Will the temperature stabilize after dew becomes a solar term in Grain Rain, first frost? The temperature changes these days are like this

In a blink of an eye, the Grain Rain solar term in spring has arrived again. 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 stage is from Dai Sheng to Sangzi. 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. So what is the temperature change during this time?

When dew becomes a solar term in first frost and Grain Rain, the temperature will stabilize.

After Grain Rain, the temperature will stabilize in spring. The average temperature in Grain Rain is about 23 degrees. In Grain Rain season, in the south of China, "a hundred flowers blossom", willow leaves fall, cuckoo cries at night, peony bloom and cherry ripens. 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. Go out and do a good job of sun protection.

The temperature change in spring is also very interesting. Grain Rain is the sixth solar term among the 24 solar terms, and it is also the last solar term that marks spring. According to astronomy, the sun runs on the ecliptic in Grain Rain. When it reaches 30 degrees, it usually falls in April 19-2 1 every year. The festival time in Grain Rain this year is April 20th 17: 42. At this time, the crops in the field need rain to moisten them. There is a saying that "Spring rain is as expensive as oil". In ancient China, agriculture depended on the weather. Only when it rains can hundreds of valleys on the ground grow. At this time, there is more and more rain, and a bumper harvest is in sight. So it was named 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. So we can draw a conclusion that this time period is suitable for planting.

The temperature will be higher in the south. 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. 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.
