Multi-span GreenhouseIt Is A Large-scale Enclosed Planting Facility Formed By Connecting Multiple Single Greenhouses Through A Gutter. With The Core Advantages Of Scale, Intensification, And Controllable Environment, It Is Widely Used In Vegetable Planting, Flower Cultivation, Seedling Production, And Scientific Research. It Can Provide A Stable Growth Environment For Crops And Greatly Improve Planting Efficiency.
1、 Core Structure
Main Skeleton: Made Of Hot-dip Galvanized Steel Pipes Or Aluminum Alloys, Including Columns, Main Beams, Etc., With Column Spacing Of 4-8 Meters And Main Beam Span Of 8-12 Meters. It Is Wind And Snow Resistant (strengthened In The North And Optimized In The South), With A Lifespan Of 15-20 Years.
Covering Material: Glass With A Light Transmittance Of 85% -90% And A Lifespan Of Over 20 Years, Suitable For High-end Planting But With High Cost; Sunshine Board With A Light Transmittance Of 75% -85%, Lightweight And Impact Resistant, With A Lifespan Of 8-12 Years; Thin Film (EVA/PO Film) With A Light Transmittance Of 80% -85%, Low Cost, And A Lifespan Of 3-5 Years, Suitable For Economical Needs.
Environmental Control System:
Ventilation: Top Electric Window (opening 30 ° -45 °)+side Window, Equipped With Axial Flow Fan To Regulate Air;
Cooling: Wet Curtain Fan In Summer (cooling 5-8 ℃), High-end Shed With Spray;
Heating: In Winter In The North, Hot Water Or Hot Air Stoves Are Used To Heat The Greenhouse, Ensuring A Temperature Of ≥ 10 ℃;
Irrigation: Drip Irrigation/sprinkler Irrigation Integrated With Water And Fertilizer, Saving Water By 50% And Fertilizer By 30%;
Supplement Light: LED Plant Lights Cope With Insufficient Light And Prolong Photosynthesis.
2、 Core Advantages
High Space Utilization Rate: The Land Utilization Rate Is 80% -90% (traditional Single Building Only 60% -70%), Which Facilitates Mechanized Operations And Reduces Labor Costs.
Stable Environment: Large Enclosed Spaces Reduce External Fluctuations, With Smooth Temperature And Humidity Changes, Suitable For Sensitive Crops Such As Seedling Cultivation.
Convenient Management: The Central Control System Is Connected To Sensors To Monitor Temperature, Humidity, Lighting, Etc. In Real Time, Automatically Adjust Equipment, And Minimize Manual Intervention.
Strong Disaster Resistance: The Frame Is Stable, Resistant To Winds Above Level 10 And Snow Accumulation Of More Than 20cm, The Covering Material Is Impact Resistant, And Reduces Disaster Losses.
3、 Applicable Scenarios And Types
Scenario: Large Scale Planting (10000 Acres Of Vegetable/flower Base, Ensuring Consistent Quality); Seedling Cultivation (survival Rate ≥ 95%, Shortened Cycle); Scientific Research Exhibition (agricultural Scientific Research/popular Science Popularization In Tourist Parks).
Type: Wenluo Style (pointed Roof, Large Windows, Suitable For Rainy And Snowy Areas, Most Widely Used); Sunlight Type (insulation On One Side Of The Wall, Used In The North To Reduce Heating Costs); Thin Film Type (low Cost, Completed In 1-2 Months, Suitable For Short-term Planting).
4、 Maintenance Points
Structure: Regularly Check The Skeleton Bolts And Apply Anti Rust Paint Annually; Timely Repair/replace Damaged Covering Materials To Prevent Rainwater Damage To Equipment.
Equipment: Monthly Cleaning Curtain, Inspection Fan; Preventing Blockages In Seasonal Irrigation Pipes; Check For Pipeline Leaks Before Heating In Winter.
Environment: Regularly Calibrate Sensors, Close Windows And Reinforce Covering Materials Before Severe Weather.
Breaking Through Natural Limitations And Achieving Year-round Crop Production Through Connected Greenhouses Is The Mainstream Trend Of Efficient And Green Development In Large-scale Agriculture.
