Get up this morning, pick up the mobile phone, jingle, the mobile phone popped up a message, I habitually glanced down, it turned out to be a low temperature rain and snow freezing disaster warning message, it is expected that from the 22nd to the 23rd, there will be a rain and snow process in the Dabie Mountains and along the river, of which, on the 22nd, the heavy snow in the south of the Jiangnan, the local blizzard, the minimum temperature in the morning of the 24th, the Dabie Mountains and the southern Anhui region -6 ° C to -8 ° C, the north of the Huai River -3 ° C to -1 ° C, the other -5 ° C to -3 ° C, pay attention to the cold and warmth measures, now the rain has passed , the temperature should have climbed, but at this time it snowed three times in a row, the temperature dropped below 0 ° C, not only people can not eat, cold and fever, even the crops in the field can not come, "pour spring cold" board nailed?
Our old farmers are not afraid of suffering and tired, but they are afraid of the weather is not strong, although most people go out to work, but the land at home is also planted with crops, wheat has returned to green growth, peas also stretch out tentacles, as well as just sprouted peach trees, cherry trees, this rain and snow weather suddenly arrived, crops can be reduced, especially vegetables in the greenhouse, if the blizzard comes, the collapsed greenhouse, the consequences are unimaginable, this "eight or nine" weather and blizzard, what is the omen? The ancients did not have weather forecasts, how did they conclude? Let's see what the saying goes.
First, the curtains are hung in the rainy season, and there is a cold spring in March
This saying means that when the rain is in season, the eaves are frozen into an ice ridge, then in March there will be a spring cold, we know that the rain festival is already the second solar term of spring, at this time the temperature rises, because the cold air is still not willing to go downwind, everywhere south, the cold and warm currents intersect into rainwater, which is very important for crops, as the saying goes, "spring rain is as expensive as oil", so the rain festival is appropriate to rain, which is a sign of a bumper harvest.
However, the rain festival has snowed heavily, then the temperature is quite cold, the snow accumulates, the sun melts into water after it comes out, the temperature is low in the morning and evening, there is ice under the eaves, and in March, the ice and snow still will not leave, that is, the so-called "inverted spring cold", which is very unfavorable to crop growth, crop yield reduction is inevitable, this is also the most feared thing of the ancients, it heralds the advent of the disaster year, after all, it is living on farming, which means hungry stomach and difficult life.
Second, the snow fell eight or nine heads, and the spring was cold
The meaning of this saying is that when heavy snow occurs at the beginning of "eight or nine", then the temperature will be very cold throughout the spring, because the spring begins in the spring and ends with the valley rain, which is more than two months, and the winter nine nine song "Seven nine rivers open, eight nine geese come, nine nine plus one nine, ploughing cattle everywhere." From here, it can be seen that the swallows have flown back at the time of "Eighty-Nine", indicating that the temperature has risen and the earth is also thriving, a bright spring scene.
But eight or nine times, suddenly a heavy snow came, then the next time of spring, basically spent in the cold weather, not only the human body is easy to get sick, and crops will also be frost damage, people need to add clothes in time to keep cold, while taking warm measures for crops, from the invasion of freezing.
Third, the rain fell snow, and the shade was cold to the valley rain
This saying means that when the rain is in season, the heavens and the earth are fluttering snowflakes, so that for the next period of time, the weather will be cloudy and cold, until the valley rain festival, we know that the valley rain festival is the last festival of spring, after the valley rain festival, it will also enter the summer, which means that the spring will be spent in the cold.
Spring is originally drought and little rain, if the spring rain and snow flood, then in the summer, the rain will be more frequent, because the origin of the valley rain festival is increased rainfall, aquatic things, so at this time to prepare for drainage in advance, so as not to flood crops, resulting in crop yield reduction, which is also the most worrying of the ancients.
In short, the rain and snow are coming again, and the "spring cold" is nailed down? These sayings tell us that this spring will not be warm, we should do a good job of keeping warm measures to avoid freezing colds, and at the same time, we must also take timely measures against crops to avoid frost damage and jointly resist the invasion of "spring cold".
