In Grain Rain season, in the south of China, "a hundred flowers blossom", willows fall, cuckoos cry at night, peonies bloom and cherries are ripe. The natural scenery tells people that it is late spring. At this time, the temperature in the south rises rapidly. Generally, in late April, except for parts of northern and western South China, the average temperature has reached 20℃ to 22℃, which is more than 2℃ higher than that in mid-April. In the eastern part of South China, there is often a high temperature above 30 for a day or two, which makes people feel very hot. Low-altitude valley areas have also entered summer.

In ancient China, Grain Rain was divided into three stages: "The first stage was when Ping was born; The second time, the cuckoo blows feathers; The third class is Dai Ren's surrender. " 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.

During the Grain Rain solar term, the westerly jet in East Asia will weaken and move northward again, the warm and humid air mass in South China will become more active, the circulation fluctuation in the westerly belt from west to east will become more frequent, and the activities of low pressure and Jianghuai cyclone will gradually increase. Affected by it, there will be continuous rain or heavy wind and rain in the Jianghuai area.

Knowledge of the origin of Grain Rain II. The development history of Grain Rain.

About 4,000 years ago, the Yellow Emperor Xuanyuan was acclaimed by tribal leaders as the leader of the tribal alliance, and he named Cang Xie Zuo Shi. After Cang Xie became a historian, he used different kinds of shells and knots as markers to record events. However, as Cang Xie is responsible for more and more affairs, the old methods are far from meeting the demand, and Cang Xie is very worried.

Every year, Grain Rain Festival, Cang Xie Temple will hold a traditional temple fair, which lasts for seven to ten days. Year after year, thousands of people come here from all directions to hold a grand and warm ceremony of entering the temple and a grand and solemn memorial ceremony to commemorate and sacrifice Cang Xie, the father of Chinese characters. People dance yangko, run bamboo horses, play social fire, perform martial arts, beat gongs and drums, perform drama, sing and dance to express their respect and nostalgia for Cang Sheng. Troupe and business also came to join in the fun, very lively. Cangjie Temple Fair has become a grand local festival.

The historical record of Grain Rain.

"Tongwei Filial Piety Helps the Gods": "In the fifteenth day after the Qingming Festival, the bucket refers to Chen and is Grain Rain. In mid-March, it is said that the rain gives birth to hundreds of valleys, which are clean and bright. "

Qunfangpu: "Grain Rain, the valley is born with the rain." Before and after Grain Rain, the weather turned warmer and the rainfall increased, which was beneficial to the sowing and growth of spring crops.

Twenty-four solar terms: "In mid-March, after the rain, the earth's paste pulsates, and now it rains its valley in 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".
