Automated intelligent Venlo-type greenhouse with a multi-layer PC board structure and a seedbed system

Introdution

The Venlo-type PC board greenhouse is a modular, gable-roofed structure characterized by its use of polycarbonate (PC) panels as the primary covering material. Its key features and advantages include:

• Light Performance: PC boards offer excellent light transmittance (80–90%) while diffusing sunlight evenly. This diffused light reduces the risk of leaf scorching, ensuring uniform growth across all crops, which is particularly beneficial for seedlings and leafy greens.

• Insulation & Energy Efficiency: Multi-layer PC panels provide superior thermal insulation compared to glass, minimizing heat loss in cold weather and reducing the need for excessive heating. This lowers energy consumption and operational costs.

• Durability & Safety: PC boards are shatter-resistant, lightweight, and highly resistant to impacts (e.g., hail, wind) and UV radiation, extending the greenhouse’s lifespan. Their lightweight nature also reduces structural stress, making the design easier to expand or modify.

• Cost-Effectiveness: Generally more affordable than glass in both material and installation costs, making it a practical choice for small to medium-scale operations or regions with harsh weather conditions.

Support systems

• Space Efficiency: Concentrate seedlings in a compact area, maximizing land use and simplifying monitoring and care.

• Reduced Pest/Disease Risk: Isolate young plants from soil-borne pathogens and pests, lowering infection chances compared to direct ground planting.

• Easy Transplantation: Seedlings grown in uniform beds develop stronger root systems, making them easier to uproot and transplant with minimal stress, improving survival rates.
