The utility model discloses a semi-embedded natural warming and thermal insulation seedling culture greenhouse. The seedling culture greenhouse comprises stand columns, a ceiling and door walls. The two rows of stand columns are correspondingly arranged underground, the depth, embedded in the ground, of the stand columns on one side is larger than the depth, embedded in the ground, of the stand columns on the other side, and the height, exposed out of the ground, of the stand columns on one side is larger than the height, exposed out of the ground, of the stand columns on the other side. The ceiling is arranged across the stand columns on the two sides to form an inclined structure, a thermal insulation film is laid on the ceiling, and a thermal insulation blanket is laid on the thermal insulation film. The door walls are arranged at the two ends of a seedling culture greenhouse body and provided with entrance and exit doors. The seedling culture greenhouse is mainly used for seedling culture for tobacco production of tobacco-growing areas low in air temperature and poor in illumination. The semi-embedded natural warming and thermal insulation seedling culture greenhouse is designed to be a semicircular arc vault inclined wall type single-span film greenhouse. The framework of the greenhouse is made of light hot galvanizing sections, and a natural ventilation form is adopted. The internal temperature, the relative humidity and the like of the greenhouse are controlled through modern means, so that an appropriate growing environment is created for crops.
