Insulation principle of greenhouse

        To know the the principle of heat preservation of greenhouse, let’s first look at the definition of the terms of greenhouse:       
        Greenhouses are agricultural construction facilities that use light-transmitting covering materials as all or part of the enclosure structure and have certain environmental control equipment to resist adverse weather conditions and ensure the normal growth and development of crops. The function of the greenhouse is to create environmental conditions suitable for the growth and development of crops and carry out effective production under the adversity of the natural environment.

          Principle of greenhouse heat preservation         solar radiation mainly short-wave radiation through the greenhouse After the material enters the greenhouse, the indoor ground temperature and air temperature increase and convert it into long-wave radiation. The long-wave radiation is blocked by the greenhouse covering material in the greenhouse, forming the accumulation of indoor heat from the two to increase the indoor temperature. This process is called “ The greenhouse effect”. Greenhouses use the "greenhouse effect" to increase the indoor temperature to create a suitable environment for crop growth in the cold season when crops are not suitable for open field growth to achieve the purpose of off-season crop production and increase crop yield.
       Simple point: heat absorption and heat preservation. On the one hand, the covering material of the greenhouse can absorb light and heat, and on the other hand, it also has the function of maintaining temperature and preventing heat loss.
      When you sleep in winter, hold a hot water bottle (solar radiation), and then cover a thick quilt (greenhouse film), it won't be cold!

        but with With the advancement of science and technology, greenhouse production has far exceeded the concept of "greenhouse effect". At present, the use of high-tech technology can automatically control various environmental factors in the greenhouse, including temperature, light, humidity, and CO2 fertilization. Control and regulation, according to the growth habits of the production crops and market needs, partly or completely get rid of the constraints of the natural environment, artificially create the best environment suitable for crop growth, and produce high-quality, high-yield products to meet different consumer groups Needs.
        
        Through our introduction above, you should understand the principle of heat preservation of greenhouse.
