What festivals in China are related to agricultural traditions?

Grain Rain (April 22), Xiaoman (May 22) and Mangzhong (June 7) were in the middle of March. After the rain, the soil and paste pulsated, and now it rains in the valley. Rain is silent, just like the rain in my field. At this time, cover the grain and sow, from top to bottom. "At this time, the weather is mild and the rainfall has increased significantly, which has a lot to do with the growth and development of cereal crops. Appropriate rainfall is beneficial to the greening and jointing of overwintering crops and the sowing and emergence of spring sowing 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, the cuckoo blows feathers; Third, 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. Full grain buds-refers to the full seeds of summer crops, but not yet mature, just full, not yet full. Every year on May 2 1 day of the Gregorian calendar, it is full. In ancient China, Xiaoman was divided into three stages: "Bitter vegetable show"; Second, waiting for grass to die; Waiting for the arrival of autumn wheat. "That is to say, in Xiaoman solar terms, bitter vegetables have flourished; Some grass with soft branches and like shade began to die in the strong sunlight; At this time, the wheat began to mature. Crops with awns, such as awn seed wheat, mature and summer sowing begins. It is the ninth solar term among the twenty-four solar terms, and it is the awn species around June 5 every year. The sun reaches 75 degrees of the yellow meridian. " Twenty-four solar terms: "The May Festival means that there are awn crops in the valley". It means that the seeds of crops with awns, such as barley and wheat, are ripe and it is very urgent to grab the harvest. Summer sowing crops such as late rice, millet and millet are also the busiest season for sowing, so they are also called "awn seeds". Spring competes for the sun, and summer competes for the time. "Race against time" refers to the busy farming season at this time. People often say that the "three summers" are busy farming seasons, that is, summer management is busy with summer harvest, summer sowing and spring sowing crops. Therefore, "busy", also known as "busy planting", is the busiest time for farmers to sow and go to the fields. In ancient China, mango seeds were divided into three stages: "One stage was when mantis was born; Second, wait for Peng to start singing; The third-class tongue is silent. " In this solar term, the eggs laid by mantis in late autumn last year, because they felt the birth of Yin Qi, broke their shells and gave birth to little mantis; Shady shrike birds began to appear in the branches and sing in the shade; On the contrary, mockingbirds, who can learn from the songs of other birds, stop singing because they feel the appearance of Yin Qi.
