The insulation wall 6 includes a heat absorption layer 61, a heat storage layer 62 and an insulation layer 63. The heat storage layer 62 is located in the middle, the heat absorption layer 61 is located on the side of the heat storage layer 62 close to the inside of the shed, and the insulation layer 63 is located on the side of the heat storage layer 62 close to the outside of the shed. When in use, the first scaffold 11 and the insulation wall 6 are arranged on the north side, and the heat absorption layer 61 is located on the southernmost side of the insulation wall 6 to absorb solar heat. In this embodiment, the heat absorption layer 61 adopts a mixture of coal and carbon black as raw materials, and the outer wall of the heat storage layer 62 is black to absorb light and fully absorb solar heat. During the day, the sun shines on the outer wall of the heat absorption layer 61 from the south (this embodiment is used in the area north of the Tropic of Cancer, and the sun shines from the south. If it is used in the southern hemisphere, the insulation wall 6 is set on the south), and the heat storage layer 62 is set in the middle. The heat storage layer 62 can adopt an aluminum storage box, and a heat storage layer 62 is arranged inside the heat storage layer 62. Medium, such as phase change heat storage material or sensible heat storage material. In this embodiment, sensible heat storage material, such as water, is selected. It has low cost and is easy to obtain. During the day, the heat absorption layer 61 absorbs heat and transfers it to the water inside through the aluminum wall of the heat storage layer 62. The aluminum wall conducts heat quickly. At night, when the temperature in the greenhouse is low, the water releases heat to keep the greenhouse warm as a whole, providing a good temperature environment for the growth of pomegranate seedlings in the greenhouse. The insulation layer 63 is arranged on the outside of the heat storage layer 62. The insulation layer 63 adopts existing insulation materials, such as insulation cotton and foamed polyurethane, to reduce the loss of heat from the heat storage layer 62.
