Problems solved by technology

[0003] However, the structure of the general greenhouse is relatively simple, and its practical performance during use is obviously insufficient, and it does not have good heat preservation ability, and it cannot maintain a good ventilation effect while maintaining heat preservation. Not flexible enough during operation

Abstract

The invention relates to the technical field of two-film greenhouse structures and in particular relates to a two-film greenhouse back slope design and construction method. The two-film greenhouse structure comprises a foundation structure and a two-film control structure, wherein a greenhouse framework is arranged above the foundation structure; the two-film control structure is arranged above the greenhouse framework and comprises a shutter machine, waterproof heat insulation films, a heat insulation mat, a linkage column, a film rolling machine and a transparent shed film; the waterproof heat insulation films are arranged on the left and right sides of the film rolling machine; the film rolling machine is arranged above the shutter machine; the transparent shed film is arranged above the linkage column; and diversion structures are formed in the left and right sides of the two-film control structure. According to the two-film greenhouse back slope design and construction method, thecotton quilt is moved backwards by construction measures, so on one hand, the shading area is reduced compared with the traditional method, and illumination shot into the greenhouse is not blocked inthe scheme; on the other hand, the cotton quilt does not block front and rear ventilation openings so as not to form convection.

Description

technical field [0001] The invention relates to the technical field of double-film greenhouse structures, in particular to a method for designing and constructing the rear slope of a double-film greenhouse. Background technique [0002] With the production of high molecular polymers - polyvinyl chloride and polyethylene, plastic films are widely used in agriculture. In the early 1950s, Japan and European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. , my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used in small sheds to cover vegetables in Beijing, and achieved the effect of early maturity and increased production. Greenhouses were originally special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potte...
