Characteristics Of Plastic Film Greenhouses For Lettuce Cultivation

low cost
Plastic film materials are relatively inexpensive, and greenhouse frames can be made from bamboo, wood, steel, or plastic pipes, resulting in significantly lower construction costs compared to glass greenhouses or smart greenhouses. This makes them suitable for large-scale cultivation and small to medium-sized growers.
Easy to set up
The structure is simple, requiring no complex construction, and can be quickly assembled and disassembled, adapting to various terrains and planting sites, making it suitable for temporary planting or seasonal production.
Good light transmittance
Plastic film has high light transmittance, ensuring sufficient light for lettuce growth, promoting photosynthesis, and facilitating leaf development and quality improvement.
Moderate thermal insulation performance
Plastic film has a certain heat retention effect, which can reduce heat loss and help maintain relatively stable temperatures inside the greenhouse during winter or in low-temperature environments, making it suitable for the cool-loving growth characteristics of lettuce (optimal temperature range: 15-20°C).
rainproof and windproof
It can effectively block rain and strong winds, providing a relatively stable environment for lettuce growth and reducing the impact of natural disasters on crops.
High space utilization
It can be designed as an arched or gable structure with an open interior space, facilitating mechanized operations and cultivation management, making it suitable for high-density lettuce planting.
Environmental controllability is limited
Compared to smart greenhouses, plastic film greenhouses have weaker control capabilities for environmental parameters such as temperature, humidity, and light, requiring reliance on natural ventilation, shade nets, or simple heating equipment for regulation.
Low maintenance cost
The plastic film is easy to replace, with a simple skeletal structure. Daily maintenance primarily involves repairing film damage and cleaning ventilation openings, resulting in lower maintenance costs.
