Gu Yu has "three fears"? Today's valley rain, what do you mean by three fears? What are the characteristics of the valley rainy season?
On April 20, 2022, at 10:24:07 a.m., the mainland officially ushered in the Valley Rain Festival. Gu Yu, is the sixth of the twenty-four solar terms in the mainland, with the meaning of "rain born of a hundred valleys", Gu Yu, is also the last solar term of spring, which also means that Summer is coming!
Like rainwater, valley rain is also a solar term that reflects the phenomenon of precipitation. Whether it rains in the valley or not, whether it rains or sunny days is good, there are sayings in the farming culture of the mainland. For example, the folk saying that "the valley rain is gloomy, and the summer rain is drenched", which is to tell people that the valley season is rainy and rainy, and there will be more rain in the summer.
It is also said that "Qingming should be sunny, and the valley rain should be drenched." The valley rained without rain, and then wept rain. "It means that the Qingming weather is better, the rainy day of the valley is better, if there is no rain in the valley rain, the rain behind will be relatively small, it is easy to produce drought, and the harm of drought to agriculture is relatively large." Like henan, Hebei, Shanxi, Shaanxi and other places in the north of the mainland recently, they are relatively arid and urgently need rain to quench their thirst.
Everyone has heard the saying that "spring rain is as expensive as oil", and when it comes to the valley rainy season, it is the time when the seedlings are growing, people plant melons and beans and plant corn, and the demand for rainwater is also more urgent, which shows that the rain in the valley rain season is more good. Generally speaking, after the valley rain, the temperature in the south will become warmer, and the rain will also increase, which is why people arrange melon beans to be planted at this time.
During the valley rainy season, if you encounter the following situations, people will also be worried, which is what people often say that the valley rain has "three fears", which "three fears" is it? Let's take a look
First, fear of low temperatures
The valley rain is already the last season of spring, and if the cultivation misses this opportunity, the harvest may not be too good, and it may affect the planting of the next season. However, the harm of low temperatures to agriculture is very large. As mentioned earlier, people will arrange for many crops to be planted at this time.
Not long ago in our country there was a large-scale spring cold weather, the temperature in many areas is far lower than the same period of the year, if the crop is planted at this time or just planted, the survival rate is relatively low, not to mention the harvest, the harvest is possible. I believe that everyone also knows how harmful the severe spring cold is. Therefore, during the rainy season in the valley, I am afraid of encountering severe cold spring weather.
Second: Fear of high winds
Many spring gales are related to strong convective weather, not long ago a strong cold air, not only brought about a multi-day inverted spring cold weather, but also stimulated a fierce strong convective weather, accompanied by short-term strong precipitation, thunderstorms and hail appeared, like a record wind in Sichuan, reaching a level 13 typhoon, extremely destructive. Of course, this is a special case, but it is the general wind, which also has a relatively large impact on agriculture, and it is easy to blow crops down, while some crops that have just been planted have not yet grown steadily, and the harm is greater.
Third, I am afraid that it will not rain
As mentioned earlier, the need for rain in the valley is more urgent, many crops are sown after the arrival of rain, and wheat in the north also needs rain to water in order to thrive. If there is little rain in the valley rainy season, if it is too dry, it is a very worrying thing for the farmers. The rainy season in the valley is the spring ploughing season in many areas, and it needs to be moistened by rainwater.
Today is valley rain, but we can't judge by the rain of the day, after all, there will be a lot of uncertainty. We can take a look at the precipitation on the mainland in the next ten days, and the precipitation in the southern region is still very rich. This is more consistent with the weather characteristics of the rainy season of the mainland's perennial valleys, and it is not dry, but some areas in North China, Northwest China and other places have less rain, and some areas are now relatively dry, and the drought without rain will be aggravated, and it is necessary to strengthen drought resistance.
