Greenhouse thermal-insulation wall

The utility model relates to the technical field of exterior wall thermal insulation, in particular to a greenhouse thermal-insulation wall. The greenhouse thermal-insulation wall comprises a foam cement thermal insulation plate body, an inner thermal insulation mortar layer and an outer thermal insulation mortar layer, wherein the inner thermal insulation mortar layer and the outer thermal insulation mortar layer are arranged on the inner side and the outer side of the foam cement thermal insulation plate body respectively, a delayed thermal insulation tube is arranged in the inner thermal insulation mortar layer, the inlet and the outlet of the delayed thermal insulation tube are each exposed of the outer surface of the inner thermal insulation mortar layer through an elbow, and the area of the plane, arranged on the inner thermal insulation mortar layer, of the delayed thermal insulation tube is at least 1/4 that of the plane of the inner thermal insulation mortar layer. The greenhouse thermal-insulation wall is simple in structure and low in cost, and a user can conveniently make the greenhouse thermal-insulation wall by himself or herself so that the production cost, the use cost and the management cost can be reduced. Besides, because the foam cement thermal insulation plate body can foam through various inorganic cementing materials such as silicious cement and magnesian cement, industrial solid waste can be used as filling materials, and the manufacturing cost is effectively reduced.
