heavy snow is an important solar term among the 24 solar terms in China, and it is the solar term after the light snow solar term in China. The weather has gradually become cold during the light snow. Is the heavy snow solar term cold in 2020? What are the heavy snow farming activities? Let's understand this solar term together with the old yellow calendar!

is the heavy snow solar term in 2020 cold: after the cold enters the "heavy snow" solar term, the cold air is active and the weather is getting colder and colder. Meteorological data show that during the heavy snow season, the average temperature in Northeast and Northwest China is below minus 10 ℃, and the temperature in the Yellow River Basin and North China is stable below 0 ℃. Cooling, snowfall, freezing rain, rime, haze and ice flood are several common weather characteristics after entering the "heavy snow". During the heavy snow season, except for the winter free areas in South China and southern Yunnan, most parts of China have entered winter. The cold air will have a very obvious cooling impact on the northern region. The cooling range from the central part of Inner Mongolia to the Huang Huai area is large, and the cooling in some areas may reach more than 10 ℃. The ancients said, "the big one is prosperous, and the snow is prosperous at this point". At this time, the snow often falls in a large and wide range, so it is called heavy snow. Like light snow, rain, grain rain and other solar terms, heavy snow is also a solar term that directly reflects precipitation. It indicates the starting time and amount of heavy snow during this period. In the season of heavy snow, the minimum temperature in most parts of China has dropped to 0 ℃ or below, and some areas may have heavy snow or even blizzard.

heavy snow solar terms farming activities in the north. There are few field management in the north, and winter wheat has stopped growing. It is a slack season, but farming activities still can not be relaxed. First of all, we should strengthen the management of winter wheat intercropping, hoe to preserve soil moisture, increase temperature and weed, and pay close attention to winter tillage while the ground is not firmly frozen. Snow covers the earth in severe winter, which can keep the temperature on the ground and around the crops from falling very low due to the invasion of cold current, creating a good overwintering 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 5 times that of ordinary rain water, and it also has a certain effect of fertilizing the field. If it doesn't snow in time, people occasionally pour frozen water once or twice when the weather gets a little warmer to improve the overwintering ability of wheat.

agricultural activities in the south. Wheat and rape are still growing slowly in the Yangtze Huaihe River and its south. We should pay attention to applying fertilizer well to lay a good foundation for safe overwintering and spring growth. When wheat in South China and southwest China enters the tillering stage, tiller fertilizer should be applied in combination with intertillage, and attention should be paid to ditch cleaning and drainage of winter crops. At this time, although the weather is cold, the stored vegetables and potatoes should be inspected diligently and ventilated in time. The cellar should not be closed too dead, so as to avoid high temperature rise and excessive humidity leading to rotten cellar. Keep the temperature as low as possible without freezing damage. Avoid no snow in heavy snow. If the snow is not timely, we must seize the opportunity and timely winter irrigation, so as to improve the overwintering ability of wheat. In heavy snow season, there are often weather disasters such as cooling, Blizzard, freezing rain, rime, flowing ice and so on. In case of freezing injury, loosen the soil and increase fertilizer in time, store water and raise temperature, strengthen the management in the middle and later stage, and strive to minimize the loss of freezing injury.
