Greenhouse Cover&Structure
- 1. Steel Structure
- Steel structure material is high quality carbon steel which is accordance with national standard. Steel parts and fasteners are processed according to “GB/T1912-2002 Technical Requirements and Test Methods of Hot-galvanized Layer for Metal Coating Steel Production”. Inside and outside hot galvanized steel should meet the national standard (GB/T3091-93) requirements of quality products. Galvanized layer should have thickness uniformity, no burr, and the galvanized layer thickness is not less than 60um.
- 2. Cover material
- The film cover usually uses PE film or PO film. PE film is produced by 3-layer technology, and PO film by 5-layer technology. All the film has UV coating, and it has characteristic of anti-drip and anti-aging.The film thickness is 120 microns, 150 microns or 200 microns.
Inner Sunshade&Warming System
This system is installing inner sunshade net in the greenhouse.In summer, it can reduce the inner temperature, and in winter and in night, it can prevent the heat running off. It has two types, ventilation type and thermal insulation type.
The internal thermal insulation curtain system is best suited for colder climates with temperatures below 5°C. Its main purpose is to reduce heat loss through infrared radiation on cold nights, thereby decreasing surface heat loss and cutting down the energy needed for heating. This can result in lower operating expenses for greenhouse facilities.
Cooling System
Cooling system can decrease the temperature according to the principle of evaporation of water for cooling. System has high-quality cooling pads and the fans with big wind.The core of cooling system is the cooling pads, which can evaporate water, is made of corrugated fiber paper.it is corrosion resistant and has long working life, because the raw material is added to a special chemical composition. The special cooling pads can ensure the water wets whole wall of cooling pads. When the air goes through the pads, the exchange of water and air on the surface of pads can change the hot air into cool air, then it can humidify and cool the air.
Ventilation System
Heating System
Heating system has two types, one type is using the boiler to provide heat, and another uses of electric. Boiler fuel can choose coal, oil, gas and bio fuels. Boilers need laying of pipelines and water warming blower to heat. If use electricity, you need electric warm air blower to heat.
Light Compensating System
Greenhouse compensating light, also known as plant light, is an essential source of artificial light used to support the growth and development of plants when natural sunlight is insufficient. This method aligns with the natural laws of plant growth and the concept of plants utilizing sunlight for photosynthesis. Currently, the majority of farmers utilize high pressure sodium lamps and LED lamps to provide this necessary light for their plants.
Irrigation System
We supply two types of irrigation system, drip irrigation system and spray irrigation system. So you can choose the best one for your greenhouse.
Nursery Bed System
Nursery bed has Fixed bed and movable bed. Movable nursery bed specifications: seedbed standard height 0.75m, can be adjustable a little. Standard width 1.65m, can be changed according to the width of the greenhouse, and length can be customized according to the user requirements; movable bed grid 130 mm x 30 mm (length x width), hot dip galvanized material, high corrosion resistance, good load-bearing capacity, long service life. Specifications for the fixed bed: length 16m, 1.4m wide, height 0.75m.
CO2 Control System
The main purpose is to achieve real-time monitoring of the CO2 concentration in the greenhouse, so that the CO2 in the greenhouse is always within the range of crops suitable for crop growth.Mainly including CO2 detector and CO2 generator. The CO2 sensor is a sensor used to detect CO2 concentration. It can monitor the environmental parameters in the greenhouse in real time and make adjustments based on the monitoring results to ensure a suitable growth environment for plants
