Speaking of greenhouses, the first thing we think of is plastic greenhouses, because the solar greenhouses in the north and the ground-inserted greenhouses in the south are the most used greenhouse styles in the planting industry in the past few decades, but have you ever seen a greenhouse made of glass? What are the advantages of glass greenhouses, and is the cost of glass greenhouses very expensive? Qingcheng Agriculture will share with you.
1. Introduction to Glass Greenhouse
A glass greenhouse refers to a greenhouse with glass covering materials on the top and all sides. This type of greenhouse must be a patterned type, that is, a spire-shaped glass greenhouse. The development of this kind of greenhouse was passed by a small town in Wenlo, the Netherlands. After nearly half a century of development, it has gradually become the current glass greenhouse with three spires.
In order to adapt to the application in different regions, the glass greenhouse gradually improved and installed external shading system, internal shading system, internal thermal insulation system, fan and water curtain cooling system, high-pressure spray system, and electric window ventilation system. The top of the glass greenhouse is covered with 4mm tempered or 5mm tempered glass. The surroundings are covered with 5mm tempered or double-layer hollow glass.
The span of the glass greenhouse is 8m, 9.6m, 12m, 16m, and the size of the bay is 4m, 8,m. The height of the column ranges from 4 to 8 meters, and the most conventional height is 6 meters.
2. The advantages of glass greenhouses
①More environmentally friendly
The long service life of glass greenhouses is generally more than 15 years, and the service life of plastic greenhouses is three to five years. The use of glass greenhouses reduces the occurrence of white pollution from the source, which is more environmentally friendly and reduces the use of fossil fuels.
② Higher light transmittance
Glass is a kind of mineral material. The light transmittance of glass is as high as 91% or more, and it will not attenuate with the attenuation of service life. For most vegetables, the higher the light transmittance, the greater the output of vegetables. high.
③High degree of automation
After the development after industrialization, the glass greenhouses have all realized the transformation from mechanization to intelligence. You only need to control the opening and closing of the various systems of the glass greenhouse on the computer or mobile phone app, and can be automated.
3. The cost of glass greenhouses
The price of glass greenhouses is twice as high as that of traditional thin-film vegetable greenhouses, but the cost gap between the two is not large in terms of their average spread to service life. The cost of a glass greenhouse ranges from 280 to 500 yuan per square meter, depending on the size, area, and height of the greenhouse. Qingcheng Agricultural Professional provides greenhouse design, greenhouse budget, greenhouse materials, and greenhouse construction.
