Grain Rain is the sixth of the 24 solar terms in Grain Rain after Tomb-Sweeping Day. Every year from April 19 to April 2 1 day, when the sun reaches the longitude of 30 degrees of the Yellow River, it is Grain Rain, which comes from the old saying "Rain gives birth to hundreds of valleys". At the same time, it is also the best time to sow and transplant seedlings. Grain Rain has high temperature and frequent rainfall. 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. 2016165438+1October 30th, China's "Twenty-four solar terms" was officially listed in the UN Intangible Heritage List.
The weather characteristics of Grain Rain in ancient China and Grain Rain can be divided into three periods: "The first period was when duckweed 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.
After the solar term in Grain Rain, rainfall increased, and rain gave birth to hundreds of valleys. With sufficient and timely rainfall, cereal crops thrive. In the southern region where the grain is abundant, "when the flowers fall, the cuckoo cries at night, the peony blooms and the cherry is 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. High temperatures above 30℃ often occur in eastern South China for a day or two, which makes people feel very hot. Low-altitude valley areas are used to enter summer. The climate characteristics of high temperature in south China in spring are beneficial to the early cropping cultivation measures in Da Chun. The suitable planting temperature of Polygonum cuspidatum is 65438 08℃ to 22℃, which can be satisfied at this time. The experience in the old arid areas in southern China has proved that planting Osmunda japonica early in Grain Rain can seal vine leaves before summer drought, enhance drought resistance and achieve high and stable yield.
"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".

Most of the weather proverbs in Grain Rain Festival revolve around the center of rain but no rain, such as "Grain Rain is gloomy, and it rains in summer" and "Grain Rain is rainy, and there is no dry soil for forty-five days". 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. The vast rural areas should do a good job in the prevention and control of wheat diseases and insect pests according to the weather changes.
The custom in Grain Rain is April 20th every year, which is the Fisherman's Day in Rongcheng. This festival originated from Grain Rain Festival. Fishermen in the northern coastal areas of China have celebrated Grain Rain Festival for more than 2,000 years, and it was renamed Fisherman's Day in Daoguang period of Qing Dynasty (182 1). On this day in Grain Rain, fishermen in Shandong coastal areas prayed for the blessing of Poseidon, smooth sailing and a bumper harvest of fish and shrimp. Therefore, today, wealthy fishermen in Rongcheng held a grand "sea sacrifice" activity in the Grain Rain, toasted Poseidon, and then set sail for fishing.

Shaanxi Fengxiang Scorpion Curse is woodcut, which shows that there is a great demand. It was printed with the words: "In Grain Rain, in mid-March, scorpions showed off their bravado. God chicken bites, poisonous insects turn into water ... "In the center of the picture, the rooster holds the insect with a big scorpion under his paw. This painting is printed with a spell. The saying that the rooster cures the scorpion has been circulating among the people for a long time. Back to the fifty-fifth ghost story novel of Journey to the West, the Monkey King Pig Bajie is no match for Scorpion Essence, and Guanyin knows that he can't get close to him. So we had to ask the Monkey King to invite Pleiadian officials, and it succeeded. Pleiadian officials were originally a rooster with two crowns. It is described in the book that the Pleiadian star official showed his prototype-the rooster, and the rooster called out to the scorpion essence, and the scorpion essence immediately showed its prototype, which was a scorpion the size of a pipa. The cock crowed again, and the scorpion died delicate on the hillside. Scorpions are also forbidden in Shandong folk customs. Xiajin county annals in the sixth year of Qing Qianlong: "Grain Rain, cinnabar forbids scorpions." The folk custom of "banning scorpions" reflects people's feelings of expelling pests and longing for harvest and peace.
