Sunlight greenhouse with temperature control and stabilization functions

The utility model relates to a sunlight greenhouse with temperature control and stabilization functions. The sunlight greenhouse consists of a sunny roof, roof beams, a heat-preservation covering, a fixing rod, a rear roof, an upright post, a beam and combined profiles, wherein the beams, walls, the beam, a door and the upright post form a main body structure of the sunlight greenhouse; the sunny roof is fixedly arranged on the roof beams through purlines; the rear roof is fixedly arranged on the roof beams through purlines; the sunny roof is made from a transparent material; the rear roof and the walls are made from high-thermal resistance heat-preservation materials; the fixing rod is arranged above a joint of the sunny roof and the rear roof; one end of the heat-preservation covering is fixedly arranged on the fixing rod; the heat-preservation covering can be curled or uncurled, and when being uncurled, covers the sunny roof, and functions in reducing the daylighting area in the daytime and preserving heat at night; the temperature-selective combined profiles are arranged on the beam and the upright post, and are used for stabilizing temperature in the greenhouse; sunlight enters the sunlight greenhouse after penetrating through the sunny roof, and is converted into heat energy or used for the photosynthesis of crops. The sunlight greenhouse is novel in concept, attractive in structure, energy-saving and environment-friendly.
