On January 6th, it was a little cold, and it was not sunny to snow Whether snow indicates anything
There is an old saying that snow will fall in winter and rain in winter, what is this omen?What does the saying say?
Xiaohan is the 23rd of the 24 solar terms and the 5th in winter. This year's "Xiaohan" will be at 4:49:09 a.m. on January 6 this year, that is, on November 25 of the lunar calendar. "Little cold day" refers to the fact that the weather is very cold, but not the coldest season. The "small cold" is a season with lower temperatures, and there are only a few years when the temperature is lower than the "small cold". During the "Little Cold" period, severe winters have begun all over the country, the land is frozen, the rivers are frozen, and the cold current blowing from the north makes the climate very cold, which is called "the number of nine cold days". The southern part of China, although not as cold as the north, is also much lower than the north. In the south, the coldest time of the year is the period of light cold and after the rain to the sting. When it's cold, it's dry, and when it rains, it gets wet.
During the "small cold" period, the changes in temperature and rainfall of the "small cold" often indicate the weather and agricultural production of the next year. As the old saying goes: "It is better to snow than sunny than sunny." That is to say, in a small cold day, a snow is good for agriculture and nature;If the weather is fine, it will not be good. What's the point of that?This can be done from the following perspectives**.
Light snow is good for the maintenance of soil moisture.
During the cold season, when there is snowfall, a layer of snow accumulates on the ground, which prevents the water vapor from steaming on the ground and keeps the land moist. So that the plant can fully absorb water in winter, improve cold resistance, so as to achieve the purpose of increasing yield. However, if there is a small cold weather and no snow, the water in the land will evaporate quickly, causing the land to lack water, and in winter, the crops will stop growing due to lack of water until they die. Therefore, in cold weather, light snow falls, which allows the moisture of the land to be conserved, so that the crops can grow normally in winter.
Snowfall on a cold day is good for soil improvement.
When it's cold, if it snows, snow will fall. The snow cover is usually more than 5 cm, which has the function of a certain thermal insulation and reducing the temperature of the ground. In this way, microorganisms and organic matter in the soil are continuously degraded, releasing nutrients such as N, P, K, etc., thus improving the fertility of the land. However, if the weather is sunny and there is no snow, the surface is blown by cold winds, the temperature plummets, and the content of microorganisms and organic matter in the soil is low, resulting in a decline in soil fertility. In addition, the cold wind will also blow off the fine-grained soil in the topsoil, causing uneven soil quality and causing soil damage. Therefore, during the winter snowfall, it is beneficial for both structural and fertilization of the soil.
Light snow helps to get rid of insects.
In the cold season, if there is snowfall, there is snow on the ground, which has a disinfection effect to remove some bacteria and insect eggs remaining in the farmland, so as to reduce the pests and diseases of the next year. However, if the ground is exposed to the sun on a cold day and there is no snow, certain bacteria and eggs can be warmed up, thereby increasing the incidence of pests and diseases in the coming year. Therefore, when heavy snow falls on a small cold day, it is beneficial for the removal of pests and pests, and it is beneficial for the growth of crops.
A light snowfall is helpful for the climate forecast for the coming year.
During the cold season, if there is snowfall, it means that the temperature is on the cold side, and the amount of cold air is high, which means that the spring and summer of the next year will be cooler, with more rainfall and better crops. Conversely, if the weather is sunny and there is no snow in the cold weather, it means that the temperature is higher and the cold air is less, which means that the spring and summer of the following year will be hotter, with less rain and a worse crop. Therefore, the appearance of "small cold days" is beneficial to the weather forecast and agricultural production in the coming year.
These are several signs and advantages of "small cold days", from which we can see that "small cold days" are beneficial to farming and nature, which is why the ancients said that "small cold should be snowy, not sunny". Of course, this is just my own personal experience, my own observation, and it is not 100% correct, but it also depends on the environment and environment at that time. Despite this, we can still see the respect and care of the ancient ancestors for nature, and their cherishing and love for farming. When it is cold, we can also step on the plum blossoms in the snow, appreciate the beauty of winter, and experience the taste of the year, but also do a good job of keeping warm and avoid catching a cold
