Now that it has entered the twilight of spring, the weather is getting warmer and warmer, and the daily maximum temperature in some areas of the mainland has exceeded 30 °C, and many people have already felt the breath of summer. As the old saying goes, "it should be cold or not cold, and the grains should not bear fruit if it is not hot", which means that it is not a good thing to be too warm in winter, and too warm in winter will lead to increased evaporation of soil moisture, which can easily cause drought, and too warm in winter is also conducive to overwintering of pests, which will lead to a high incidence of pests and diseases in the coming year;
Summer temperatures are supposed to be hot, but it's not a good thing that summers are unusually hot. Too hot in summer will lead to the occurrence of symptoms such as fatigue, loss of appetite, heat stroke, etc., which will lead to an increase in the probability of drought, which is not conducive to people's production and life. For example, there was a "heat disaster" during the Qing Dynasty on the mainland, and the "Fushan County Chronicle" recorded: "It was hot in summer and May, and there were many pedestrians on the road, and the Beijing division was even worse, and the floating people in Beijing also had heat death", which is said to be the eight years of Qianlong, many people in the capital area died of heat, according to the conversion of paleoclimatologists, on July 25, 1743, the highest temperature in the area of Beijing reached an astonishing 44.4 °C, which far exceeded the limit that the human body could bear.
So will it be so hot that we cry this summer? The mainland is an ancient country of agricultural civilization, and our ancestors summed up very rich experience in long-term labor and production, and these experiences can guide us well in production and life.
1. How cold is it in winter and how hot it is in summer
According to the ancient philosophy of the mainland, everything in the world is always in a state of equilibrium with each other, and if the winter is too cold, then it also indicates that the temperature will be too hot in summer.
Therefore, we can roughly judge whether the summer is hot or not from the cold and warm in winter, if the temperature in your local winter is significantly warmer than in previous years, then it also indicates that it will be relatively cool in summer;
Second, the small cold and the big cold do not snow, and the small summer and big summer fields crack
According to the experience of our ancestors, if there is no snow in the Xiaohan and Dahan solar terms, then it indicates that there is very little rain in the next year's Xiaoxia and Da Xia solar terms, and the soil will crack due to drought.
The cracking of the soil during the small and large summer solar terms indicates that the weather is mainly sunny, which also indirectly indicates that the small summer and large summer solar terms are high temperature and little rain, that is, the summer will be very hot. If the summer is too hot, it is easy to cause drought, which will lead to a serious reduction in crop yields, so it is a bad sign that there will be no snow during the small cold and big cold solar terms.
3. The sun laughs on March 3, and the fire burns on June 6
The third day of the third month of the lunar calendar is the traditional Shangsi Festival in the mainland, on which ancient people would go to the water's edge to bathe and bend the water to pray for the removal of bad luck.
According to the experience of our ancestors, if the third day of the third month of the lunar calendar is a sunny day, then it indicates that it will be very hot on the sixth day of the sixth month of the lunar calendar. June 6 is in the dog days, and the fact that June 6 is very hot also indirectly indicates that dog days are very hot.
Fourth, the male is hot and the cow is dead, and the female is cold
Dog days are the hottest time of the year on the mainland, if the dog days are hot, it means that the summer is hot, and if the dog days are cooler, then it is a cold summer.
The dog days include the first volt, the middle volt, and the last volt, in which the first volt and the last volt are fixed 10 days, and the middle volt has 10 days in some years and 20 days in some years, which depends on the early and late ambush time, and the ambush time is early, then the middle volt must have 20 days. The folk proverb says that "the summer solstice three Geng changes into the ambush, and the autumn after the one Geng enters the last volt", which means that the third Geng day after the summer solstice is the time of the ambush, and the first Geng day after the beginning of the autumn is the time of the end of the ambush, and the middle ambush is between the first volt and the last volt.
The summer solstice is on June 21 this year, the first Geng day after the summer solstice is on June 25 (Gengshen Day), and the third Geng day after the summer solstice is on July 15, which is the time of ambush. This year's dog days will be the first volt from July 15, 2024 to July 24, 2024, the middle volt from July 25, 2024 to August 13, 2024, and the last dog day from August 14, 2024 to August 23, 2024.
If it is a dog day, then according to the experience of our ancestors, it indicates that the dog days will be very hot, and if it is the mother volt, then it indicates that the dog days will be relatively cool. The words "hot cow" and "cool cow" are both exaggerated expressions in order to highlight how hot or cold the temperature is.
July 15 this year, this day is the tenth day of the sixth month of the lunar calendar, according to our ancestors, if the lunar calendar date on the day of the ambush is an even number, then it is the mother volt; if the lunar calendar date on the day of the ambush is singular, then it is the male volt, it is obvious that this year's dog days belong to the "mother volt", according to the experience of our ancestors, this year's dog days will not be very hot.
In summary, agricultural proverbs are the experience of our ancestors, which can guide our production and life to a certain extent, but today's climate has already changed, so we can usually pay more attention to the weather forecast, so as to arrange production and life more reasonably.
