Extended data
Heavy snow is 2 1 of the 24 solar terms and the third solar term in winter. When the sun reaches the longitude of 255 degrees, the node time is 65438+February 6-8 in Gregorian calendar every year. The solar term of heavy snow is the beginning of the second month of the dry calendar, marking the official start of the mid-winter season. Heavy snow is a solar term reflecting climate characteristics. Heavy snow solar terms are characterized by a significant drop in temperature and an increase in precipitation.
During the heavy snow, the national temperature dropped significantly, and the cold air in the north became more and more active. The heavy snow solar term is a climate concept, which represents the climate characteristics during the heavy snow solar term, that is, temperature and precipitation (water vapor condensate such as rain, snow and hail falling from the sky to the ground is called "precipitation" in meteorology). Like the light snow solar term, the heavy snow solar term is a solar term reflecting the changing trend of temperature and precipitation, and it is also a reflection of ancient farming culture on festivals.
rural activity
Agriculture is the foundation of the world. Farming refers to farm work, and farming time refers to farming opportunities. Doing farming according to the farming season will get twice the result with half the effort. Due to the great difference in climate characteristics between the north and the south of China, the main agricultural activities in the north and south are also different accordingly. In winter, the northern region is covered with snow, so it is almost impossible to grow crops. At this time, there is little field management in the northern region, which is the slack season.
Wheat, rape and other crops are still growing slowly in southern China, so it is very important to strengthen the field management of spring flowers. During the heavy snow season, meteorological disasters such as cooling, snowstorm, freezing rain, rime and drift often occur. If it is freezing injury, it is necessary to loosen the soil, increase fertilizer, store water and heat up in time, strengthen management in the middle and late stages, and strive to minimize the loss of freezing injury.
traditional custom
Bacon, snowball fights, snow scenery appreciation and tonic are all folk customs of heavy snow and solar terms. There is a saying in old Nanjing called "light snow pickles, heavy snow pickles". At this time, pickled meat, sausages, salted fish and other pickled products will be hung on the door and window sill of every household, forming a beautiful scenery. If it coincides with heavy snow, people will be keen on snowball fights and enjoy the snow scene in the ice and snow.
