The origin of solar terms in Grain Rain;
Grain Rain means "Rain gives birth to hundreds of valleys", and it is Grain Rain when the sun reaches 30 on April 20th or 2 1 day every year. "Twenty-four solar terms" said, "In mid-March, after the rain, the soil paste pulsates, and now it rains, and its valley is in the water ... At this time, the valley is planted from bottom to top", hence the name.
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.
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.
In ancient China, Grain Rain was divided into three stages: "The first stage was the beginning of pingsheng; 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.
Grain Rain is the last solar term in spring. At this time, just after planting seedlings and planting new crops in the field, rain is most needed, so there is a saying that "spring rain is as expensive as oil". At this time, the eastern part of most parts of South China is abundant with rainfall of about 30 to 50 mm in late April of the year. The first heavy rain usually occurs during this period, which is beneficial to rice planting and the growth of corn and cotton at seedling stage.
However, most of the rainfall in other parts of South China is less than 30 mm, so irrigation measures should be taken to alleviate the impact of drought. The mountainous areas in the northwest plateau are still in the dry season, and the precipitation is generally only 5 to 20 mm. The rainfall around Grain Rain in South China often "sneaks into the night with the wind, and moistens things silently" because the frequency of "late rain" is the highest in April and May. "It often rains at night and the river sill is clear", which is very suitable for crop growth and harvest.
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. 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.
