Is the annual heavy snow 65438+February 7th?

Heavy snow is the third solar term in winter. Every year on February 7th or 8th of Gregorian calendar 12, when the sun moves to 255 degrees of the yellow longitude, it is called "heavy snow".

The heavy snow season is divided into three stages: "One stage is silent; Second, wait for the tiger to pay; Third, when you stand out. "That is to say, because of the cold weather at this time, the birds in Hao Han no longer sing; At this time, Yin Qi was in the heyday, and the so-called prosperity and decline, Yang Qi has sprouted, and tigers have begun to courtship; " "Liting" is a kind of bluegrass, which feels the germination of yang and sends out new buds.

People often say that "snow will bring a good harvest". In severe winter, snow covers the earth, so that the temperature around the ground and crops will not drop very low because of the cold current, and winter crops create a good wintering environment. When the snow melts, the soil moisture content is increased to meet the needs of crop growth in spring. The content of nitride in snow water is five times that of ordinary rain water, which has a certain effect on fertile fields. There is an agricultural proverb called "wheat covers three quilts this year and sleeps with steamed bread next year."
