A 50-word introduction to Grain Rain.

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.
