Brief introduction of heavy snow in the twenty-four solar terms

Heavy snow is the 2nd1solar term in the twenty-four solar terms of the China lunar calendar, which generally appears on or around February 7th, 65438 in Gregorian calendar. It marks the gradual increase of snow and the official start of winter. The origin of heavy snow solar terms is mainly related to climate and agriculture.

The origin of the word heavy snow comes from ancient astronomical observation and description of natural phenomena. In ancient astronomy in China, when the sun passed 240 degrees east longitude, that is, from 240 degrees to 255 degrees longitude, it entered the solar term of heavy snow. The word "heavy snow" means that the cloud conditions, humidity and temperature conditions in the sky have gradually formed a large-scale snowfall environment.

The arrival of the solar term of heavy snow means that the transportation, life and agriculture in the northern region will be affected by snowfall. At this time, the temperature dropped, the cold air went south, and the moisture and humidity on the ground began to condense into snow, causing snowflakes to fly and the world to become silvery white. During heavy snow, people need to keep warm, pay attention to traffic safety, and take warm measures for farmland coverage to ensure the smooth growth of crops.

Agricultural activities:

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.
