Every year on December 7th or 8th, when the sun's ecliptic longitude reaches 255 degrees, it is one of the twenty-four solar terms, "Heavy Snow". Heavy snow, as the name suggests, means heavy snowfall. The ancients said: "The big one is prosperous, and the snow is prosperous at this point." During this period, the snow often falls heavily and covers a wide area, hence the name heavy snow. At this time, the minimum temperature in most areas of our country has dropped to 0°C or below. Often in areas where warm and cold air meet at the front of strong cold air, heavy snowfall or even blizzards will occur. It can be seen that the heavy snow solar term refers to the starting time and snow amount of heavy snow during this period. It is the same solar term as light snow, rain, Guyu and other solar terms, which directly reflects precipitation. In ancient my country, heavy snow was divided into three periods: "In the first period, cuckoos and gulls do not cry; in the second period, tigers begin to make love; in the third period, heavy snow (1 photo) comes out." This means that due to the cold weather at this time, the cold trumpeting birds no longer Because this is the period when Yin Qi is at its peak, as the saying goes, it peaks and then declines, and Yang Qi has sprouted, so the tiger began to engage in courtship behavior; "Li Ting" is a kind of orchid, and it also feels the sprouting of Yang Qi And take out new shoots. People often say, "Auspicious snow heralds a good year." Snow covers the ground in severe winter, which can keep the temperature on the ground and around crops from falling too low due to cold waves, creating a good overwintering environment for winter crops. When the snow melts, it increases soil moisture content, which is needed for crop growth in the spring. In addition, the nitrogen content in snowwater is five times that of ordinary rainwater, and it also has a certain fertilizing effect. Therefore, there is a farmer's proverb: "This year, you will be covered with a three-layer wheat quilt, and next year you will sleep with a steamed bun on your pillow." During the heavy snow season, except for the winter-free areas of South China and southern Yunnan, the vast land of my country is covered with winter attire. The average temperature in the Northeast and Northwest regions has dropped to -10°C, and the temperature in the Yellow River Basin and North China has also stabilized below 0°C. In years with normal climate, snow has appeared in the Yellow River Basin and areas to the north, and winter wheat has stopped growing. After the heavy snowfall, the south of the Yangtze River enters the midwinter season. The temperature drops significantly in various places, and freezing phenomena often occur. "After the heavy snowfall in the winter solstice, the water in the basket does not leak" is a true portrayal of this time. However, this is not always the case in some years. The temperature is higher and there is no freezing phenomenon. , often causing heavy rain in the later period. Wheat and rapeseed are still growing slowly in the Jianghuai and south areas. Pay attention to applying wax fertilizer to lay a solid foundation for safe wintering and growth in the coming spring. As wheat in South China and Southwest China enters the tillering stage, tillering fertilizers should be applied in combination with cultivating, and attention should be paid to ditch clearing and drainage of winter crops. Although the weather is cold at this time, the stored vegetables and potatoes must be inspected frequently and ventilated in a timely manner. The cellar must not be closed too tightly to avoid excessive temperature rise and excessive humidity, which may lead to cellar rot. The temperature should be kept as low as possible without freezing damage. During the heavy snow season, people should pay attention to the meteorological station's forecasts of strong cold air and low temperatures, and pay attention to keeping warm and cold. Effective measures must be taken for overwintering crops to prevent freezing damage. Pay attention to keeping livestock protected from freezing and warm. The temperature drops significantly during heavy snowfall, and the geographical span between the north and the south is large, so the climate characteristics present in the north and south are different. The average temperature in most parts of the north has been below 0°C, especially in the middle and lower reaches of the Yellow River, where the water has frozen and snow has begun to accumulate. The average temperature in the south is generally between 8℃ and 9℃. Correspondingly, the farming life customs in the north and the south are also different. There is very little field management in the north. If the snow does not fall in time, people occasionally pour frozen water once or twice when the weather gets slightly warmer to improve the wheat's ability to survive the winter. Or repair poultry houses, livestock pen walls, etc. to help poultry and livestock survive the winter safely. As the saying goes, "It's a drought year when there's heavy snow, so don't waste time building ponds and building warehouses." At this time, work such as building waterways, accumulating manure, building warehouses, and warehousing grains in winter should be stepped up. The women gathered in small groups to do needlework. The craft house focuses on crafts, such as printing New Year pictures, grinding tofu, basket weaving, basket weaving, etc. to make money to support the family
