1. Sunshade and Temperature Reduction: Covering in summer can effectively lower the temperature inside the shed by 3-8℃. By blocking 30%-70% of direct sunlight (with different shading rates available), it prevents crops from being burned by strong light or subjected to high temperature stress. The silver gray sunshade net has a shading rate of 35-45%, while the black net can reach 60-70%, significantly reducing the intensity of solar radiation. Technical Principle: The grid structure disperses sunlight energy, forming a buffer layer to lower the surface temperature by 8-14℃, while maintaining a suitable light intensity range for crop photosynthesis
2. Rain-blocking and Moisture-preserving: It can disperse over 85% of the impact force of rainstorms, reducing soil compaction; after coverage, air humidity can be increased by 13-17%, reducing soil evaporation. Application scenarios: It is commonly used in rainy regions of the south to prevent rainstorm scouring, and in the north during seedling cultivation to maintain soil moisture.
3. Windproof and disaster-resistant: It can reduce wind speed by 60%. When paired with aluminum alloy brackets, it can withstand Category 12 typhoons, protecting crops from extreme weather conditions. Special design: The aluminum foil composite material has a reflectivity of over 80%. In coastal areas, stainless steel accessories are required to enhance wind resistance.
4. Heat preservation and humidification: Covering in winter can increase the minimum temperature inside the shed by 1.4-5.1℃, preventing frost damage; covering at night can reduce heat loss.
