Sunlight board greenhouses are a replacement for traditional plastic film and glass greenhouses. They are mostly of the Venlo type (arch type is also available), mostly adopting a multi-span design. They feature a modern appearance, stable structure, beautiful and generous form, smooth visual effect, excellent insulation performance, moderate light transmittance, multiple gutters, large spans, large drainage capacity, and strong wind resistance. They are suitable for areas with relatively high wind and rainfall.

Structural Features

Connection MethodMultiple single greenhouses are connected through gutters and other components to form a continuous large greenhouse structure. This connection method makes the interior space of the greenhouse more spacious and open, facilitating large-scale agricultural production and mechanized operations.

Covering MaterialCommon covering materials include glass, sunlight boards, and plastic film. Glass has good light transmittance and is beautiful and durable; sunlight boards have strong insulation and high impact resistance; plastic film is relatively low in cost and easy to install, and can be selected according to different needs and crops.

Frame MaterialHot-dip galvanized steel pipes or aluminum alloys are mostly used, which have good strength and corrosion resistance, can withstand large wind and snow loads, and ensure the stability and safety of the greenhouse structure.

Performance Advantages

High Space Utilization RateThere are no or few internal columns, providing an open space with a large usable area. This allows growers to arrange planting and install equipment as needed. It is suitable for modern planting technologies and equipment, such as three-dimensional cultivation and soilless cultivation, improving land utilization and output.

Strong Environmental Control CapabilitiesEquipped with advanced environmental control systems, such as ventilation systems, shading systems, heating systems, cooling systems, and irrigation systems. Through the coordinated work of these systems, environmental parameters such as temperature, humidity, light, and carbon dioxide concentration inside the greenhouse can be precisely adjusted, creating suitable conditions for crop growth, achieving year-round production and high-quality yield.

Good Insulation PerformanceMostly using double-layer or multi-layer covering materials and good sealing measures to reduce heat loss and improve insulation. In winter, it can effectively reduce energy consumption and heating costs; in summer, through shading and ventilation measures, it can also achieve a good cooling effect, keeping the greenhouse temperature within the range suitable for crop growth.

Strong Disaster ResistanceThe overall structure is sturdy, and compared to single greenhouses, multi-span greenhouses have stronger wind and snow resistance. Its frame structure is carefully designed and calculated to withstand large external loads. In severe weather conditions, such as typhoons and blizzards, it can better protect crops and facilities.

Applications

Vegetable PlantingIt can be used to grow various vegetables, such as tomatoes, cucumbers, and peppers. Through precise environmental control, it achieves counter-seasonal production and year-round supply of vegetables, improving vegetable yield and quality to meet market demand.

Flower CultivationIt provides a suitable growth environment for flowers, beneficial to their growth and development, improving their quality and yield. It is often used for growing high-end flowers such as roses, lilies, and Phalaenopsis, meeting the needs of the flower market, and can also be used for flower research and seedling cultivation.

Fruit PlantingSome fruits with higher environmental requirements, such as strawberries and blueberries, can also be planted in multi-span greenhouses. By adjusting the temperature, humidity, and light conditions inside the greenhouse, it promotes fruit growth and maturation, improving fruit yield and quality, and can also extend the picking period.

Agricultural SightseeingWith its beautiful appearance and rich planting content, multi-span greenhouses are often used in agricultural sightseeing projects. They can be built into agricultural sightseeing parks, ecological restaurants, science and education bases, etc., attracting tourists to visit and experience the fun of agricultural production, while driving the development of local tourism and achieving organic integration of agriculture and tourism.

Covering Material

The top covering uses a UV-resistant outer layer and a dew-proof inner layer of polycarbonate hollow sheet. The surrounding walls are made of polycarbonate hollow sheet or glass according to conventional requirements. Depending on regional climate conditions, in some cold areas (Jilin, Heilongjiang, etc.), the north wall can use insulated composite panels, and sliding windows can also be installed to increase the greenhouse ventilation area.

Technical Parameters

Wind load resistance: 0.6KN/M2, 10 or greater wind; snow load resistance: 0.5 KN/M2; greenhouse constant load: 15KG/M2; maximum rainfall of the greenhouse: 140MM/h.

Main Configuration

Computer monitoring system, automatic control system, internal and external shading system, roof and side window system, evaporative cooling pad and fan cooling system, infrared heating system, etc.

Greenhouse Specification

The conventional specification of the greenhouse is a span of 9.6 meters or 12.8 meters, a bay width of 4 meters, an eave height of 4.2 meters, and a ridge height of 5.2 meters. The span and bay width can be adjusted according to user requirements.

Greenhouse Applications

This greenhouse is mainly used for ecological restaurants, display and sightseeing, scientific research experiments, demonstration and promotion, efficient planting (fruits, vegetables, flowers, trees, Chinese herbal medicines, etc.), agricultural product sales, efficient breeding (aquaculture, livestock, insects, etc.), and integrated industrial cycles.
