Introduction of rainwater solar terms
The birthplace of solar terms is the Yellow River Basin. It was very cold before it rained, but it was snowing and the rain was terrible. After the rain, the temperature can generally rise above 0℃, with less snow and more rain. However, in the warm climate of Sichuan Basin, even in the dead of winter, rainfall is not uncommon. During this period, the average temperature in Sichuan Basin is mostly above 10℃, with peaches and plums in bud and cherries in full bloom. It is indeed a climatic spring. Except for a few years, the frost period is over. It is timely to graft fruit trees and plant trees. After the dry winter, there are many droughts in spring in the basin all the year round, especially in the west of the basin, and the spring rain is as expensive as oil.
Rain and solar terms, agriculture should pay attention to moisture conservation and timely irrigation to meet the water supply at the jointing and booting stage of wheat and the critical period of bolting and flowering of rape. The mountainous area of western Sichuan Plateau is still in the dry season, with low temperature and high wind speed, which is prone to forest fires. In addition, the invasion of cold wave will cause strong cooling and snowstorm, which will do great harm to the old, weak and young animals. These should pay special attention to prevention. Time flies, the four seasons remind people, and the plan for a year lies in spring. The management of Koharu and the preparations for Da Chun should be carried out quickly, so as to make this year better than previous years.
