Multi-span GreenhouseThe Precise Regulation Capability Relies On The Collaborative Operation Of Eight Supporting Systems, Covering The Entire Chain Of Structural Support, Environmental Regulation, Water And Fertilizer Supply, And Intelligent Control.
Infrastructure System: The "Skeleton Foundation" Of Greenhouse
Composed Of Civil Foundation And Steel Frame, It Is A Prerequisite For The Stable Operation Of The Greenhouse. The Civil Foundation Needs To Be Designed According To Geological Conditions. In Northern Regions, The Impact Of Freezing Depth Should Be Considered, And Independent Foundations Or Strip Foundations Should Be Used; The Steel Frame Is Mostly Made Of Hot-dip Galvanized Material. After Anti-corrosion Treatment, The Frame Of The Corrugated Greenhouse Can Be Used For More Than 15 Years. The Connection Parts Are Fixed With Bolts To Ensure That The Overall Structure Is Stable And Undamaged Under 8 Level Wind And 30cm Snow Load. Some High-end Greenhouses Are Also Equipped With Aluminum Fittings For Sealing And Fixing The Covering Materials, Improving Overall Airtightness.
Environmental Control System: The 'Climate Steward' Of Crop Growth
As A Core Functional System, It Covers Multiple Subsystems Such As Ventilation, Shading, Heating, And Cooling, Achieving Full Cycle Environmental Optimization:
Ventilation System: Divided Into Two Categories: Natural Ventilation And Forced Ventilation. Natural Ventilation Is Achieved Through Electric Skylights And Side Windows, And The Skylight Design Of The Corrugated Greenhouse Can Increase Ventilation Efficiency By 25%; Forced Ventilation Is Combined With A Fan Wet Curtain System, Which Can Lower The Temperature Inside The Greenhouse By 5-8 ℃ During High Temperatures In Summer, Ensuring That Crops Are Protected From High Temperature Stress.
Sunshade And Insulation System: Adopting An Inner And Outer Double-layer Design - The Outer Layer Is A High Reflectivity Aluminum Foil Sunshade Curtain, Which Can Reflect More Than 60% Of Solar Radiation In Summer; The Inner Layer Is A Screen With Adjustable Light Transmittance, Which Can Reduce Heat Loss By 30% When Closed In Winter, Achieving Precise Temperature Control Throughout The Four Seasons.
Heating System: In Northern Regions, Water Or Air Heating Equipment Is Often Equipped To Evenly Transfer Heat To The Greenhouse Through Pipelines, And Automatic Start Stop Is Achieved With Temperature Sensors To Maintain A Stable Temperature Of Over 15 ℃ In The Greenhouse During Winter.
Planting Guarantee System: A High Yield And High Quality 'Nutrient Supply Line'
Including Irrigation And Seedbed Systems, Providing Precise Nourishment And Efficient Planting Conditions For Crop Growth:
Irrigation System: The Mainstream Adopts A Combination Of Mobile Sprinkler Irrigation And Drip Irrigation. The Mobile Sprinkler Irrigation System Is Installed On The Track Through A Suspension Rod, Which Can Achieve Cross Regional Operation Without Occupying Planting Space, And Is Suitable For The Foliar Water Replenishment Needs Of Wet Crops; Drip Irrigation Systems Can Directly Deliver Water And Fertilizer To Crop Roots, With A Water-saving And Fertilizer Saving Rate Of Over 60%.
Seedling Bed System: Composed Of Galvanized Steel Structure And Aluminum Alloy Frame, The Bed Net Is Woven With Anti-corrosion Treated Steel Wire, Equipped With Anti Overturning Limit Device, Which Can Flexibly Adjust Height And Spacing, Reduce Manual Operation Intensity, And Improve Seedling Efficiency And Survival Rate.
Intelligent Control System: Unmanned 'Neural Center'
Built On Internet Of Things Technology, It Consists Of A Sensing System, A Weather Station, An Intelligent Control Distribution Cabinet, And A Remote Platform. Indoor Sensors Collect Real-time Parameters Such As Temperature, Humidity, Light, Carbon Dioxide Concentration, Soil EC Value, And PH Value. Outdoor Meteorological Stations Synchronously Monitor Environmental Factors Such As Wind Direction, Wind Speed, And Ultraviolet Intensity. All Data Is Transmitted To The Control Cabinet And Cloud Platform Through RS485 Bus.
When The Measured Value Exceeds The Set Range, The System Can Automatically Trigger Control Actions: Such As When The Light Intensity Exceeds The Cucumber Light Saturation Point Of 55000 Lux, The Sunshade Will Automatically Unfold; When The Temperature Exceeds 30 ℃, The Fan And Sunroof Start Synchronously. Users Can Remotely View Data, Set Parameters, And Even Automatically Execute Scheduled Tasks Through Computers Or Mobile Terminals. For Example, A Fruit And Vegetable Planting Greenhouse In Fushun, Liaoning Has Achieved Unmanned Management From Seedling Cultivation To Harvesting Through This System.
