The construction site is located in Juxian County, Rizhao City, Shandong Province, where a membrane-covered, multi-story greenhouse is being built.

Key Characteristics and Advantages

1. High Cost-Effectiveness
   This is the most significant advantage. Compared to glass or polycarbonate greenhouses, the initial investment and maintenance costs for a multi-span film greenhouse are substantially lower. The primary covering material, plastic film, is inexpensive and easy to replace, offering tremendous value for money.
2. Superior Space Utilization and Scalability
   By connecting multiple bays, these structures eliminate redundant side walls, creating a vast, uninterrupted interior space. This design allows for efficient use of land, facilitates the movement of large machinery, and enables highly streamlined,规模化 (scale-based) production operations.
3. Excellent Light Transmission and Insulation
   High-quality plastic films (such as PO or EVA films) can achieve light transmission rates of over 90%, ensuring crops receive ample sunlight. Furthermore, when designed with double-layer inflatable film walls, an effective layer of insulating air is created, which significantly improves heat retention and reduces energy consumption during colder months.
4. Effective Environmental Control Capabilities
   These greenhouses can be equipped with a comprehensive suite of systems to manage the internal climate, including:

· Ventilation Systems: Roof and side vents for natural air exchange.
· Shading Systems: Internal or external shade nets to control light intensity and temperature.
· Cooling Systems: Fan and pad systems for active evaporative cooling in hot weather.
· Heating Systems: Supplementary heating for year-round production.

5. Structural Durability
   Built with hot-dip galvanized steel frames, these greenhouses are designed to withstand specific wind and snow loads. The arched roof naturally promotes the runoff of rain and snow, minimizing the risk of structural damage.
