Daming farmers use "geothermy" to warm up

Recently, at Fan Liying's home in Daming Street Village, the author saw that she was putting crushed cotton stalks, corn stalks, sawdust, and other wastes into the “deep hole”. I was puzzled by the fact that Fan Liying said: “It’s not winter, let’s put these things. It is by heating them for the winter. This geothermal heating method not only saves coal, but also makes full use of the straw, and the burned ash is still a good organic fertilizer."

It is understood that this "geothermal"

The heating is similar to that used in the past in rural areas, but it is much more practical and more scientific than designing a fire. The burning mouth is inside the house. The chimney is covered with thick soil outside the house. The smoke will not leak into the house and it is safe to use. Compared with traditional heating methods, floor heating adopts radiant heating, and heat loss is small during the entire transportation process, which greatly saves energy. At the same time, the floor heating uses low-temperature floor radiation to make people feel warm. According to statistics, more than 20% of farmers in Daming County have adopted this "geothermic" heating method.
