"Twenty-four solar term song" is a small poem compiled for the convenience of remembering the twenty-four solar terms in the ancient calendar of China, and it has been circulated in many versions. Twenty-four solar terms accurately reflect the change of natural rhythm, which has played an important role in the long farming society and has rich cultural connotations. Around the 24 solar terms, a large number of poems and songs have also been produced.
Twenty-four solar terms are the wisdom of ancient people in China. Astronomy, farming, phenology and folklore, spring ploughing, Xia Yun, autumn harvest and winter storage are combined scientifically and skillfully, and a large number of seasonal cultures related to them are derived.
Agricultural irrigation in ancient China depended on precipitation in the sky and rivers on the ground, and farming was mainly concentrated in areas with abundant precipitation and developed river networks. Farmers in these areas are still engaged in agricultural production according to solar terms, temperature and precipitation. In the long farming society, the 24 solar terms play an important role and have rich cultural connotations.
The origin of solar terms:
"Twenty-four solar terms" is the product of ancient farming civilization, which has a long history and is associated with heavenly stems and earthly branches and Bagua.
Agricultural production is closely related to geographical and climatic resources, and superior geographical and climatic resources are important conditions for the birth of agricultural civilization. China is located in the east of Asia-Europe continent and the west coast of the Pacific Ocean, with great differences in thermal properties between land and sea, forming the most typical monsoon climate in the world.
Monsoon climate is a mixture of continental climate and maritime climate. In winter, affected by the dry and cold air flow in the inland, the weather is cold, dry and rainy; Summer is affected by the warm and humid air flow from the ocean, which is hot, humid and rainy.
The high temperature period is consistent with the rainy period, and the water and heat match well, which is very beneficial to the growth of crops. The precipitation in the middle and lower reaches of the Yellow River in China is mainly concentrated in summer, which has the characteristics of "both rain and heat".
Climate elements mainly include temperature, precipitation and light. With abundant sunshine, abundant precipitation, high temperature, humidity, rain and heat, it is a superior climatic condition in the middle and lower reaches of the Yellow River in China, which is suitable for crop growth. Farming civilization was born here, and the 24 solar terms also originated here.
