Heavy snow is the 21st solar term among the 24 solar terms, and the time is1February 7th or 8th every year in the Gregorian calendar, which is also the end of the month of the main branch calendar and the beginning of the next month. At that time, the sun will reach 255 degrees of the yellow meridian. Heavy snow means that the weather is colder, and the possibility of snowfall is greater than that of light snow. It does not mean that the amount of snowfall must be very large. On the contrary, the precipitation in various places has further decreased after heavy snow.
"Pickled vegetables with light snow, pickled meat with heavy snow" Every household is busy pickling "salted goods" as soon as the solar term of heavy snow arrives. Stir-fry salt with pepper, etc. in a pan. After the fried pepper salt is completely cooled, apply it to fish, meat and poultry, and knead it repeatedly until the color of the meat turns from fresh to dark, and liquid oozes from the surface. Then put the meat and the remaining salt into a jar, press it with stones, put it in a cool and backlit place, take it out half a month later, and hang it under the eaves of the rising sun to dry it to welcome the New Year.
People often say, "snow is good for a good year." Snow covers the earth in severe winter, which can keep the temperature around the ground and crops from falling very low because of the cold current, creating a good wintering environment for winter crops. When the snow melts, it increases the soil moisture content, which can meet the needs of crop growth in spring. In addition, the content of nitride in snow water is five times that of ordinary rain water, and it also plays a certain role in fertilizing fields. Therefore, there is an agricultural proverb that "this year, the wheat will be covered with three layers of quilts, and next year, the steamed bread will be used to sleep".
