Multi-span GreenhouseIt Is Deeply Evolving Towards The Three Directions Of "intelligence, Energy Conservation, And Multifunctionality". At The Level Of Intelligent Control, The Application Of AI Algorithms Upgrades The System From "passive Response" To "active Prediction" - By Analyzing Crop Growth Cycle Data And Weather Forecasts, Shading, Irrigation, And Heating Strategies Can Be Pre-set 3 Days In Advance, Such As Automatically Maintaining A High Humidity Environment During The Seedling Stage And Increasing Ventilation During The Fruiting Stage To Promote Photosynthetic Efficiency.
In Terms Of Energy Utilization, The Combination Of Solar Photovoltaic Panels And Greenhouse Structures Has Become A New Trend. Installing Photovoltaic Panels On The Roof Of The Greenhouse Can Not Only Provide Power For The Greenhouse, But Also Achieve Natural Shading. Combined With Energy Storage Systems, It Can Reduce Traditional Energy Consumption By 60%. In Terms Of Material Innovation, The Development Of Biodegradable Films And Super Weather Resistant PC Boards Is Accelerating, Making Greenhouses More Environmentally Friendly And Durable.
In Terms Of Functional Expansion, Multi Span Greenhouses Are Shifting From A Single Production Space To A Composite Carrier Of "production+sightseeing+scientific Research": The Greenhouse Project In Youyu County, Shanxi Integrates Planting And Harvesting Functions, While The Project In Fushun, Liaoning Combines Planting And Experimental Purposes, Achieving A Dual Improvement In Economic And Social Benefits. In The Future, With The Application Of Digital Twin Technology, Virtual Models Of Greenhouses Can Be Constructed To Simulate And Optimize The Entire Process Of Environmental Regulation, Truly Creating A "predictable, Controllable, And Efficient" Modern Agricultural Intelligent Factory.
Selection And Operation: Scientific Rules For Long-term Operation
1. Three Elements Of Scientific Selection
Suitable For Regional Climate: In Cold And Snowy Northern Regions, PC Boards Or Glass Greenhouses Are Preferred, Paired With Reinforced Skeletons And Efficient Heating Systems; Thin Film Greenhouses Can Be Used In High-temperature And Rainy Areas In The South, With A Focus On Ventilation And Rainproof Design To Reduce Construction Costs.
Matching Planting Needs: High Value-added Crops Such As High-end Flowers And Medicinal Herbs Require The Use Of Glass Greenhouses With Intelligent Control Systems To Ensure Precise And Controllable Environmental Parameters; Ordinary Vegetable Cultivation Can Use Film Greenhouses, With Cost-effectiveness As The Core Consideration; For Sightseeing Agriculture Projects, Glass Greenhouses Are Preferred, Balancing Aesthetics And Functionality.
Balancing Cost-benefit: Short Term Projects Can Use Thin-film Greenhouses, Which Have Low Initial Investment And Fast Recovery; For Long-term Large-scale Projects, It Is Recommended To Choose PC Boards Or Glass Greenhouses. Although The Initial Investment Is Relatively High, The Comprehensive Operation And Maintenance Costs Over A 10-year Period Can Be Reduced By More Than 40%, Making It More Cost-effective.
2. Key Points Of Core Operation And Maintenance
Structural Maintenance: Check The Tightness Of The Skeleton Connection Bolts Every Month, Inspect The Corrosion Of Welding Points And Galvanized Layers Every Quarter, And Promptly Remove Rust And Apply Anti Rust Paint If Rust Is Found; Clean Up The Debris In The Gutter Before Winter Every Year, Ensuring That The Drainage Slope Is Not Less Than 3 ‰, To Prevent Damage To The Structure Caused By Snow And Water Accumulation.
System Maintenance: The Ventilation System Needs To Add Lubricating Oil To The Fans Every Quarter And Check For Damage And Blockage Of The Wet Curtains; Check The Tension Of The Sunshade System And The Temperature Of The Drive Motor Every Month. If It Exceeds 60 ℃, Stop The Machine Immediately For Troubleshooting; The Intelligent Sensor Is Calibrated With Standard Solution Every Six Months To Ensure That The Data Accuracy Error Does Not Exceed ± 2%.
Maintenance Of Covering Materials: The Holes In The Film Greenhouse Need To Be Repaired In A Timely Manner, And Special Film Covering Adhesive Should Be Used For Bonding. The Aging Film Pressing Line Should Be Replaced Every Year; PC Boards And Glass Greenhouses Need To Be Regularly Cleaned Of Surface Stains With A Soft Cloth To Avoid Scratches From Hard Objects That Affect Light Transmittance. The Sealant Should Be Replaced Promptly After Aging To Prevent Air And Water Leakage.
