Multi-span GreenhouseIt Is An Advanced Agricultural Facility That Connects Multiple Independent Greenhouses Through Gutters (drainage Channels) To Form A Large-scale, Continuous Production Space. It Has Far Surpassed The Simple Concept Of Traditional Greenhouses And Evolved Into A Modern "plant Factory" That Integrates Environmental Control, Logistics Management, And Data Decision-making, Representing One Of The Highest Levels Of Facility Agriculture.
1、 Core Advantage: Why Choose A Multi Span Greenhouse?
Compared With Traditional Single Arch Greenhouses Or Solar Greenhouses, Multi Span Greenhouses Have Unparalleled Advantages In Large-scale Production:
Extremely High Land Utilization Rate: Due To The Removal Of Gaps Between Individual Greenhouses, The Land Utilization Rate Can Reach Over 90%, Making It Particularly Suitable For Large-scale And Intensive Commercial Production.
Strong Controllability Of Production Environment: The Internal Space Is Spacious And Unified, Making It Easy To Equip Various Advanced Environmental Control Equipment (such As Shading, Ventilation, Cooling, Heating, Supplementary Lighting, Etc.), Achieving Precise Control Of Environmental Factors Such As Temperature, Humidity, Light, CO ₂ Concentration, Etc., Creating The Most Suitable Growth Conditions For Crops.
Easy To Achieve Mechanization And Automation: The Large Space Provides A Place For Automation Equipment To Use. From Automatic Seeders And Transplanters To Automatic Sprinkler Trucks, Logistics Transport Vehicles, And Even Robotic Picking, It Can Significantly Reduce Labor Costs And Improve Production Efficiency.
Stable Production Performance: With Powerful Structural Design (strong Wind And Snow Resistance) And Advanced Environmental Control Capabilities, It Can Resist The Interference Of Adverse Weather Conditions And Achieve Annual, Stable, And Balanced Supply Of Agricultural Products.
Intelligent Management: As An Ideal Carrier Of Technologies Such As The Internet Of Things And Big Data, Multi Span Greenhouses Are Easy To Upgrade To Smart Agriculture Cloud Platforms, Enabling Remote Monitoring, Data Analysis, And Intelligent Decision-making.
2、 Main Structure And Covering Materials
The Structure Of A Connected Greenhouse Is The Cornerstone Of Its Stability.
Main Structure: Typically, Hot-dip Galvanized Steel Frame Is Used To Ensure Corrosion Resistance And Strength. The Key Components Include:
Column: The Main Load-bearing Component.
Tiangou: A Core Connecting Component Used For Both Drainage And As A Track And Load-bearing Beam For Equipment Installation (such As Shading Systems And Sprinkler Systems).
Arches And Trusses: Form The Greenhouse Roof To Ensure Overall Stability.
Covering Materials: Diverse Choices, Each With Its Own Characteristics:
Glass (Venlo Type Greenhouse): The Highest Transmittance, Extremely Long Service Life, And Beautiful Appearance. It Is The First Choice For High-end Planting (such As High Value-added Fruits And Vegetables, Flowers, And Seedling Research And Development).
Plastic Film: The Lowest Cost, Fast Construction Speed, But Relatively Low Service Life And Light Transmittance Retention Rate.
Polycarbonate Board (PC Polycarbonate Panel): It Combines The High Transparency Of Glass With The Lightweight And Impact Resistance Of Thin Films, And Has Excellent Insulation Performance, Making It A Cost-effective Choice.
