The slight cold solar term is a slight cold when the sun reaches 285 degrees every year1October 5 or 6, and it is a solar term indicating the temperature change, just like the great cold, slight summer heat, great summer heat and summer heat. "Twenty-four solar terms": "December solar terms, the first cold is still small, so the cloud. It will be big in half a month. " A slight cold means that the weather is already very cold. The periods of slight cold and severe cold in most parts of China are generally the coldest. As soon as the "slight cold" passes, it will take three or nine days to "get out of the ice". In ancient China, slight cold was divided into three stages: "The first stage is to wait for Yanbei Township, the second stage is to wait for magpies to nest, and the third stage is to wait for pheasants to swim". The ancients believed that the geese among migratory birds migrated along the yin and yang, and at this time, the yang had moved, so the geese began to move northward; At this time, magpies can be seen everywhere in the north, feeling the yang and starting to build nests; The third time, the word "pheasant" means singing. When the pheasant approaches April 9, it will feel the growth of Yang and sing. At this time, the average temperature in Beijing is generally around -5℃, and the extreme minimum temperature is below-15℃. In Northeast China, the average temperature at this time is around -30℃, the extreme minimum temperature can be as low as -50℃, and the average maximum temperature in the afternoon is only -20℃. It's a world of ice sculptures and jade carvings. The average temperature in Heilongjiang, Inner Mongolia, the area north of 45 N in Xinjiang, the northern part of Qinghai-Tibet Plateau is around -20℃, and the average temperature in the area near 40 N west of Hetao is around-10℃, which is a scene of severe winter. The average temperature along the Huaihe River in Qinling Mountains is about 0℃, and there is no seasonal frozen soil in the south of this line, and there is no obvious wintering period for winter crops. At this time, the average temperature in the south of the Yangtze River is generally around 5℃. Although the field is still full of vitality, cold air sometimes goes south, causing certain harm. In the slight cold season, winter fertilizer should be applied to wheat, rape and other crops, but in Hainan and most parts of South China, it is mainly to prevent cold and frost, store fertilizer and build water conservancy projects. Artificial mulching is also an important measure to prevent freezing injury of agricultural and forestry crops in winter on the basis of pouring frozen water before winter, applying sufficient winter fertilizer and raising soil and rooting. When the cold air becomes stronger in the cold wave, the harm of low temperature to rape can be effectively reduced by pouring dilute manure and evacuating plant ash. Vegetable fields cultivated in the open field can be sparsely spread on vegetable beds as long-term winter plastic film, which will not affect the light, reduce the wind speed between vegetable plants, block the loss of geothermal energy, and play the role of heat preservation and antifreeze. When the low temperature comes, the covering will be thickened for temporary covering, and then removed in time after the low temperature. At this time, the vegetables in the greenhouse should get as much sunshine as possible. Even if there is rain, snow and cold weather, the grass curtain and other mulch outside the greenhouse should not be left uncovered for many days, so as not to affect the normal photosynthesis of plants and cause nutrient deficiency. If the curtain is opened on a sunny day, the plants will wither and die. Alpine tea gardens, especially those vulnerable to the northwest cold wind, should be covered with straw, weeds or plastic film to prevent the direct damage of dead branches and sandstorms caused by exhaust. After snowfall, the snow on the fruit branches should be shaken off as soon as possible to avoid the strong wind blowing off the branches. Calculation of the date of slight cold [Y * D+C]-Interpretation of the L formula: Y= two digits after the number of years, D=0.2422, L= leap year, 2 1 century C=5.4055, 20th century =6. 1 1. For example, the date of slight cold in 1988 = [88× .0.2422+6.11]-[(88-1)/4] = 27-21= 6. Exceptions: 1982 plus 1 day, 20 19 minus 1 day. [Edit this paragraph] Slight cold proverbs It doesn't snow, the fields in summer summer are cracked, it's freezing, and the Qingming quagmire is cold and cold. It will be cold and warm next spring. As the saying goes, "it's cold for three or nine days", and the degree of its cold can be imagined. Popular meteorological proverbs can be used as evidence. For example, in northern China, there is a saying that "slight cold and severe cold, dripping into ice", and in southern China, there is a saying that "slight cold and severe cold, dripping into ice". Although the severe cold and slight cold are cold every year, the cold situation is different. In some years, the slight cold is not very cold, which often indicates that the great cold is going to be cold. People in Guangxi have a proverb that "a slight cold is not cold, but a great cold is great". There are many proverbs that predict the future weather according to the cold and warm conditions of slight cold. Such as "it's hot in a slight cold day, cold in a severe cold day", "it's not cold in a slight cold day, it's clear and turbid", "it's cold in a severe cold day, it's warm in spring in the coming year", "it's warm in a slight cold day, it's snowy in beginning of spring", "it's cold in a slight cold day, it's warm in shock" and so on. According to the rainy (snowy) situation of the slight cold solar term, there are proverbs to predict the future weather: "Slight cold and rainy, rain still freezes seedlings" and "Slight cold and rainy, rain scares the seedlings to death". The masses have summed up the corresponding relationship between slight cold and severe cold and slight summer heat in many years' practice. For example, in Hunan province, "it doesn't snow in a slight cold, and the fields crack in a small summer", and in Shandong province, "it doesn't rain in a slight cold, but it will dry in a small summer".
