The invention is suitable for the technical field of greenhouse structures, and provides a short back-wall and long back-slope sunlight greenhouse which comprises a greenhouse body, a roller blind, a long back-slope and a short back-wall, the greenhouse body is a light-transmitting arc-shaped slope surface, a front wall is arranged on the lower portion of the greenhouse body, a cold-proof layer is arranged on the exterior of the front wall, the roller blind is arranged on the vertex portion of the greenhouse body, a first upright and a second upright are arranged in the greenhouse body, the upper portion of the first upright is connected with the long back-slope in a supported mode, the lower portion of the first upright is connected with the bottom of the short back-wall, the upper portion of the second upright is connected with the vertex portion of the greenhouse body, the long back-slope is arranged between the short back-wall and the upper portion of the second upright, the long back-slope comprises a body, a heat-absorption layer is arranged on the inner surface of the body, a cement layer is arranged on the outer surface of the heat-absorption layer, plastic thin film, non-woven cloth and a heat-absorption layer are arranged on the outer surface of the long rear-slope from inside to outside in sequence, a slope of the second heat-absorption and the short back-wall are each provided with a soil layer, the height of the soil layer is the same as that of the vertex of the greenhouse body, the soil layers and the outer side of the short back-wall are each provided with the cold-proof layer. By means of the short back-wall and long back-slope sunlight greenhouse, heat can be absorbed rapidly, persistent heat dissipation can be achieved, and the heat preservation and the cold resistance can be achieved.
