What month's rain

It rains every February 18 or 19 or 20, and ends on March 4 or 5. Rain is the second of the 24 solar terms, which is called "rain". During the rainy season, the temperature rises, the snow melts and the precipitation increases. Rain, like Grain Rain, light snow and heavy snow, is a solar term reflecting precipitation. The rainfall in North China, Northwest China and Huanghuai areas is generally less, so spring irrigation should be organized in time. There is more rain in the area south of Huaihe River, so it is necessary to clear ditches and drain water to eliminate water accumulation in farmland.

The rainy season means that it begins to rain and the rainfall gradually increases. In the Yellow River Basin, the birthplace of the twenty-four solar terms, the weather was cold before it rained, but there were snowflakes flying and the rain was falling, which was unpleasant. After the rain, the temperature can generally rise above 0℃, with less snow and more rain, and the frost period has ended.

Entering the rain solar term, the cold and snowy days have passed in most parts of China, and the temperature has warmed up, which is conducive to the greening or growth of overwintering crops. Therefore, we should pay close attention to the field management of overwintering crops, do a good job in seed selection, spring ploughing, fertilization and other spring ploughing and sowing preparations, and realize "planting a drop in spring and harvesting ten thousand kinds in autumn".

There are three periods of rain, one is when water otters sacrifice fish, the other is when geese come, and the third is when plants sprout. It is said that the solar term of rain has come, the ice on the water surface has melted, and otters have started fishing. Five days after the rain, the geese began to fly back to the north from the south. In five days, plants will begin to sprout as the spirit of the sun rises underground. Since then, the earth has gradually begun to show a thriving scene.
