Description

  The present invention relates to a heat steam utilization cultivation apparatus that is installed and used for cultivating various crops.

  Cultivation of crops using conventional thermal heating devices has mainly been heating systems that heat the inside of a house with heat, such as those that blow hot air with a boiler or the like, and those that are provided with an electric heater.

  However, many of these heating systems have a complicated structure, and many of them are difficult to install or have a high cost of installation. Heating was inefficient.

Also, when the cold was severe, frost fell into the ground, which could cause a difference in the planned harvest time. In addition, there was a risk of crop drying due to the heat and wind of the heating, and cultivation could fail.
