Natural ventilation greenhouse

The invention discloses a natural ventilation greenhouse which comprises a concrete foundation, a main framework, walls and roofs. The natural ventilation greenhouse is characterized in that ridges are arranged on the roofs in the east-west direction, the roofs are connected in the south-north direction and the roofs are of asymmetric slope structures which are long in the southern sides and short in the northern sides. The ridge point southern roof is a lighting ventilation roof or a fixed lighting roof and the ridge point northern roof is a lighting ventilation roof. Vertical middle-suspension lighting windows are formed in the middle of the peripheral walls. Lighting boards are arranged on the upper portions of the peripheral walls. The natural ventilation greenhouse has the advantages of being capable of naturally regulating the environment along with season and weather changes, reducing investment of corresponding environment regulating facilities in construction of the greenhouse, reducing the environme
