What's the saying about cold dew?

1, he is afraid of cold dew, and people are afraid of being old and poor.

There is a folk saying that "he is afraid of cold dew, and people are afraid of being old and poor." This sentence is about the harm of "cold dew wind", which is the cold air that appears before and after cold dew. Generally speaking, the influence of cold dew wind will be adapted to local conditions, and will vary with different grain varieties.

On the day of cold dew, people will get up early, and then give incense to the gods and buddhas, asking them to bless the cold dew with good weather and abundant crops, and not to be attacked by the cold dew wind. In order to solve the harm of cold dew wind to grain, people will also irrigate when cold dew wind comes to reduce the harm of cold dew wind to grain production reduction.

2. If it rains in the cold open air, there will be less rain in winter; It doesn't rain in the cold open air, but it rains a lot in winter.

This is an agricultural proverb, which predicts the rainfall in winter through the weather conditions on the day of the cold dew solar term. The literal meaning is also relatively simple. It means that if it rains on the day of the cold dew solar term, there will be less rain (snow) in winter. On the contrary, if the weather is sunny in the cold and dew solar terms, there will be more rain (snow) in winter.

There are more rainy (snowy) days in winter, which is beneficial to the growth of crops such as winter wheat and rape. Therefore, farmers don't expect it to rain in the cold dew solar terms, because it indicates that there is less rain in winter and the harvest in the coming year will be affected to some extent. There is also a similar agricultural proverb in Guangxi, "There is rain in cold dew, little rain in winter, no rain in cold dew and much rain in winter".

Characteristics of cold dew solar terms

1, meteorological change characteristics: in cold dew season, dew increases and temperature decreases. At this time, frost will appear in some parts of China. In the north, it is already a scene of late autumn, with white clouds and red leaves and occasional early frost. In the south, autumn is getting stronger and cicadas are dying. Traditionally, China thought "dew" was a symbol of cold weather. The solar term of the Mid-Autumn White Dew is "dew condenses white", and it is already "dew cold, it will condense into frost" when it is cold in season and autumn.

2. Phenological characteristics: The ancients in China divided cold dew into three periods: one was Hongyan guest; Second, the sparrow enters the water and becomes a clam; Three chrysanthemums have yellow flowers. It means that in this solar term, geese move south in a line or herringbone queue; In the cold late autumn, all the birds disappeared. The ancients saw a large number of clams suddenly appearing on the seashore. The stripes and colors of shells were very similar to those of birds, and they thought they were birds. "Chrysanthemums begin to blossom" means that chrysanthemums have opened in a large area at this time.

3. Characteristics of farming activities: After the cold dew, if there is strong cold air going south, the cold dew wind weather with low temperature and strong wind is easy to appear in the south. This weather is very harmful to double-cropping late rice. In the cold dew season, wheat should be sown in the north, not late, so as not to reduce production. South China should sow rape and plant broad beans in due course.
