A plastic film garden greenhouse, also known as a plastic greenhouse or polyhouse, is a structure commonly used in gardening and agriculture to creat a controlled environment for plants.
Srtucture and Masterial:
Frame: Usually it is constructed with hot dip galvanized steel or aluminum. This frame provides the necessary support and stability to hold the plastic film covering.
Covering Material: Usually use 120/150/200micron meter plastic film. It is high-quality plastic film. Commonly used polyvinyl chloride(PVC) and polythylene(PE). The plastic film allows sunlights to penetrate, which also trapping heat inside, creating a warm and protected space for plans. It is relatively lightweight, cost-effective, and easy to install and maintain.
Functions and Benefits:
Temperature Regulation: One of the primary functions is to regulate temperature. It can keep the interiorwarmer than the outside environment during cold seasons, protecting plants from frost and low temperatures. In hot weather, ventilation systems can be installed to control the temperature and prevent overheating.
Moisture Control: The plastic film helps to retain moisture inside the greenhouse. It reduces water evaporation from the soil and plant surfaces, maintaining a more consistent level of humidity, which is beneficial for plant growth. This can also lead to more efficient water use as less water is lost to the atmosphere.
Protection from Pests and Diseases: The enclosure provided by the plastic film acts as a physical barrier against many pests and diseases. It reduces the access of insects, birds, and other animals that may damage the plants. Additionally, the controlled environment makes it easier to monitor and manage the spread of diseases.
Extended Growing Season: By creating a favorable environment, a plastic film garden greenhouse allows gardeners to extend the growing season. It enables the cultivation of plants that would not otherwise survive in the local climate, allowing for earlier planting in the spring and later harvesting in the fall.
Applications Home Gardening: Many homeowners use small plastic film greenhouses in their gardens to grow a variety of plants, including vegetables, fruits, and flowers. It provides an opportunity to enjoy fresh produce and beautiful blooms throughout the year and experiment with different plant varieties.
Commercial Agriculture: On a larger scale, plastic film greenhouses are widely used in commercial agriculture. They are used to grow high-value crops such as tomatoes, cucumbers, and strawberries, ensuring a steady supply of fresh produce to the market regardless of the season.
Research and Education: Greenhouses are also important in research institutions and educational settings. They provide a controlled environment for conducting experiments on plant growth, development, and responses to different environmental factors. Students can learn about plant biology and horticulture in a hands-on and practical way.
In conclusion, the plastic film garden greenhouse is a versatile and valuable structure that offers numerous advantages for plant cultivation, making it an essential tool for gardeners, farmers and researchers alike.
