What does it mean after the Spring Festival begins?

After the Spring Festival begins, it means that this solar term will be reached one day.

For example, the winter solstice is 65438+February 22nd, which means that 65438+February 22nd is the winter solstice season. The specific time of the 24 solar terms every year is uncertain and is calculated according to the solar cycle.

The term "solar terms" is not only commonly used in astronomy to indicate the change of solar terms, but also commonly used in China traditional culture. For example, in the traditional geomantic theory, when calculating numerology and marriage theory, there is a so-called "cross-knot month". In divination, it is considered that moving is not as good as static, and this change is a good thing, which may refer to the change at a specific time.

The origin of beginning of spring

Beginning of spring is one of the 24 solar terms, also called "beginning of spring", and "standing" means beginning. In China, beginning of spring is the beginning of spring, and every year on February 4th or 5th, when the sun reaches 365,438+05 degrees, it is beginning of spring. Among the 24 solar terms, the first month celebrates, stands and sets out, which is the same as the long summer, autumn and winter. Ancient Li Si refers to the beginning of spring, summer, autumn and winter, and its agricultural meaning means "planting in spring, growing in summer, harvesting in autumn and storing in winter", which summarizes the whole process of the relationship between agricultural production and climate in the middle and lower reaches of the Yellow River.

In climatology, spring refers to the period when the average temperature is 10℃ to 22℃ for five consecutive days. Speaking of beginning of spring, people obviously feel that the days are getting longer and the sun is getting warmer. Temperature, sunshine and rainfall are often at the turning point of the year and tend to rise or increase. The growth of crops in early spring is accelerated, and the water consumption for bolting rape and jointing wheat is increased. Irrigation and topdressing should be done in time to promote growth.
