Product Description

Glass greenhouse is a modern agricultural facility with numerous unique features and advantages.
The glass greenhouse uses high-strength glass as the covering material, which has good transparency. Adequate sunlight can penetrate glass, providing even and sufficient light for indoor plants, promoting photosynthesis, and facilitating plant growth and development. For example, in flower cultivation, high-quality lighting conditions can make the flowers more vibrant in color and have a longer flowering period.
It has excellent insulation performance. The use of good sealing structure and insulation materials can effectively reduce heat loss and maintain a relatively stable indoor temperature even in cold seasons. When planting vegetables in winter, it can ensure that the vegetables grow in a suitable temperature environment and are not affected by severe cold.

Glass greenhouses can also achieve precise environmental control. By equipping advanced ventilation, cooling, humidification, fertilization and other systems, indoor environmental parameters such as temperature, humidity, and carbon dioxide concentration can be accurately adjusted according to the growth needs of different plants. For example, when planting strawberries, environmental parameters can be adjusted according to the different stages of strawberry growth to improve the yield and quality of strawberries.
In addition, the durability of glass greenhouses is also one of their prominent features. High quality frame structure and glass materials can withstand the test of severe weather conditions, such as strong wind, rainstorm and snow.
Overall, glass greenhouses provide a controllable, stable, and efficient environment for agricultural production, helping to increase the yield and quality of agricultural products and promoting the development of modern agriculture.

 

Greenhouse parameters mainly include the following aspects:
1. Greenhouse size
Length: Usually ranging from tens of meters to hundreds of meters, common ones include 60 meters, 80 meters, 100 meters, etc.
Width: Generally between 8 meters and 16 meters, such as 8 meters, 10 meters, 12 meters, etc.
Height: The ridge height is commonly around 4 to 6 meters, such as 4.5 meters, 5 meters, and 5.5 meters.
2. Coverage material parameters
Glass types: Common ones include ordinary float glass, tempered glass, etc.
Glass thickness: usually between 4 millimeters and 6 millimeters.
Transmittance: The transmittance of high-quality glass can reach over 90%.
3. Temperature parameters
Daytime suitable temperature: Depending on the different crops planted, it is generally between 20 ºC and 30 ºC.
Nighttime minimum temperature: usually not lower than 10 ºC.
4. Humidity parameters
Suitable relative humidity: For most crops, it is between 50% and 80%.
5. Ventilation parameters
Ventilation area: a certain proportion of the total area of the greenhouse to ensure good ventilation.
Ventilation methods: such as natural ventilation, mechanical ventilation, etc.
6. Lighting parameters
Light intensity: The amount of light energy received per unit area, with different crops having different requirements.
7. Load bearing parameters
Snow load: The maximum weight of snow that can be sustained.
Wind load: The maximum wind force level that can be resisted.
For example, in some areas where the snow load is high in winter, the design of greenhouses needs to consider being able to withstand snow pressure of tens of kilograms per square meter; In windy areas, wind load parameters may need to reach a level that can withstand wind speeds of ten or even higher.

The service life of glass greenhouses is usually around 15 to 20 years, but this depends on multiple factors.

If the greenhouse uses high-quality building materials, such as high-quality steel frames and glass with appropriate thickness and excellent quality, and strictly follows design specifications and construction standards during the construction process, coupled with regular maintenance and upkeep in the later stage, its service life may reach 20 years or even longer.

For example, some carefully designed and constructed large modern glass greenhouses, with good maintenance and over 20 years of use, still have stable performance and can meet the needs of agricultural production.

However, if the quality of materials used during construction is poor, or if there are defects in the construction, or if necessary maintenance is lacking during use, such as not clearing snow in a timely manner, not treating rust on the frame, etc., the service life of the glass greenhouse may be shortened to about 10 years or even shorter.

In addition, environmental factors can also have an impact on the service life. Under severe weather conditions, such as frequent strong wind, rainstorm, extreme temperature, etc., the greenhouse structure may also be damaged, thus shortening its service life.
