrives on October 8, the sixth day of the ninth lunar month, which is later than the first day of the ninth lunar month, which belongs to the situation of "late cold dew". "Warm dew in the evening", which means that this winter will be a warm winter.
There are many similar agricultural proverbs among the people, such as "the cold dew in the morning is so cold that it is crying, and the cold dew is warm in the evening", "before the cold dew on the first day of the new year, the snow is big and there is no road; After the cold dew on the first day of the new year, the clothes do not know the care" and so on. That's the case.
Early cold dew often means that the winter may be colder and snowy; The late cold dew may indicate a relatively warm winter, with less rain and snow. During the cold season, it is normal for the temperature to drop gradually. If the temperature drops rapidly after the cold dew and remains low, it may mean that it is an "early cold dew" year; Conversely, if the temperature drops slowly or fluctuates greatly, it may be a "late dew" year.
What is the impact of the late cold dew on agriculture?
The late cold dew indicates that the winter is a warm winter, which indicates that the warm winter will shorten the growth cycle of some crops, and the crops will not have sufficient dormancy and nutrient reserves during the overwintering period, which will affect the normal growth and development of spring. In addition, warm winters will also make crops enter the growth period in advance, such as too many rape branches, too strong wheat tillering, etc., resulting in weak plants, easy lodging, small ears, small pods, and incomplete grains, which ultimately affect yield and quality.
In the warm winter year, the crop growth is advanced, the cold resistance will be reduced, once there is a cold situation, the crops will be frost damage, there will be dry yellow leaves, wilting and dry, flower buds fall off and even frostbite and freeze to death, affecting the yield and quality.
If the cold dew rains every day, there is a lot of rain in February of the first month
This agricultural proverb means that if it rains on the day of the cold dew, then according to the experience of our ancestors, the rain will be more abundant in the first month of the following year and February.
New Year and February are the key periods for spring crop growth, and it is better to have sufficient rain to help the crops regreen, joint, and bear fruit.
Tomorrow is the cold dew, what is the weather like there? Is it raining? You are welcome to leave a message in the comment area to discuss!
Summary: "The cold dew freezes the cow to death in the morning, and the cold dew is warm and dry in the evening", the cold dew tomorrow, is the cold dew early or late this year? We can know from the above that this year is the late cold dew, although people feel comfortable, but it is not conducive to the growth of crops.
