The role of the twenty-four solar terms in real life

Twenty-four solar terms are of great help to modern agriculture. With the popularization of meteorology, many areas have combined the 24 solar terms with agricultural meteorological data and compiled agricultural calendars and tables of agricultural activities, so that ancient experience can be combined with modern science and technology, learn from each other and complement each other, and play a role in modern agricultural production. The combination of these documents is based on the 24 solar terms.

Among them, the seasons in the 24 solar terms represent the change from cold to summer (four seasons): beginning of spring, vernal equinox, long summer, summer solstice, beginning of autumn, autumn equinox, beginning of winter and winter solstice; Symbolizing temperature changes: slight summer heat, great summer heat, intense heat, slight cold and severe cold; Reflect precipitation: rain, Grain Rain, white dew, cold dew, first frost, light snow and heavy snow; Reflect phenological phenomena or agricultural activities: shock, clear, small and full, awn seeds.

Twenty-four solar terms are a splendid culture created by working people in China, reflecting seasonal changes, guiding agricultural activities and affecting the food, clothing, housing and transportation of thousands of households.

The origin of the twenty-four solar terms

"Twenty-four solar terms" is the product of ancient farming civilization. It is a knowledge system formed by ancient ancestors following the farming season and observing the movement of celestial bodies to understand the changing laws of seasons, climate and phenology in a year. The twenty-four solar terms were originally formulated according to the changes of stars. The Big Dipper rotates in a circle and bucket handle rotates clockwise, which is called one of the "years".

The current "twenty-four solar terms" are formulated according to the position of the sun on the return to the ecliptic, that is, the annual movement track of the sun is divided into 24 equal parts, each 15 is 1, and each 1 is a solar term, starting in beginning of spring and ending in severe cold. ?

Through historical development, the lunar calendar absorbed the solar terms of the dry calendar as a supplement to the calendar, and adjusted it to conform to the tropic year through the leap method, forming a combined calendar of yin and yang, and the "twenty-four solar terms" became an important part of the lunar calendar. In the field of international meteorology, the 24 solar terms are known as "the fifth invention of China".
