[0002] In some high-latitude, high-altitude, mountainous areas, and cold areas with an average annual temperature below 0°C, greenhouses are usually used to grow vegetables and other crops in winter. However, since the outdoor temperature in cold areas is too low, general greenhouses need to be equipped with heating devices, such as stoves, radiators, heaters, and fuel heaters. Facilities and equipment, however, these heating devices consume a lot of energy, increase production costs, and also pollute the environment and crops. In addition, when it is particularly cold at night, there is a risk of crops in the greenhouse being frozen. Summary of the Invention

An underground insulation layer is filled in the greenhouse, and ground foundation beams are provided on three sides of the underground insulation layer. The left wall, the rear wall and the right wall connected in sequence are provided on the ground foundation beams. A plurality of supporting steel frames are evenly spaced between the left wall and the right wall, and a rear roof panel is fixedly mounted on the supporting steel frame and connected to the rear wall. A plurality of arc-shaped lighting steel trusses are evenly spaced in front of the rear roof panel, and the other end of the lighting steel truss is fixed to the ground on the other side of the underground insulation layer, and a greenhouse film is laid on the lighting steel truss. The left wall, the rear wall and the right wall are all sandwich insulation walls, and the inner side of the sandwich insulation wall is coated with a light-concentrating coating layer.
[0005] As a further improvement of the present invention, the underground insulation layer is composed of an extruded board layer, a backfill earth layer and a cultivated soil layer. The thickness of the extruded board layer is 50 to 70 mm, the thickness of the backfill earth layer is 650 to 750 mm, and the thickness of the cultivated soil layer is 200 to 500 mm.
[0006] As a further improvement of the present invention, the sandwich insulation wall is composed of a single-layer composite board on the outside and an extruded board on the inside, and rice husks or perlite are filled between the single-layer composite board and the extruded board; a steel wire mesh is provided on the outer surface of the extruded board, and a light-collecting coating layer is coated on the steel wire mesh, and the light-collecting coating layer is composed of a graphite powder heat-collecting mortar layer and an acrylic heat-absorbing coating layer.
[0007] As a further improvement of the present invention, the rear roof panel is composed of an inner color steel plate, an inner polystyrene plate, an outer polystyrene plate and an outer color steel plate, and a plurality of wooden strips are arranged between the inner polystyrene plate and the outer polystyrene plate to form a hollow layer between the inner polystyrene plate and the outer polystyrene plate, and the hollow layer is filled with rice husks or thermal insulation materials.
[0008] As a further improvement of the present invention, a thermal insulation blanket is installed on the upper end of the shed film at the connection between the lighting steel truss and the rear roof panel.
[0009] As a further improvement of the present invention, doors and windows are provided on the left wall or the right wall.
[0010] As a further improvement of the present invention, the skylight steel truss is formed by connecting more than one rack rods, and the downward inclination angle of adjacent rack rods is 15°.
[0011] The cold-region sunlight natural temperature-controlled greenhouse of the utility model has a reasonable structural design. The underground insulation layer can block the heat transfer in the ground, so that vegetables and fruits can be grown in the greenhouse in winter without heating, achieving zero energy consumption and zero emissions. The design of the sandwich insulation wall changes the original brick masonry structure of the sunlight greenhouse, which can block the heat release of the wall and achieve the insulation effect. The design of the rear roof panel can achieve the performance of no condensation on the roof of the greenhouse. The design of the concentrating coating layer can concentrate sunlight, convert sunlight into heat energy, and release heat in a direction to the front roof, which can quickly melt the frost on the greenhouse film, increase the temperature of the greenhouse, and store heat energy in the cultivated soil layer, so that the heat energy of the cultivated soil layer is increased, so that vegetables and fruits grown in the greenhouse under cold conditions can grow and develop normally.
