Sunlight greenhouse for winter vegetables in northern region

Abstract

The invention discloses a sunlight greenhouse for winter vegetables in the northern region. The sunlight greenhouse comprises a cold-proof layer, a front wall, a lighting roof, a greenhouse vertex, a rear roof, a loam wall, a quilt and an electric roller machine, wherein the direction of the sunlight greenhouse is 5-8 degrees toward the west; the span from the front wall to the loam wall is 7-9m; the roof lighting angles alpha corresponding to the places of 0.5-1.5m, 1.5-2.5m, 2.5-3.5m, 3.5-4.5m, 4.5-5.5m, 5.5-6.5m and 6.5-7.5m from the start point of the front wall in the greenhouse are 53-57 degrees, 48-52 degrees, 43-47 degrees, 38-42 degrees, 33-37 degrees, 28-32 degrees and 23-27 degrees respectively; the height from the greenhouse vertex to the indoor ground is 4.4-4.6m; the length of the inclined plane of the rear roof is 1.1-1.3m; the elevation angle between the top of the loam wall and the inner side of the roof in the greenhouse is 63-67 degrees; and a bottom angle of the loam wall in the greenhouse is 80-90 degrees.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a solar greenhouse for winter vegetables in the northern region. Background technique [0002] The solar greenhouse is an agricultural planting facility for growing vegetables in the cold season. Generally, vegetables are cultivated for overwintering without heating. Under the condition of no heating, the source of the temperature in the greenhouse mainly depends on the direct radiation and diffuse radiation of the sun, which shines through the film to the ground and Insulation walls, in turn, increase the indoor temperature, so the size of each part of the greenhouse must be designed according to the angle of altitude, latitude and sunlight, especially the size of the lighting surface angle of the greenhouse and the inward angle of the slope of the rear roof. Heat plays an important role. At present, the problem of heat preservation and heat storage in many solar greenhouses is mainly to us...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the problems existing in the above-mentioned products, and provides a winter vegetable solar greenhouse in the northern region, which solves the problem that the minimum temperature at night in winter in the northern region of my country is more than -20°. The design is unreasonable, which leads to certain limitations in the lighting and heat preservation capabilities of the greenhouse. Generally, only broad-leaved vegetables can be grown, and it is difficult to grow fruit-like vegetables such as tomatoes and peppers. Heating measures in the shed waste resources and increase workload, etc.
