Glass intelligent greenhouse is a relatively fixed cultivation facility used for a long time. Therefore, before greenhouse construction, planning should be carried out, especially for the large-scale and centralized multi span greenhouse construction base. According to the natural environmental conditions, scientific and reasonable overall arrangements should be made for the direction and layout of greenhouse, roads, pools, ditches, houses and other facilities in the base, so as to ensure the convenience of future production management and the effective use of land and lay the foundation for high yield.
Environmental characteristics venlo glass greenhouse:
(1) High transmittance and uniform light
Due to the characteristics of load-bearing structure, the roof of Wenluo glass greenhouse adopts high light transmittance glass as lighting material. At the same time, the special aluminum profile is used as the roof beam, which greatly reduces the cross-sectional size of the roof beam, increases the roof and connectors, reduces the power failure of the whole roof system, and greatly improves the light transmittance of the whole greenhouse. This kind of Wenluo glass greenhouse comes from all over Europe. This feature well adapts to the characteristics of low light in winter in Europe and has become an important factor in its wide promotion and use. In addition, because the engine room surface adopts the same structure, the distribution of greenhouse light is more uniform, which creates conditions for the uniform light of crops. It is especially suitable for greenhouse seedling raising and flower production with high light consistency requirements.
(2) the greenhouse has good sealing performance
Wenluo glass greenhouse adopts special aluminum alloy, supporting rubber strips and injection molded parts as glass greenhouse components, which greatly improves the tightness of the greenhouse.
(3) large ventilation area
Compared with other greenhouses of the same span, Wenluo greenhouse has 2 ー 4 pairs of roofs, that is, 2 ー 4 pairs of ridges and gutters. Therefore, the same ventilation as other greenhouses with the same span can be obtained by using the method of spacing windows. Generally speaking, the ventilation capacity of the greenhouse is about 10% of the ground area of the greenhouse.
(4) high roof drainage efficiency.
Because there are 2 ~ 4 gutters in each span of glass greenhouse, the catchment area of each gutter is reduced compared with other types of greenhouses in the same span
(5) strong flexibility
The application of truss roof joist makes the development of Wenluo glass greenhouse have greater use and flexibility. Because the height of truss joist is 350 ~ 850 mm, it provides sufficient installation network space and support position for the installation of mechanism, curtain pulling system, crop suspension control system and other equipment.
