[0058] In addition, the greenhouse also has the necessary heat preservation cotton quilt, heat preservation film, electric window opening, etc. Because these are not the contents to be improved in the present application, they will not be described here.

[0059] The other five kinds of greenhouse are improved on the basis of the above-mentioned greenhouse. The specific structures of the remaining greenhouse can be clearly obtained by those skilled in the art in combination with the drawings and the components used. Among them, the north side of the heat storage dam type greenhouse is provided with a dam 28, and the first group and the fourth group of truss foundations are located on the dam 28, and the pendant 20 is embedded in the dam 28.

[0060] The present application has the following advantages:

[0061] 1. Each component is processed in the factory, with uniform size standards, and can be assembled into six different forms of greenhouse, to adapt to different agricultural planting projects in different regions: assembled light steel truss double-sided double-layer floor greenhouse, assembled light steel truss front double-layer back single-layer floor greenhouse, assembled light steel truss single-layer floor greenhouse, assembled light steel truss double-sided double-layer heat storage dam greenhouse, assembled light steel truss front double-layer back single-layer heat storage dam greenhouse, and assembled light steel truss single-layer heat storage dam greenhouse;

[0062] 2. Each component is standardized in the factory, with high component accuracy, and can produce complex components and high-quality corrosion-resistant treatment, with stable component quality and high production efficiency;

[0063] 3. The outer truss and the inner truss are reasonably divided into multiple components and are made by mechanical welding, with large structural stiffness, strong bearing capacity, simple corrosion-resistant treatment, convenient transportation, and the ability to adapt to various extreme weather conditions after construction;

[0064] 4. Each component can be connected and disassembled, making it extremely convenient to build and disassemble;

[0065] 5. The front and rear foundations are made of prefabricated reinforced concrete rods, which are easy to construct, do not damage the land, leave no fixed facilities after relocation, can be horizontally displaced during construction, effectively release the truss tension, and improve the structural strength;

[0066] 6. The front and rear landing points of each row of trusses are connected tightly by nylon ropes and buried stones, which effectively prevent the greenhouse from overturning and enhance stability. At the same time, the nylon ropes are always located under the planting soil and have no weathering risk, so they can be used for a long time without reducing the tension. Compared with steel fixtures, they are more reliable because steel fixtures are prone to rust when fixed under the soil;

[0067] 7. A set of horizontal transportation tracks can be installed with electric trolleys for material and product transportation, automatic pesticide spraying, and fertilization, meeting the requirements of modern agricultural production for mechanization and intelligent equipment development;

[0068] 8. The structure of the double-sided double-layer greenhouse supports each other, making the structure more reasonable and stronger, and providing complete implementation conditions for double-mode double-layer insulation. The insulation cotton can be placed between the double-layer structure and is not affected by rain, snow, and wind. The front and rear insulation cotton can be raised and lowered. The ventilation design can achieve front, rear, and upward ventilation, meeting the needs of various ventilation under different seasons and weather conditions. The lighting design allows the greenhouse to receive light from both north and south, adapting to the light of each season;

[0069] 9. The vertex position is reasonably moved to the south side of the whole greenhouse, which does not affect the front light, but also increases the light redundancy of the back greenhouse, and improves the slope of the front and back surfaces of the greenhouse, so that the accumulated snow cannot form accumulation on the surface of the greenhouse to cause collapse disaster, and improves the heat storage space in the greenhouse, and has better energy storage effect;

[0070] 10. The requirement of heat preservation and heat storage of the greenhouse in the severe cold area is fully considered, and the heat storage dam type greenhouse is specially used in the severe cold area.

[0071] Although the present application has been described in detail by the general description and specific embodiments above, some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the present application, all belong to the scope of the present application.
