Single-Span Tunnel Greenhouse For Agriculture In Winter Vegetable Farming
Product Description
Arch Tunnel Type single-Span PE/Po Plastic Film Greenhouse for Commercial Farm
Unlike traditional tunnel greenhouses, the high tunnel greenhouse has a steeper vault design. This structural approach allows it to perform better in areas with heavy snowfall. Also, inside the high tunnel greenhouse, it has more space for completing various greenhouse systems inside. For example, internal shading, internal light shading, circulating fans, sprinkler irrigation, etc.

Frame Structure Materials
High -quality hot -dip galvanized steel structure, uses 20 years of service life.
All steel materials are assembled on the spot and do not require secondary treatment. Galvanized connectors and fasteners are not easy to rust.
Covering Materials
High transparency, Strong stretchability, Good insulation performance,anti-UV, Dust-proof and fog-proof, long life,Strong aesthetics
Ventilation System
According to the location of ventilation, the ventilation system of greenhouse is divided into, top ventilation and side ventilation. According to the different ways of opening windows, it is divided into rolled film ventilation and open window ventilation.
The temperature difference or wind pressure inside and outside the greenhouse is used to achieve air convection inside and outside the greenhouse to reduce the temperature and humidity inside.
The Exhaust Fan in the cooling system can be used for forced ventilation here.
According to the customer's demand, insect-proof net can be installed at the vent to prevent the entry of insects and birds.
Greenhouse Bench system System
The bench system of the greenhouse can be divided into rolling bench and fixed bench. The difference between them is whether there is a rotating pipe so that the seedbed table can move left and right. When using the rolling bench, it can better save the indoor space of the greenhouse and achieve a larger planting area, and its cost will increase accordingly. The hydroponic bench are equipped with an irrigation system that floods the crops in the beds. Or use a wire bench, which can greatly reduce the cost.
Mesh wire
Galvanized steel, excellent anti-corrosion performance
Outside frame
Aluminum alloy frame, anti-radiation, anti-rust, strong and durable
Lighting System
The greenhouse's supplemental light system has several advantages.
Suppressing short-day plants; promoting flowering of long-day plants. In addition, more light can extend the time of photosynthesis and accelerate plant growth.At the same time, the light position can be adjusted to achieve a better photosynthesis effect for the plant as a whole.
In cold environments, supplemental lighting can increase the temperature in the greenhouse to a certain extent.
Shading System
When the efficiency of shading reaches 100%, this type of greenhouse is called "blackout greenhouse" or "light dep greenhouse", and there is a special classification for this type of greenhouse.
It is distinguished by the location of the greenhouse shading system. The shading system of greenhouse is divided into external shading system and internal shading system.
The shading system in this case is to shade the strong light and reduce the intensity of light to achieve a suitable environment for plant production.
At the same time, the shading system can reduce the temperature inside the greenhouse to a certain extent. The external shading system provides some protection to the greenhouse in areas where hail is present.
Depending on the preparation material of shade netting, it is divided into round wire shade netting and flat wire shade netting. They have a shading rate of 10%-99%, or are customized.
Cooling System
Depending on the environment of the greenhouse location and the needs of the customer. We can use air conditioners or fan & cooling pad to cool the greenhouse.
Generally speaking, from the aspect of economy. We usually use a fan and a cooling pad together as a cooling system for the greenhouse.
The cooling effect is determined by the temperature of the local water source. In the water source greenhouse about 20 degrees, the internal temperature of the greenhouse can be reduced to about 25 degrees.
