The temperature regulation of the greenhouse is mainly carried out by ventilation and heating. The use of uncovered membranes for ventilation is the most common method for reducing and controlling the temperature in the shed during the day. The use of shading materials reduces the amount of light received in the greenhouse and prevents the temperature in the shed from becoming too high. In winter, in order to reduce heat loss and increase temperature and soil temperature, the shed film should be as tight as possible. Wind barriers can be installed around the greenhouses, and small sheds in the greenhouses can be covered with straw, non-woven fabrics, foam plastics (10540,155.00,1.49%) and other measures. Can also be used to increase temperature measures to increase temperature, such as the use of electric heating line to increase soil temperature, the conditions of the area can use the factory waste heat, geothermal water or coal furnace to improve the temperature inside the shed. The built-in waterproof bag (water-filled plastic bag) in the greenhouse uses characteristics that the water is hotter than the heat. During the day, the water bag absorbs a large amount of solar energy and is converted into heat energy to store it. It is gradually released at night and can increase the temperature of the greenhouse.
