When is the heavy snow in 2023?
The solar term of heavy snow is 2 1 of the 24 solar terms and the third solar term in winter. The specific time is 65438+February 7th 17:32:44. The sun reaches the longitude of 255 degrees, and the intersection time is February 6-8 of the 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. The arrival of the solar term of heavy snow means that the weather will get colder and colder, and the possibility of snow will greatly increase. During heavy snow and solar terms, rivers in most parts of the north will freeze.
It is often said that "snow is good for harvest". In severe winter, snow covers the earth, so that the temperature around the ground and crops will not drop very low due to 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.
Brief introduction of agricultural activities in heavy snow and solar terms
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.
