In Greenhouse Cultivation, Light Is Not Only The Energy Source For Crop Photosynthesis, But Excessive Light Can Cause A Sudden Rise In Temperature Inside The Greenhouse, Burn Crop Leaves, And Even Affect Flowering And Fruiting. Sunshade Accessories, As A Key Component Of Greenhouse Environment Regulation, Can Accurately Balance Light And Temperature, Creating A Suitable Growth Environment For Crops, Especially In High Temperature Or Strong Light Areas In Summer. Their Role Is Irreplaceable. This Article Will Comprehensively AnalyzeGreenhouse Sunshade AccessoriesThe Core Values, Mainstream Types, And Practical Management Skills Of.
Core Function: Not Only Does It Provide Shade, But It Also Serves As A Comprehensive Environmental Regulator
Many Growers Believe That Sunshade Accessories Are Just "blocking The Sun", But In Fact, Their Functions Run Through The Entire Growth Cycle Of Crops, Achieving Multiple Regulatory Effects. The First Step Is To Cool Down And Protect The Seedlings. In Summer, Under Strong Sunlight At Noon, The Temperature In Unshielded Greenhouses Can Reach Over 40 ℃. High Quality Shading Accessories Can Block 50% -70% Of The Strong Light, Reducing The Temperature Inside The Greenhouse By 5-8 ℃ And Avoiding Vegetable Leaves And Flower Burns. Secondly, There Is Light Quality Optimization. Some Specialized Shading Nets Can Filter Harmful Ultraviolet Rays, Retain The Red And Blue Spectra That Are Conducive To Photosynthesis, And Improve Crop Quality. For Example, After Using Shading Accessories In Strawberry Cultivation, The Fruit Color Is More Uniform And The Sweetness Is Higher.
In Addition, Sunshade Accessories Can Also Reduce Water Evaporation. Under Strong Light, The Evaporation Rate Of Soil Moisture In The Greenhouse Will Accelerate By 30%. Sunshade Can Slow Down Evaporation, And Combined With Drip Irrigation Systems, It Can Significantly Save Water; In Severe Weather Such As Rainstorm And Hail, The Tough Shading Net Can Also Play A Protective Role To Reduce Crop Damage. For Seedling Cultivation Scenarios, Sun Shading Accessories Are Even More Essential, Providing Soft Light For Seedlings, Reducing The Risk Of Overgrowth, And Improving Seedling Success Rate.
Mainstream Type: Choose The Right "shading Solution" According To Your Needs
The Demand For Shading Varies Greatly Among Different Crops And Greenhouse Types. Currently, Shading Accessories On The Market Are Mainly Divided Into Two Categories: "shading Cover Materials" And "driving Control Equipment", Which Need To Be Used In Combination To Achieve The Best Effect.
Sunshade Covering Material: The Core Is "shading Rate" And "durability"
This Type Of Material Comes Into Direct Contact With Light, And Its Material And Shading Rate Determine The Shading Effect And Service Life, Which Is The Foundation Of Shading Systems.
1. Common Sunscreen: The Most Commonly Used Basic Model, Which Is Made Of Polyethylene (PE) And Polypropylene (PP). PE Is Anti-aging, Rain Resistant, And Has A Service Life Of 3-5 Years, Which Is The First Choice For Most Growers; PP Material Has A Lower Price, But Is Prone To Brittleness And Suitable For Short-term Use. According To The Shading Rate, It Can Be Divided Into Specifications Such As 30%, 50%, And 70%. Leafy Vegetables Require A Shading Rate Of 50% -60%, Melons And Fruits Require A Shading Rate Of 30% -40% During The Flowering And Fruiting Period, And High Shading Styles With A Shading Rate Of 70% Are Selected During The Seedling Stage.
2. Functional Sunshade: Designed For High-end Planting Scenarios, Such As Silver Gray Reflective Sunshade, It Not Only Blocks Light But Also Reflects Some Heat, With A Cooling Effect 20% Higher Than Ordinary Sunshade Nets; The Black And White Double-sided Sunshade Net Is Versatile, With The White Side Reflecting Strong Light And The Black Side Absorbing Heat, Making It Suitable For Switching Between Different Seasons. There Is Also An Internal Sunshade For Greenhouses, Which Is Installed On The Skeleton Inside The Greenhouse And Has Insulation Function. It Can Reduce Heat Loss When Folded In Winter, Achieving "winter Protection And Summer Shading".
3. Sunshade Film: Suitable For Glass Greenhouses Or PC Board Greenhouses, It Is Divided Into Diffuse Reflection Film And Diffuse Film, Which Can Convert Strong Light Into Soft Diffuse Light, Evenly Shining On Various Parts Of The Crop, Avoiding Insufficient Light On The Lower Leaves, Especially Suitable For High Seedling Crops Such As Tomatoes And Cucumbers. Its Transmittance Can Be Precisely Controlled, Generally Maintained At 50% -80%, And It Has Strong UV Resistance, With A Service Life Of Over 5 Years.
