Agricultural Cooperative film greenhouse

Agricultural Cooperative film greenhouse is designed for agriculture vegetable and flowers, fruit planting, always with irrigation system and hydroponic system.

Agricultural Cooperative film greenhouse have multi span single layer greenhouse and multi span double layer film greenhouse like the following picture:

Agricultural cooperative film greenhouse specification:

1)  span 8m

2) section bay : 4m

3) column height 3m,4m

4) Ridge: 5m, 6m

the main steel structure column all are hot dip galvanized, covering material is PO film, 150 microns 200microns

Greenhouse film : 
 
The film referred to here is used for facility agricultural production and construction of special plastic film, economical and applicable, low cost, is one of the most common covering materials, there are four main: ethylene-vinyl acetate copolymer film, polyethylene (PE) film, dimming agricultural film, polyvinyl chloride (PVC) film.  The composition of these 4 materials is not the same, so the effect and characteristics of the use are also different.  
Ethylene-vinyl acetate copolymer film (EVA) is a new greenhouse covering material in recent years. It has good light transmittance, heat preservation effect, high yield, weather resistance and so on.  
Polyethylene (PE) film has the advantages of light weight, soft, easy modeling, good light transmittance, non-toxic, but it also has the disadvantages of not easy to bond, heat preservation effect and poor weather resistance.  According to the different components added in the PE film, it can also be divided into ordinary PE shed film, PE anti-aging film, PE anti-aging film without drops, PE insulation shed film, PE multi-functional composite film, etc.;  
Dimming agricultural film can selectively pass through light, make full use of solar energy, improve temperature and heat preservation, crop biochemical effect is strong, with early maturity, high quality and high yield and other functions.  
Polyvinyl chloride (PVC) film has the advantages of thermal insulation, light transmittance, good weather resistance, softness, easy modeling, as well as significant, the cost of the same coverage area increases, poor weather resistance, waste treatment is more troublesome and other disadvantages.  According to the different components added to PVC film can be divided into ordinary PVC shed film, PVC anti-aging film, PVC anti-aging film without drops (PVC double anti shed film), PVC weather resistance without drops dustproof film, etc..  

Agricultural cooperative film greenhouse Application:

At present, the continuous film greenhouse is mainly used in breeding seedlings, flower production, aquaculture, medicinal materials, edible fungi cultivation and other production greenhouse.  

Features:  
Large internal space, high wind and snow load, less light shielding, and hanging function, construction cost is relatively low.  

Structure:  
The main structure adopts hot-dip galvanized pipe, and the covering material adopts plastic film (the top adopts imported no-drop film, and the surrounding adopts imported long-life film).  
Service life of Agricultural cooperative film greenhouse 
 
10-20 years for main steel structure, 3-5 years for imported film.  

Configuration of Agricultural cooperative film greenhouse
 
It can be equipped with hot fan or water heating pipe heating system, fan forced ventilation system, internal and external sun shading system, micro fog or water curtain cooling system, spray/drip irrigation and fertilization system, CO2 supplement system, light supplement system and computer intelligent system.  

Serrated greenhouse each span one or two single slope, vertical window, even when it rains, can also open the skylight, compared with the ordinary round arch greenhouse, has better ventilation effect, better air flow, natural cooling effect is more obvious advantages, can better reduce the temperature and humidity in the greenhouse,  Especially suitable for the temperature and humidity through the natural environment regulation can meet the growth needs of the crop planting.  

High-matching terraced arch shed is an upgraded version of simple terraced greenhouse, which increases internal and external shading, wet curtain fan cooling, side window ventilation, temperature and heat preservation systems on the basis of simple type.  

Advantages: overcome the summer cooling and winter heat preservation, especially after increasing the double film, can effectively improve the winter greenhouse heat preservation effect, reduce the winter operation cost.  

Disadvantages: greenhouses cost relatively high, suitable for the use of high economic benefits of the industry;  Without the addition of double film, the winter insulation effect is relatively general.
