Snow breaks in Qingming Festival, and frost breaks in Grain Rain.

It is the sixth of the 24 solar terms. From April 19 to April 2 1 every year, Grain Rain is regarded as the time when the sun reaches 30 degrees of the yellow meridian, which comes from the old saying that "rain gives birth to hundreds of valleys". At the same time, it is also the best time for sowing, transplanting and ordering beans. According to meteorologists, Grain Rain is the last solar term in spring, and the arrival of Grain Rain solar term means that the cold wave weather is basically over and the temperature rises faster, which is very beneficial to the growth of cereal crops.

But it hasn't been like this for years The day before Grain Rain, it was still raining and snowing. The temperature is falling instead of rising, as if it were winter again.

"In mid-March, since the rain began, the soil paste has been pulsating, and today the rain is in the valley of water. Rain is silent, just like the rain in my field. At this time, cover the valley and sow, from top to bottom. " At this time, the weather is mild and the rainfall increases obviously, which has a great relationship with the growth and development of cereal crops. Appropriate rainfall is beneficial to rejuvenation and jointing of overwintering crops and sowing and emergence of spring crops. In ancient times, the so-called "rain gives birth to hundreds of valleys" embodies the significance of modern agricultural climate of "Grain Rain". However, too much rain or severe drought will often cause harm and affect the later yield. Grain Rain is in the middle and lower reaches of the Yellow River, which not only points out its agricultural significance, but also shows that "spring rain is as expensive as oil".

In ancient China, Grain Rain was divided into three stages: "The first stage was when Ping was born; The second time, pigeons blow feathers; The third is that Dai Sheng fell to Sang. " After Grain Rain, rainfall increased, duckweed began to grow, then cuckoo began to remind people to sow, and then Dai Sheng birds began to be seen on mulberry trees.

"Before Grain Rain, cotton was well planted", as the saying goes, "Grain Rain doesn't grow flowers, and its heart is like a crab crawling". Since ancient times, cotton farmers have regarded Grain Rain Festival as an indicator of cotton planting, compiled proverbs and passed them down from generation to generation.

Most weather proverbs of Grain Rain Festival revolve around the center of rain but no rain, such as "Grain Rain is gloomy, it rains in summer", "Grain Rain rains, and there is no dry soil for forty-five days" and so on. There are also solar terms in Grain Rain, such as high temperature and frequent rainy days, which will cause the occurrence and prevalence of pests and diseases of wheat.

I hope the weather in Grain Rain will get warmer gradually in the future, and it will not be better than winter.

The Great Cold is the last of the 24 solar terms, which is around 65438+1October 20th every year. During the severe cold, the sun reaches 300 degrees of the yellow meridian. Twenty-four solar terms: "In mid-December, I met before (slight cold)." Time-sharing, time-sharing, time-sharing and time-sharing quote three rites and meanings: "Great cold is the middle, shaped by slight cold, so it is called great ... extremely cold, so it is called great cold." At this time, the cold wave frequently goes south, which is the coldest period of the year in most parts of China. The wind is strong, the temperature is low, and the snow on the ground does not melt, showing a cold scene of ice and snow.

In ancient China, the Great Cold was divided into three stages: "One stage is chicken milk; Second, the symptoms of bird disease; Three times, the water is strong. " In other words, in the great cold solar terms, chicks can be hatched; Falcons such as eagles are in a state of strong predation ability, hovering in the air to find food to supplement their body energy to resist the cold; In the last five days of the year, the ice in the water has frozen to the center of the water, and it is the strongest and thickest.

Agriculture should strengthen the cold and antifreeze of livestock and wintering crops.

Today, although it is beginning of autumn, the weather is as hot as summer. I wish it would rain cats and dogs at once and give the earth and crops a good drink. However, God kept a straight face.

Alas, if only the weather could be carried out according to the season! In spring, warm wind blows, everything begins to grow, people travel everywhere, children fly kites, and beautiful scenery is better than pictures. What a good season! Moreover, spring is the beginning of a year, and people take the time to make a good start of the year. In summer, although the weather is hot, crops grow vigorously and lotus flowers fill the pool. In the evening, people come to the roadside, chat under trees and bamboo forests, tell stories, eat watermelons and play chess. What a happy season! In autumn, the weather is cool, the fields are golden and the fruits are ripe for people to taste. What a comfortable season it is! In winter, it snows heavily. Although the weather is cold, we are not afraid! We bravely went out to play with snow, have snowball fights, make snowmen and build snow bridges in the fields ... what an enviable season! Every season is really satisfying. However, if you are extraordinary, you will go to the opposite side. If only we could control the seasons!
