Multi-Span Plastic Agriculture Hydroponics Greenhouse

Multi-Span plastic Agriculture Hydroponics Greenhouse

   Mutil span greenhouse is the upgrade product of single span greenhouse. This kind greenhouse  with bigger space and enhance the land utilization.  Many big agriculture machine can work in side. The kind greenhouse suitable for trees and flowers' planting. You can also add outer shading system, inner shading system,cooling system, heating system, irrigation system to make the best suitable greenhouse environment.

1.Technical list

2.Product advantage
Framework: All the steel pipe were after hot dip galvanized processing, with great corrosion resistance, so the service life is more than 20 years. You can customized the structure to make the high strength.
 
Film: The thickness of film is often chosen 0.12mm or 0.15mm. Generally speaking, it contains three coextrusion layers: drop layer, insulation layer and anti-age layer. The light transmittance can be up to 90%, and the service time is around 3-5 years. Besides, it has better insulation effect and high elasticity. 

1)Internal shading:Setting internal shading is an effective way to save energy, shade, temperature and humidity.The unique advantage of the  shading curtain is that it will reflect the sun rather than absorb sunlight, effectively reduce the greenhouse light, while reducing the temperature of crops and air.Unique thermal radiation barrier materials outside greenhouse emission, can keep the curtain under the heat is not lost.Close the sunshade curtain will increase the humidity indoor temperature rapidly.At the same time, sunshade of lower surface heat radiation transmitted from the greenhouse has good absorption ability, the curtain can maintain high temperature.High temperature curtain can prevent condensation, to avoid the condensed water surface under the curtain.
	2)Outside shading:In summer, the solar radiation heat load is too high,when the external shading system is used, the indoor temperature can be controlled to be only 1ºChigher than that of the outdoor room in a well ventilated greenhouse due to the blocking of most of the solar radiation into the greenhouse.If combined with wet curtain fan system, can create an ideal temperature and humidity environment, reduce greenhouse operation costs, saving energy consumption.
3)Exhust fan: Reasonable design, low noise, big air volume, strong wind, low operation cost;Air downstream synthetic type PVC blinds or aluminum shutters with oxidation resistance, light weight, deformation, flexible open, and it also can prevent air driven back ;High strength reinforced aluminum magnesium alloy belt pulley with light weight, high strength, good toughness, it has 6 pieces of stainless steel blade, it has no deformation, or fracture, it is also very attractive and durable;Configure high efficiency and energy saving motor through 3 c certification, protection grade: IP55, insulation class: F
	4)Cooling pad:Corrugated paper uses space cross-linking technology, which make it with high water absorption, high water resistant, mildew resistance, corrosion resistance, long service life.
5)Water treatment:Rare flowers and plants have very high request for its irrigation water. Bad quality can affect the growth of flowers and color beauty , and it also affect the flexibility of leaves and flowers which may  become fragile. For special irrigation water requirements for these rare flowers and plants, we have introduced international advanced water treatment technology, which can fully meet the requirements of irrigation water quality meeting to the standards of drinking water. We also can tailor the most appropriate water treatment system according to the customer's requirements.
	6)Sprinkler irrigation System:It use high-pressure pump for irrigation by spray system, which sprays water on the crops, is a method of irrigation water for the normal growth. It is a modern agricultural production technology collecting irrigation, fertilization and automation management. It can be divided into mobile pattern or sprinkler fixed irrigation system or half fixed spray irrigation system.
