What does the rain solar term mean?

There are two meanings: one is that the weather is getting warmer, and the other is that there is less snow and more rain in the form of precipitation.

The rain solar term generally starts from February 18 to 20 and ends on March 4 or 5. In rainy and solar terms, the direct point of the sun is gradually approaching the equator from the southern hemisphere. At this time, the sunshine hours and intensity in the northern hemisphere are increasing, and the temperature is rising rapidly. Warm and humid air from the ocean becomes active and gradually pushes northward to meet with cold air, forming rainfall. But the rainfall level is mainly light rain or Mao Mao rain.

Agricultural activities of rain and solar terms

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".

The rainfall in North China, Northwest China and Huanghuai areas is generally less at this time, so spring irrigation should be organized in time. There is more rain in the area south of Huaihe River, so it is necessary to do a good job of ditch cleaning, drainage and intertillage weeding to prevent wet damage and root rot.
