Glass greenhouse construction and material selection: Large-scale multi-span glass greenhouses are one of the development trends of modern greenhouses. However, the increase in the single area will cause a certain difficulty in the construction design. The design needs to consider a variety of loads and adverse weather effects, and is a mechanical equipment 1. The entry and exit ports of the intelligent system must also rationalize the area of ​​the production area. The greenhouse designed and constructed after precision calculation can save energy for subsequent production and reduce operating costs.

Site selection: The selection of construction sites for large-scale multi-span glass greenhouses mainly considers the terrain and environmental constraints. In areas with seasonal winds in winter, try to choose to build greenhouses in areas with windshields such as mountains, windbreaks or tall buildings on the windward side. Comprehensive consideration is given to factors such as traffic, terrain height difference, energy, and landscape location, and of course the impact of natural disasters such as hail and earthquakes must be fully considered.

① Avoid basic farmland and general farmland as much as possible, and minimize the occupation of farmland by greenhouse construction.

②Choose as close to the heat source as possible, such as a thermal power plant, which can make full use of the hot water of the thermal power plant for heating to reduce its operating costs.

③ Choose as close to the main marketing area as possible to reduce storage and transportation costs.

④In the actual production of modern large-scale greenhouses and greenhouses, electricity is required. Therefore, issues such as power supply and line installation should be considered. We must strive for convenient access to electricity, simple routes, and to ensure power supply. Where conditions permit, two-way power supply equipment or some power generation facilities may be prepared for temporary emergency use.

⑤ Try to stay away from contaminated areas. If the soil, water and air in the greenhouse are contaminated, it will bring hidden dangers to crop production and affect consumer health. Therefore, try not to build greenhouses near polluting factories, especially the downwind of these factories or downstream of rivers.
