Food standard multi span prefab multi-span commercial greenhouse structure
Welcome to our factory !
Po film greenhouse introduction:
Poly film greenhouse is the most cost-effective greenhouse and welcomed by the users. The traditional tunnel roof design is simple but strong. The polythene film can diffuse the light to protect the crop from burning and aid the photosynthesis, but it needs to change every 3-5 years. In the winter, especially in China. Double layer film can be laid with a pump to inject the hot air, not only to prevent the dissipation of the heat, but also to stop the cold air going in. So the inside temperature is guaranteed in cold weather. Poly film greenhouse anti-fog and anti-drip design will decrease the chance of the suffering from the disease of the plants . The huge roof ventilation and side ventilation will reduce the heat and humidity to make a temperate environment.

PO film greenhouse advantages:
*Hot dip galvanized frame
*High quality covering material
*One stop service

Optional Systems 

1. Outside and Inside Shading System
 The Shading system can keep out redundant sunshine, preventing the plants from being burned in the greenhouse. And it can regulate the heat or reduce the cost for the operations.  



2. Cooling System and Heating System
 Cooling System: Our factory is specialized at the products of cooling pads and fans, usually used cooperatively. The cooling pads are installed on one side of the greenhouse, the exhaust fans, etc. The air-circulating fans are installed in the greenhouse. The exhaust fans eject the air from the greenhouse (The air-circulating fans promote the circulation of the air in the greenhouse), negative pressure formed in the greenhouse. The air enters the greenhouse through the cooling pads, resulting in the effects of cooling, moistening and air-dedusting.  


Heating System: Heating System of Greenhouse refers to a set of suitable heating facilities chosen to meet the heating demands, consisting of heating source, heat-radiating facilities, heat-transmitting facilities. The main accessories include furnace, transmission pipeline, circulating water, radiator and sorts of controlling or regulating valves, etc.  



3. Ventilation System

 The ventilation systems in our company consist of Roof Ventilation Systems and Side Ventilation Systems according to the difference of the installation position. The Roof Ventilation Systems include the Roof Track-Cross Ventilation System and Roof Row-Rack Ventilation System. The Side Ventilation System refers to the side Cooling-Pad Ventilation System. Moreover, we also supply the Roof or Side Plastic-Film Reeling Ventilation System (Manual or Electric). 


4. Seedbed System, irrigation systems and Electric Control System.

  Seedbed system: It includes fixed seedbed and mobile seedbed and can promote the utilization rate effectively of the greenhouse, usually up to about 85%.
  Hydroponic System: Itapplies the hydroponics, is characterized with water-saving, fertilizer-saving, labor-saving as well as great harvest and superior quality, etc.
  Control System: It is a kind of environmental automatic control system that is designed for the agricultural greenhouse, adjusting the inner environment of the greenhouse to the most suitable conditions.  




5. Irrigation and fertilization water treatment system with reasonable design improves absorption function of crops toward fertilizer. Meanwhile, it improves crop quality.
 It is especially suitable for the area with poor water quality and crop greenhouse which has high requirements for planting water quality.
The advanced treatment process is combined with greenhouse production process effectively.
