It has the structural characteristics of a typical Wenluo style PC board greenhouse. Large space, strong load-bearing capacity, attractive appearance, easy to match with other facilities and equipment such as shading, supplementary lighting, sprinkler irrigation, etc.
Relatively lower cost, higher cost-effectiveness. The Wenluo type greenhouse covered with plastic film has much lower material and installation costs compared to greenhouses covered with PC boards or glass. Based on a construction scale of approximately 3000 square meters, including foundations, skeleton structures, covered doors and windows, internal shading systems, and control systems, the basic configuration of a greenhouse is calculated. If a Wenluo style PC board greenhouse is used, the construction unit price is about 400 yuan/m2. If a Wenluo style plastic film greenhouse is used, the cost of covering materials varies greatly, and the cross-sectional area of structural materials is smaller, resulting in lower installation labor costs. The construction unit price is about 300 yuan/m2. Compared to the cost saving of nearly 100 yuan per square meter, the cost-effectiveness is quite obvious.
Greenhouse functions are more targeted and have more uses. With the development of various functional films, choosing to cover these functional plastic films according to the growth needs of different crops can improve the quality of crops and increase the economic benefits for users. For example, using a scattering film, there is no shading indoors, and crop production is very uniform. Covering with Haige film can shade a portion of direct sunlight, and indoor shade tolerant plants can be planted, which can also serve as an office area. These proprietary features are difficult to achieve in a typical Wenluo style PC board greenhouse or glass greenhouse.
The greenhouse has better lighting performance. Covering with plastic film is cost-effective and can be replaced every 3 to 5 years. However, although PC boards or glass have a long service life, their lighting performance may not be as good as new plastic film due to dust accumulation, moss growth, and other reasons in the later stage.
Adopting a ridge track staggered outward swing window, compared to conventional roll film windows, it has higher ventilation efficiency, faster cooling, lower energy consumption, and is less prone to water leakage.
Using specialized aluminum alloy for the top and window frames, it is easy to tension the plastic film and can be equipped with insect proof nets and encrypted sealing strips, which have good insect proof, sealing, and insulation effects.
