Greenhouse with sunny and shaded surfaces

Abstract

The invention discloses a greenhouse with sunny and shaded surfaces. The greenhouse with sunny and shaded surfaces comprises insulating layers, a front wall, a back wall, a daylighting roof, an earthen wall, a planting bed, a front shed ridge, a back shed, a back shed ridge, an air vent, roller shutters and motors. The greenhouse is in the east-west direction. The front portion of the front wall and the back portion of the back wall are the insulating layers. The daylighting roof is arranged between the top of the front wall and the top of the earthen wall as high as 3-4 meters. The step-shaped planting bed is arranged on the surface facing the shaded surface, the inner side elevation angle formed between the top of the earthen wall and the roof in the shed is 63-67 degrees, a bottom corner in the greenhouse is at 80-90 degrees, and the bottom as deep as 40-60 cm is level to the ground level. The daylighting roof and the back shed are composed of inner layers of steel tubes and outer layers of steel tubes covering ethylene vinyl acetate (EVA) long-life fog-dispersal dripping films respectively. The front shed ridge is as high as 6-7 meters, the back shed is arranged between the top of the earthen wall and the top of the back wall, the back shed ridge is as high as 5-6 meters, the distance between the front wall and the earthen wall is 13-17 meters, and the distance between the earthen wall and the back wall is 8-12 meters. The greenhouse with sunny and shaded surfaces improves the land utilization rate.

Description

technical field [0001] The invention relates to the field of solar greenhouses, in particular to a planting greenhouse with both yin and yang sides. Background technique [0002] At present, the structure of many solar greenhouses is that the front and rear walls are connected by an arch shed as the basic structure of the solar greenhouse. In order to save costs and have good thermal insulation performance, many rear walls are built with earth walls. The thickness of the earth wall is about 2-5 meters thick. Usually , The cost of building a solar greenhouse is often high. When the occupied land is large, the corresponding land use area is wasted, which is not conducive to increasing income. How to maximize the usable area under the limited construction cost has become an urgent problem for many greenhouse farmers to solve. The existing solar greenhouses mainly adopt east-west orientation, absorbing sunlight and increasing temperature through the lighting roof, and the shade ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problems of the above-mentioned products, and provides a planting greenhouse with both sides of yin and yang, which solves the problem that the existing solar greenhouses of the above-mentioned products mainly adopt east-west direction, absorb sunlight and increase temperature through the daylighting roof, and the shade behind the back wall is not fully utilized. At present, there is a kind of solar greenhouse where the yin and yang sides are planted together, but the shady side is simply planted with edible fungi, and the back wall is not modified, so that the back wall occupies a large area of ​​land, which is not conducive to saving land and other issues.
