Multi span greenhouse series:
Suitable for regional use with a wind speed of 25 meters per second and a snow load of 0.2 kilonewtons per square meter.
This greenhouse is suitable for large-scale production of vegetables, flowers, etc. The products have been tested in the market and have a high cost-effectiveness.
Most of the components in this greenhouse are universal, interchangeable, and have the advantages of simple structure and easy installation.
Features:
A connected greenhouse is an upgraded version of a greenhouse, which is actually a large greenhouse that connects the existing independent single room greenhouses using scientific methods and reasonable design. Or it can be understood as an expansion.
1. Ventilation, air exchange, and dehumidification. Ventilation is a good way to reduce humidity. Ventilation must be carried out at high temperatures, otherwise it will cause a decrease in indoor temperature in multi span greenhouses. If the temperature drops too quickly during ventilation, the ventilation opening should be closed in a timely manner to prevent the vegetables from being harmed by a sudden drop in temperature.
2. Cover with plastic film. The use of plastic film covering can reduce the evaporation of soil moisture and is an important measure to lower indoor air humidity.
3. Raise temperature and lower humidity. This method can meet the temperature requirements of vegetables and reduce the relative humidity of the air. When the plant grows to have resistance, water it and close the greenhouse to raise the temperature to about 30 ℃ for 1 hour, then ventilate and remove moisture. When the greenhouse temperature drops below 25 ℃ 3-4 hours later, it can be repeated once.
4. Use insulation curtain materials with good moisture absorption properties. Thermal insulation curtain materials with good moisture permeability and absorption, such as non-woven fabric, can prevent condensation on the surface of the greenhouse and prevent dew from falling onto the plants, thereby reducing the air humidity in multi span greenhouses.
5. Natural moisture absorption. Materials such as straw, wheat straw, and quicklime can be used to spread between rows, adsorbing water vapor or mist to achieve the purpose of moisture reduction.
Function:
Multi span greenhouse is an economical greenhouse that is popular among users for its beautiful curved shape and low cost. The curved ceiling is beautiful and elegant, with a smooth line of sight. The structure uses less steel and has good insulation performance. The manufacturing cost is relatively low, making it an economical greenhouse suitable for most regions of China. Double layer film greenhouses are commonly used in northern regions, while single film greenhouses are more commonly used in southern regions. It can obtain light in the visible light range of 0.4-0.7 microns. After the layer film is inflated, it can form thick airbags, effectively preventing heat loss and preventing the intrusion of cold air. The use of double-layer inflatable film can greatly improve the greenhouse insulation performance and save operating costs. The top of the covering material is covered with polyethylene drip free longevity film, with an outer layer that is UV resistant and an inner layer that is anti dew; Polyethylene drip free longevity film or polycarbonate hollow board can be used to cover the surroundings according to user needs.
