Tomorrow, April 19 of the Gregorian calendar, the eleventh day of the third month of the lunar calendar, Friday, Gu Yu.
Guyu, as the last solar term of spring, carries people's good expectations for a bumper harvest. Because this solar term indicates the increase in temperature and the increase in precipitation, it is particularly suitable for the growth of crops, especially cereal crops, whether it is sowing, seedling emergence or ear raising. For this reason, there is also a saying that "rain gives birth to a hundred grains".
However, for this solar term, the ancients still have the saying of "three fears", that is, "Gu Yu is most afraid of three days", which means that if the following three types of weather occur on this day of Gu Yu, then this year's crop harvest will be affected. What are the three types of weather, and what are the characteristics? Next, let's take a look at them so that we can prevent them in advance.
The first type: fear of sunny weather
As the saying goes, "Qingming is afraid of rain, and Gu Yu is afraid of sunshine". On the day of the valley rain, the folk believe that they are most afraid of no rain, that is, there will be a sunny day, because this kind of weather will lead to drought and affect the growth of crops.
It is understood that the grain rain solar term, is the rice, corn, cotton and other crops of a large number of sowing season, at this time it is necessary to have sufficient water to ensure the emergence of crops; and after the valley rain is the beginning of summer, at this time the weather temperature will become higher, the ground water vapor evaporation will also become faster, at this time it is necessary to keep the soil moist, so that the crops grow rapidly, so before and after the valley rain, farmers are afraid of encountering sunny days.
Moreover, there is a folk saying that "a rain before and after the valley rain is better than a show to be lifted", which means that it is also the benefit of rain on the day of the valley rain.
In addition, according to historical records, "the valley rains, the valley is born after the rain", that is to say, this solar term needs rain to ensure the growth of crops, otherwise, sunny days cannot allow crops to grow. Therefore, Gu Yu is most afraid of sunny weather.
The second type: fear of wind
As the saying goes, "When the rain blows in the valley, the wind blows, and the wheat harvest decreases." If there is windy weather, it is also a bad signal for crops.
It is understood that in the rainy season, the wheat begins to tassel, and it is very susceptible to strong winds at this time, resulting in lodging and breakage, resulting in a large reduction in harvest yield. And there is the possibility of flooding disasters when the wind blows, just as "the valley rain west wind arrives, the small bridge is submerged", "the valley rain south wind rises, and the dog days are more rainy" said, if the valley rain encounters such a windy weather before and after, then the next rainfall may be a lot, and even the possibility of heavy rain will cause the small bridge to be submerged, so that the crops will also suffer from waterlogging and reduce yield.
In addition, there is a saying that "when the wind blows in the valley, it will be cold until the middle of June", which means that if the wind blows on the day of the valley rain, then the following days will be very cold, so that the sown grain will suffer frostbite, and in severe cases, it will lead to no harvest. Therefore, the common people are afraid of the rain and wind.
The third type: fear of cooling
There is a saying in the agricultural proverb, "When the rain in the valley sees frost, the wheat seedlings suffer." If there is early frost weather, it means that there is a cooling, and at the same time it means that it is an abnormal weather at this time, which does not conform to the laws of nature, which also indicates that this year's year is not good, and disasters are prone to occur, so the crops will also be in danger.
And this phenomenon is commonly known as "inverted spring cold". The inverted spring cold occurs from March to May in the Gregorian calendar, especially in mid-to-late April, when the weather is warming up, often due to the invasion of cold air, resulting in warm in the early stage and cold in the later stage, and the temperature will also drop sharply, which can easily lead to the freezing of crops.
It is understood that the wheat at this time is the heading season, and all kinds of fruit trees are also in the pollination and fruit setting period, the need for a suitable temperature to support heading, pollination, fruit set, and once the weather is cooled, then it is bound to cause these crops to be difficult to pollinate, and even frostbite, so that the harvest of a stubble will be gone. Therefore, people are also afraid of sudden cooling.
In general, the "three fears" of the Guyu solar term come out, that is, fear of sunny weather, fear of wind, and fear of cooling. According to the experience of the ancients, as long as these three types of weather are not encountered before and after the valley rain, then this year will be a good year, and the crops will be harvested.
Of course, these statements are based on the experience of the ancients, there is a certain degree of uncertainty in itself, and there is no substantial scientific basis, and even has a strong regionality, so we should learn and understand at the same time, or take the actual situation as the standard, try to check the weather forecast as much as possible, and then combine with agricultural proverbs, so as to better judge the future weather conditions, in order to be fully prepared.
Okay, the above is what I told you today about Gu Yusan's fears. In other words, do you think what the ancients said is reasonable? What is the weather like over there? Are there any of the above three kinds of weather? You can leave a message or comment to share with you the situation over there. #春日生活打卡季 ##挑战30天在头条写日记#
