What is the solar term after Qingming? What are the characteristics of the climate in Grain Rain?

What is the solar term after Tomb-Sweeping Day? After Tomb-Sweeping Day, it is the solar term in Grain Rain. Grain Rain is the sixth solar term among the 24 solar terms and the last solar term in spring. Grain Rain means "Rain gives birth to hundreds of valleys", and the precipitation has increased obviously at this time. The seedlings in the field are newly planted, and the crops in Xinzhuang need rain most, so the so-called "spring rain is as expensive as oil".

"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, obvious rain often begins to appear in southern China, especially in southern China. Once cold air meets warm and humid air, it will often form a long rainy day. Huaihe river basin is a transitional zone between spring rain in the south and spring drought in the north. From the north of the Huaihe River in Qinling Mountains, the spring rain dropped sharply.

The main feature of the weather in Grain Rain is rainy, which is beneficial to grain growth. 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 rises rapidly. 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". After the solar term in Grain Rain, the rainfall increased and the humidity in the air gradually increased.

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.

Grain Rain's climate is characterized by "snow clearing and frost in Grain Rain". 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.

At this time, the seedlings in the field are planted first, and the 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 in Sichuan, and the river sill has cleared up", which is very suitable for crop growth and harvest.

In Grain Rain, high temperature and frequent rainy weather will lead to the occurrence and prevalence of wheat diseases and insect pests. 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.
