Glass greenhouse refers to the greenhouse with glass as the lighting material, belongs to a kind of greenhouse, in the cultivation facilities, glass greenhouse as a form of long service life, suitable for use in a variety of regions and climatic conditions. The industry is divided into different construction models by the size of span and opening, and divided into different ways of use: vegetable glass greenhouse, flower glass greenhouse, seedling glass greenhouse, ecological glass greenhouse, scientific research glass greenhouse, three-dimensional glass greenhouse, shaped glass greenhouse, leisure glass greenhouse, intelligent glass greenhouse and so on. Its area and use can be freely deployed by the greenhouse owner, small courtyard leisure type, large height of up to 8 meters or more, the span of up to 12 meters, the opening of up to 8 meters, the degree of intelligence can be achieved by a key control. Glass greenhouse winter heating problems can be used in a variety of heating methods, its energy costs in the middle, mostly acceptable.

The characteristics of glass greenhouse:

① large area of light, light uniformity.

② long service time, high strength.

Greenhouse structure:

The main structure is made of hot-dip galvanized tubes, and the covering material is made of sunlight board, ordinary or insulating glass, set with aluminum alloy profiles for greenhouse, and sealed with ethylene-propylene rubber strips at the connection between the edges and aluminum alloy profiles.

Glass greenhouse ventilation

The purpose of glass greenhouse ventilation is mainly to exclude the residual heat of the greenhouse and the water in the greenhouse, adjust the air composition inside the greenhouse, and exclude harmful gases, so that the ambient temperature, humidity, and air conditions inside the greenhouse are suitable for the requirements of plant growth.

Glass greenhouse heating

In China's northern region of the glass greenhouse, the need for winter heating, otherwise the winter can not be produced. Greenhouse heating time is not the same, in the northeast region heating time of about 5 months to 6 months, in northern China need 3 months to 5 months. In the south of the region to grow flowers or seedlings also need to be heated or temporary warming.
