The invention relates to an agricultural facility, in particular to an eggplant
solar greenhouse growing in an area north of
northern latitude 43 degrees in winter. The eggplant
solar greenhouse comprises a shed surface (1), a shed frame (2), upright posts (3), cross beams (4), a shed cover (6), a heat-insulating
blanket (7) and a heat-insulating wall (8). The eggplant
solar greenhouse is characterized in that: for the heat-insulating wall (8) of the solar
greenhouse, the bottom width d is 3,900-4,100mm, the upper width g is 2,450-2,550mm and the inside height f is 1,650-1,750mm; the span inside the shed b plus c is 5,400-5,600mm, the distance c between the upright posts (3) and the inside of the heat-insulating wall (8) is 1,080-1,120mm, the cross beams (4) are supported on the upright posts (3) and the total height e of the upright posts (3) and the cross beams (4) is 2,650-2,750mm; and the shed cover (6) is supported on the cross beams (4); and the inside elevation gamma of the shed cover (6) is 41-42 degrees. Compared with the traditional solar
greenhouse, structural parameters of the invention have large change, so that the invention remarkably improves the light-acceptance performance and the heat-insulating capability of the
greenhouse, provides adequate conditions for the growth of solanaceous fruit vegetables, in particular eggplants, achieves the goal of continuously producing the eggplants all year round by only depending on
sunlight heat source in the area north of
northern latitude 43 degrees in winter and remarkably improves the
economic benefits.
