Introduction of 6 common types of agricultural greenhouses

The glass multi-span greenhouse adopts a hot-dip galvanized steel structure frame, and the covering material is generally 4-5mm high-quality float glass or tempered glass, with a light transmittance greater than 95%, and the top and surroundings of the greenhouse are special aluminum profiles for glass fixing. Most of these greenhouses have a spire structure, mainly Venlo type and large spire type. The glass multi-span greenhouse has the advantages of beautiful appearance, good light transmission, good display effect and long service life. The top window of the greenhouse is driven by a rack and pinion, and the ventilation rate can reach 27%. According to user needs, two ends of the greenhouse can be installed with wet curtains and fans, and aluminum sliding windows, casement windows or sides can also be installed on both ends and sides. Turn the window.

The winter warm steel frame greenhouse uses a steel frame instead of a large number of concrete pillars to support the face of the greenhouse, referred to as the columnless vegetable greenhouse. Strong compression resistance, large internal space, convenient for mechanical operation. The pillarless greenhouse can be used for breeding, seedling cultivation, flower planting, soilless cultivation, etc. If this kind of greenhouse is not considered damaged, the service life will be maintained at more than 20 years, and it will resist snowstorms and typhoons. Such greenhouse skeletons are all produced with galvanized strip steel shaping equipment, easy to install, no solder joints, beautiful appearance, corrosion resistance, strong structural strength and large load-bearing capacity. The service life is more than 15 years, and it is at the leading level in the domestic industry. .

The ecological greenhouse restaurant is a product of the perfect combination of modern facility agriculture and green catering. It is a large-scale greenhouse building that is people-oriented, catering as the mainstay, and landscape as the supplement. It combines the light, convenient and clear characteristics of the greenhouse with the multi-functionality of the building. Integrating into one, the restaurant has a green natural environment, "miniatures" and "artizes" the colorful ecological landscape of nature.

The top of the PC board smart greenhouse is covered with polycarbonate hollow board (PC board) or corrugated board. This material has light weight, good lighting, thermal insulation, anti-ultraviolet, anti-condensation, anti-icing and snow, high flame retardancy, anti-aging Good sex and other characteristics. This kind of greenhouse has beautiful appearance, good safety, strong drainage ability, large lighting area, uniform indoor illumination, moderate light transmittance, large span, and partitions can be conveniently set inside, which is beneficial to partition management and is suitable for flower planting and seedling breeding , Flower market, ecological hotel, scientific research, breeding and other purposes.

The simple multi-span arched greenhouse is a kind of greenhouse improved on the basis of the arched all-steel frame greenhouse. It is a new type of sunlight greenhouse between the arched greenhouse and the intelligent greenhouse. After this kind of greenhouse is covered with a double-layer film, thick gas can be formed, which can effectively prevent heat loss and prevent the intrusion of cold air, has good heat preservation effect, and has low operating costs in winter. The construction cost of the greenhouse is relatively low, and it is an economical greenhouse, which is suitable for most areas in my country.

The solar greenhouse uses the energy of the sun to increase the indoor temperature in the plastic greenhouse or glass house to meet the temperature requirements of plant growth, so people often call it an artificial greenhouse. The solar radiant heat of such greenhouses entering the greenhouse during the day often exceeds the heat that the greenhouse loses to the outside through various forms. At this time, the greenhouse is heating up. Sometimes due to the high temperature, some of the heat must be artificially released to adapt to plant growth. If a heat storage device is installed indoors, this excess heat can be stored.
