Guyu, the 6th solar term of the 24 solar terms, is held on April 19-21 of the Gregorian calendar every year. The precipitation increases significantly during the rainy season, which is a busy period for spring plowing and spring planting. Crops in the field, whether winter wheat or spring crops, as well as vegetables and fruits, need sufficient water to ensure normal growth.
The so-called "rain gives birth to a hundred grains" reflects the significance of grain rain to the agricultural climate. The ancients said that "the most afraid of the valley rain is sunny day", the meaning is very easy to explain, if the day of the valley rain is sunny, the subsequent weather is not conducive to the growth of crops, this is the experience that people have summed up after perennial observation.
Some friends may ask, why don't you want Gu Yu to be sunny, but hope to be rainy? In this article, the author will talk to you in detail about this matter through the agricultural proverbs that have been circulated among the people, and you will understand it after reading it.
"Valley rain no rain dry river bottom"
This agricultural proverb means that if there is no rain during the rainy season, then the weather is likely to be mainly sunny, and the rivers will gradually dry up due to the lack of rainwater, leading to drought.
During the valley rain period, the demand for water of crops gradually increases, and if the rainfall is abundant at this time, it is conducive to the growth and development of crops. Conversely, if there is no rain during the rainy season, crops will face water shortages and growth will be suppressed, which may lead to reduced yields or poor harvests.
In addition, the rainfall during the valley rain season also has a certain impact on the amount of water in the river. If there is not enough rainfall, the amount of water in the river will gradually decrease and may even dry up. It not only affects the supply of agricultural irrigation and domestic water, but also may have a negative impact on the ecological environment.
Therefore, judging from this agricultural proverb alone, if the valley rain does not rain, it indicates that the subsequent rain is relatively less, and when planting the land in the past, there is no current irrigation equipment.
"There was no rain in the valley, and then I cried the rain"
"No rain in the valley" means that no rain fell from the sky during the critical period of the valley rain, which is unfavorable news for the ancient farmers who relied on the sky to cultivate the earth. When the soil is dry due to lack of water, it will lead to slow growth of crops, or even direct drying and death of seedlings.
"Crying Rain Later" is a visual description of the consequences of "no rain in the valley". If there is no rain during the rainy season, then farmers will worry about the subsequent rainfall. To pray for rain, farmers may perform some traditional rain prayer rituals, crying and praying for rain from heaven to save the crops that are about to wither.
From the perspective of agricultural planting, rainfall during the rainy season is essential for the growth of crops, which not only provides sufficient water for crops, but also improves soil moisture and permeability, which is conducive to the growth of crop roots and nutrient absorption.
Therefore, from the analysis of the agricultural proverb "no rain in the valley, crying rain later", it is a good thing for the rain to rain in the valley, and it is a sunny day for fear, on the other hand, the rain in the valley is a sunny day, which also indicates that the subsequent rainfall is relatively small, and the crops cannot grow normally due to lack of water.
"When the rain in the valley meets the rain, a moment is worth a thousand gold"
This agricultural proverb means that in the rainy season, if it coincides with rainfall, then for agricultural production, the rain at this moment is worth a thousand gold, although it is an exaggeration, but it is a good expression of the importance of rain.
Let's first understand the meaning of "valley rain" and "falling rain". Guyu is one of the 24 solar terms, and "falling rain" refers to rainfall. "Gu Yu meets falling rain" refers to the rain that is encountered during the season of Gu Yu.
Why is it "worth a thousand gold"? This is mainly due to the dependence of agricultural production on water. During the rainy season, it is the winter crops of the previous year that grow vigorously. As well as the critical period of sowing and seedling emergence of spring-sown crops, the demand for water is relatively large.
If the rainfall is moderate at this time, it can not only meet the growth needs of crops, but also help improve soil fertility and promote crop growth. Therefore, for farmers, the rain during the rainy season is precious.
On the contrary, if it is a sunny day, it indicates a drought, and if the water is not replenished in time, it will not only affect the booting and heading of winter wheat, but also reduce the emergence rate of spring maize, or the growth of seedlings (easy to yellow).
Therefore, the agricultural proverb "When the rain in the valley meets the rain, a moment is worth a thousand gold" also shows from another perspective that farmers are afraid that the rain is sunny, and they like the rain to be rainy.
The above three agricultural proverbs, "Gu Yu has no rain and dry river bottom", "Gu Yu has no rain, and then cry rain", "Gu Yu meets rain, a moment is worth a thousand gold", the meaning of the meaning actually points to one point, that is, the Gu Yu solar term is suitable for rain, but not for sunny days.
From the perspective of agricultural planting, from the standpoint of farmers, rainy days are more happy, and sunny days are more afraid, which is the reason why "the most afraid of valley rain and sunny days".
Of course, there are two sides to everything, and the answer is not absolute, with the change of the environment and climate, the weather is still based on the local weather forecast.
Today's valley rain solar term, we are here on a rainy day, where are you?
