A kind of straw block solar greenhouse back wall

Abstract

The invention discloses a novel sunlight greenhouse rear wall made of straw blocks. The novel sunlight greenhouse rear wall made of straw blocks comprises a heat-accumulating layer, a heat-insulating layer and a heat preservation layer, and uprights are arranged on the two sides of the rear wall at equal intervals in the length direction of the rear wall; the heat-accumulating layer is isolated from the heat preservation layer through the heat-insulating layer, the heat-accumulating layer is formed by building straw blocks I, the heat preservation layer is formed by building straw blocks II, and the heat-insulating layer is formed by filling polystyrene boards; the outer side of the heat preservation layer is sequentially provided with iron gauze, clamping slots and plastic films; the straw blocks I are prepared from straw fibers, cement and sand according to the mass ratio of 1 to 6-9 to 15-24, and the straw blocks II are prepared from straw fibers and cement according to the mass ratio of 1 to 1.5-2.5. The novel sunlight greenhouse rear wall made of straw blocks composed of the straw blocks I, the polystyrene boards and the straw blocks II has the advantages of being strong in heat storage capacity, low in manufacturing cost, simple in construction technology, environmentally friendly, capable of fully utilizing rural surplus straw materials and the like, and the economic and ecological benefits of agricultural production can be effectively improved.

Description

technical field [0001] The invention relates to a back wall of a solar greenhouse, in particular to a back wall of a straw block solar greenhouse. Background technique [0002] The solar greenhouse is a unique type of greenhouse in my country. The back wall has the function of accumulating heat during the day and releasing heat at night, which plays an important role in the insulation of the greenhouse. The back wall of the existing solar greenhouse is mainly rammed earth wall, clay brick wall, etc. The rammed earth wall occupies a large area, the land utilization rate is not high, and destroys the cultivated land. Less heat, high thermal conductivity, large heat dissipation to the outside, resulting in low indoor temperature, high cost, and great environmental pollution. my country's annual production of straw is nearly 700 million tons, mainly including wheat straw, rice straw, cotton stalks, rape stalks, corn stalks, etc., which have not been effectively utilized, result...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of waste of resources and environmental pollution caused by a large amount of discarded straw in rural areas, use straw in the back wall of the solar greenhouse, improve the thermal insulation performance of the solar greenhouse, and realize the cost of the back wall of the solar greenhouse is low, more environmentally friendly, and the construction period is short. Effect, increase the economic benefits, ecological benefits and social benefits of solar greenhouses
