Solar greenhouse without back wall

Abstract

The invention discloses a solar greenhouse without a back wall, which comprises a shed body, the shed body includes a rear slope heat preservation body and a front slope light-transmitting heat preservation body, the heat storage mound is arranged in the shed body, and the back slope The surface heat preservation body includes a waterproof plastic film, and the waterproof plastic film is covered with a non-woven fabric, and the surface of the non-woven fabric is poured with an outer protective slurry formed by mixing glue and mud; There is a heat-absorbing layer, which is formed by spraying glue and mud mixture, and the outer surface of the heat-absorbing layer is also provided with a cement layer; it can effectively maintain the normal growth temperature of vegetables at night, and the inner wall surface of the back slope insulation High strength, can effectively prevent moisture in the greenhouse from penetrating into the rear slope insulation body, and the rear slope insulation body has a good thermal insulation effect.

Description

technical field [0001] The invention relates to a solar greenhouse. Background technique [0002] Existing ordinary solar greenhouses mostly use excavated soil to build a solar greenhouse with a rear wall and a rear slope. The outstanding advantages of the rear wall and a rear slope solar greenhouse are: the rear wall not only has the function of cold insulation and heat preservation, but also has the function of energy storage. Heat storage function, during the day, part of the sunlight irradiates the back wall, which is converted into heat energy and stored in the earth wall. The temperature in the greenhouse at night will not be lower than the temperature to maintain the normal growth of vegetables. In the Jiangnan area with a high groundwater level, the grassland Gobi area and sandy soil area with a shallow soil layer, it is impossible to dig down the soil to build a back wall and back slope type solar greenhouse, while the insulation arch shed and the ordinary insulati...

Problems solved by technology

In the Jiangnan area with a high groundwater level, the grassland Gobi area and sandy soil area with a shallow soil layer, it is impossible to dig down the soil to build a back wall and back slope type solar greenhouse, while the insulation arch shed and the ordinary insulation back wall greenhouse, due to heat storage Poor thermal insulation performance, it is not possible to grow overwintering high-temperature vegetables in severe cold seasons
