Multi-Span Film Greenhouse
Optimized Multi-Span Film Greenhouse Solution: Precision Agriculture with Cost-Efficiency
(Designed for Crop Cultivation, Seedling Production, and Eco-Tourism)
Structural Design & Material Innovation
-
High-Strength Framework
- Modular Architecture: Standardized 8m span × 4m bay design with adjustable eave height (3-5m) and ridge height (5.2-5.7m), achieving 90%+ spatial efficiency.
- Anti-Corrosion Steel: Hot-dip galvanized Q235 rectangular steel (main columns: 100×50×2.0mm; arches: φ32×2.0mm) with ≥80μm zinc coating, supporting wind/snow loads up to 0.5kN/m² and 0.35kN/m².
- Dual-Layer Drainage: Curved roof design enhances rainwater runoff, paired with 2.0mm cold-bent galvanized gutters (140mm/hr drainage capacity).
-
Advanced Cladding Materials
- Top Cover: Optional 12-15μm PO film (85%+ light transmission, anti-condensation) or 8mm polycarbonate (PC) hollow sheets (89% transparency, 200x impact resistance of glass).
- Sidewalls: Customizable with double-layer inflatable film (40% better insulation) or PC panels for northern climates.
Smart Environmental Control Systems
-
Climate Management
- Cooling: Cross-ventilation via east-side exhaust fans + west-side wet pads (5-8°C temperature drop).
- Heating: Integrated gas/electric systems with natural ventilation through roll-up side films.
- Light Optimization: Adjustable 65-85% shading nets + inner thermal screens; optional LED grow lights (PAR ≥200μmol/m²/s).
-
IoT-Driven Automation
- Real-Time Monitoring: Sensors track air/soil temperature, humidity, CO₂, and light intensity, syncing with actuators (shading, irrigation, ventilation).
- Remote Control: Mobile app access for data analytics, crop growth modeling, and disease alerts.
Key Applications & Flexibility
-
Agricultural Production
- High-Yield Farming: Ideal for tomatoes (20,000 kg/acre), dwarf fruit trees, and mushrooms via movable tidal seedling beds (50kg/m² load capacity).
- Seedling Cultivation: 20% higher germination rates with precise microclimate control.
-
Multi-Functional Expansion
- Eco-Tourism: Adaptable for agritourism (e.g., educational centers, farm-to-table restaurants).
- Research & Breeding: Supports hydroponics, tissue culture labs, and variable isolation trials.
Cost-Effectiveness & ROI
- Budget-Friendly: Construction costs 220-300 RMB/m² (1/3 of glass greenhouses) with 40-57% energy savings.
- Durability: 25+ year lifespan; annual maintenance <5 RMB/m².
- Scalability: Modular design allows rapid expansion; ROI within 3-5 years
