Greenhouse is an agricultural facility, which is mainly used to provide a suitable growth environment in seasons that are not suitable for plant growth, and to increase the growth cycle and yield of plants. The structure and function of the greenhouse are as follows:
Structure

‌Skeleton structure‌: The skeleton structure of the greenhouse is usually made of high-quality steel, with a reasonable design, which not only ensures the overall stability, but also facilitates installation and maintenance.
‌Covering material‌: There are many options for covering materials for greenhouses, including glass, solar panels and plastic films. Glass greenhouses usually use high-strength tempered glass, which has good light transmittance and corrosion resistance; solar panel greenhouses have the characteristics of strong impact resistance and heat preservation; plastic film greenhouses are widely used because of their lightness and low cost.
‌Ventilation system‌: It includes natural ventilation and forced ventilation. Natural ventilation realizes air exchange by setting ventilation windows and using the principle of hot air rising and cold air sinking; forced ventilation uses equipment such as fans to speed up the air flow and adjust the temperature and humidity in the greenhouse.
‌Heating system‌: In cold seasons, greenhouses are usually equipped with heating equipment, such as heaters, hot air furnaces, etc., to ensure that the temperature in the greenhouse is suitable for plant growth.
Cooling system: In hot seasons, greenhouses need to be cooled. Common cooling methods include sunshade, wet curtain-fan cooling, etc. Sunshade can block some direct sunlight and reduce the temperature in the greenhouse; wet curtain-fan cooling uses the principle of water evaporation and heat absorption, and uses the fan to cool the hot air outside the greenhouse through the wet curtain and then send it into the greenhouse. Irrigation system: Provide precise irrigation services according to the needs of plants. Drip irrigation, sprinkler irrigation, etc. can be used to save water while ensuring that plants get sufficient water supply.
