The ground temperature is used to master the temperature of putting the starter into the pit and entering the kiln, and refers to the temperature of the thermometer set in contact with the ground at the ventilated and dry place in the brewing workshop. The ground temperature is one of the meteorological observation items and is a very useful climate resource. Shallow geothermal energy refers to the low-temperature heat energy stored in the soil, sand and gravel, and groundwater within hundreds of meters of the shallow surface of the earth. It widely exists in the constant temperature zone of the shallow surface layer, is less affected by the seasons of the year, and the soil temperature is relatively constant. Compared with deep geothermal energy, shallow geothermal energy is widely distributed, has huge reserves, regenerates rapidly, requires less investment in development and utilization, and has great value, meeting the requirements of the development of circular economy.
