Introduction
Plastic film greenhouses are an increasingly popular technology for protected cultivation around the world. China plastic film greenhouse manufacturer is the leading manufacturer. This article provides an in-depth look at China’s major manufacturers, their innovative products, and the advantages of using plastic film greenhouses.
Introduction to Plastic Film Greenhouses
A plastic film greenhouse refers to a framed greenhouse structure covered by plastic sheeting. The plastic film allows sunlight to penetrate while trapping heat and providing weather protection.
Plastic film greenhouses create ideal micro-climates for crop growth. They provide growers with control over temperature, humidity, ventilation, lighting and other environmental factors. Benefits include:
- Higher and earlier yields compared to open-field farming.
- Protection from adverse weather conditions.
- Lower pest and disease damage.
- More efficient use of inputs such as water, fertilizers and pesticides.
- Lower labor requirements per unit of production.
- Extended growing seasons allowing multiple harvests per year.
With these advantages, plastic film greenhouses have become a driving force behind China’s rapid growth in agricultural productivity over the past few decades.
The Benefits of Plastic Film Greenhouses
Plastic film greenhouses produced by China plastic film greenhouse manufacturer provide growers with many advantages compared to conventional open-field farming. By covering crops with transparent polyethylene or other plastic sheets, the greenhouse environment can be optimized for maximum productivity. Some of the main benefits of plastic film greenhouses include:
Controlled Microclimate
Plastic film greenhouses allow for much greater control over the interior temperature, humidity, airflow, lighting and other environmental factors that affect plant growth.
Heating and ventilation systems along with retractable screens, cooling pads and shade cloths allow the ideal growing conditions to be maintained year-round, regardless of outside weather. Sensors and automated climate control systems enable precise management.
The protected environment shelters crops from potentially damaging wind, rain, frost, hail and snow. It also reduces pressure from insects, diseases and weeds.
Higher and Faster Yields
By maintaining optimal climatic conditions, plastic film greenhouses from China plastic film greenhouse manufacturer facilitate faster growth and higher yields compared to open field cultivation.
With protection from weather variability and pests, crop losses are minimized. Multiple harvests per season are possible through manipulation of the light and temperature cycles.
Yields in plastic film greenhouses can exceed open field yields by 2-3 times for fruits and vegetables. The added productivity per acre makes greenhouse farming highly efficient.
Earlier Production
The warmer conditions in greenhouses induces earlier flowering and crop maturation. This enables growers to get produce to market ahead of open field competitors and capture premium prices early in the season.
Tomatoes, cucumbers, peppers and other crops can be harvested up to 1-2 months earlier than traditional field production. Multiple profit-generating harvests are possible within a season.
Better Quality Produce
The protected environment results in lower pest damage and disease incidence in greenhouse produce. The clean, controlled conditions also reduce contamination.
With optimized growing recipes, the color, flavor, size, shape and nutritional content of fruits and vegetables can be improved. Growers can tailor production to meet market specifications.
Plastic film greenhouses are especially beneficial for producing delicate, high value specialty crops that require extra care and attention.
Lower Labor Requirements
Plastic film greenhouses from China plastic film greenhouse manufacturer allow for greater workflow optimization and automation compared to open field farming.
Mechanized drip irrigation booms, movable benches, climate control systems and rail transports help reduce labor requirements per unit of production. Harvests are concentrated over a shorter time period as well.
The more efficient use of labor helps offset the higher initial facility costs, improving profit margins.
Versatility
Plastic film greenhouses can be constructed over a wide range of sizes, from small high tunnels to massive acre-sized complexes containing multiple connected greenhouse units.
Crops from ornamentals to fruits, vegetables, herbs and nursery plants can be grown successfully in controlled environments. This flexibility allows growers to tailor greenhouses to local conditions and high-value crops.
Sustainability Benefits
Greenhouses from China plastic film greenhouse manufacturer provide many sustainability advantages including:
- More efficient use of water through drip irrigation systems, reduced evaporation and recirculation of drain water.
- Recycling of plastic films and greenhouse structural materials.
- Reduced runoff of fertilizers, pesticides and nutrients into the environment.
- Ability to generate renewable energy onsite from solar panels, wind and biofuels.
- Lower carbon footprint by reducing food transport distances when sited near urban centers.
The climate-controlled conditions optimize resource use efficiency for improved agricultural sustainability.
Year-Round Production
By mitigating the influences from outdoor conditions, plastic film greenhouses allow extended seasonal production, from early spring to late fall.
Supplemental lighting facilitates year-round production even in cold winter months. This enables growers to take advantage of high demand periods and provide consumers with fresh local produce regardless of season.
With their many advantages, plastic film greenhouses represent a transformative technology enabling scalable, efficient and sustainable protected cultivation almost anywhere in the world. The benefits they impart are driving rapid adoption globally.
High-Performance Plastic Film Technologies
China plastic film greenhouse manufacturer has developed a vast range of innovative plastic film technologies to optimize greenhouse climates and improve yields:
Multilayer Films
- Double layer films consist of two polyethylene sheets laminated together, providing enhanced durability, thermal insulation and light diffusion compared to single layer films. The additional layer also serves as a backup if the outer layer is damaged.
- Triple layer films take those benefits even further with three layered polyethylene sheets, providing the highest level of light transmission and thermal retention.
- Quad layer films with four layers are also emerging, with each layer having specialized properties. The multiple interfaces between layers create a thermal barrier for improved insulation.
Specialized Plastic Films
- IR thermal plastic films are embedded with inorganic particles that capture and retain far infrared thermal radiation. This can improve greenhouse heat conservation by up to 15% in colder climates, resulting in higher yields.
- Diffuse plastic films use additives to disperse the light and create uniform lighting conditions. This reduces leaf scorching and enhances photosynthesis.
- Anti-fog films are coated with surfactants or inorganic nanoparticles. This prevents condensation from forming on the film which would otherwise block light transmission.
- Photoselective films filter out certain wavelengths of light. This can control plant growth cycles and stimulate flowering.
- Anti-virus films are coated with substances that inactivate viruses and prevent transmission to crops by insects or other vectors. This provides an added layer of crop protection.
- Flame and smoke retardant films contain flame-resistant compounds to reduce fire risk.
High-tech Sensor Films
- Sensor films can detect temperatures, humidity levels, soil moisture and other data. This enables advanced monitoring and control of greenhouse environments.
- Pest warning films contain scent lures which attract certain insects. Early detection of infestations provides timely pest control.
- Self-cleaning films have coatings that breakdown organic dirt through photocatalytic reactions triggered by indoor lighting.
