The beginning of spring alias

Beginning of spring does not celebrate the Spring Festival, the first month, New Year's Day, New Year's Day, Spring Festival and so on.

1 beginning of spring began in the spring and autumn solar terms. Since the Qin Dynasty, China has always regarded beginning of spring as the beginning of the season in Meng Chun, and beginning of spring is the beginning of a year and silver moon in the official calendar. China's almanac and folklore all use "beginning of spring" as the basis for calculating the zodiac.

In early spring, the sun is located at 365,438+05 degrees of the yellow longitude, and the festival will be held on February 3-5. Since the spring, the temperature, sunshine and rainfall have increased. China is a vast country with a huge temperature difference between east, west, north and south. The middle and lower reaches of the Yellow River started from beginning of spring, and it has entered spring in chronological order.

But climatologically speaking, beginning of spring is just a prelude to spring, and 93% of China's land is still in the cold winter. Only some southern areas really enter spring, and most areas north of the Yellow River will not be able to welcome spring until April.

The origin of beginning of spring:

Twenty-four solar terms wrote: "beginning of spring, the fifteenth day of the first month. Standing, foundation and five elements of qi, the past has passed, and the new is still going on. Here, the spirit of Chunmu begins, so it is called standing, long summer, autumn and winter. "

Among them, beginning of spring is divided into three periods: first, when the east wind thaws, it means that the east wind warms and the earth begins to thaw; Second, the stinging insects begin to vibrate, which means that hibernating insects and beasts begin to wake up and creep; Three times a fish throws ice, which means that the ice in the river begins to melt and the fish begins to swim on the water.

In the ancient book "Family Tree", beginning of spring was interpreted as: "Career is also the foundation. Spring began and was established. " Since the Qin Dynasty, China has always regarded beginning of spring as the beginning of the Meng Chun season.

The greatest feature of beginning of spring's post-climate is that it is warm first and then cold, and the temperature begins to rise gradually. The temperature difference between day and night is large, the rainfall increases, the cold air activities are frequent, the cold spring occurs from time to time, and the windy weather in the north increases.

After beginning of spring, it is necessary to start plowing production, prepare seed fertilizer, trim farm tools, build water conservancy facilities, protect seedlings from freezing injury, and prune fruit trees. Winter wheat gradually turns green and jointing from south to north. In spring, it is necessary to prevent freezing injury, prevent diseases, pests and weeds, and carry out root promotion work.
