High -efficiency greenhouse greenhouses can carry out crop seedlings and production work in a more stable climate environment. Increased environmental unstable probability of environmental instability, and some areas that are not suitable for planting also need fresh vegetables such as vegetables, so it is necessary to have a high -efficiency and low -carbon -saving greenhouse building to achieve planting needs. Then the design building of high -efficiency planting greenhouses needs to be paid attention to.
High -efficiency planting glass greenhouses in developed countries such as the Netherlands, Europe, and the United States are very high. This has a lot to do with its high -growing technology product quality products A and product prices. It takes more than 20 years to use, but it still makes many investors discourage. Furthermore, it is a model promotion demonstration role in high -efficiency planting. At present, many such projects in the country. However, there are also some large agricultural companies and groups for development and production in the agricultural field. Only by selecting the right starting point can the next design discussion and construction stage be carried out.
According to local conditions, the selection of suitable greenhouse system material planting greenhouses consist of the cooperative work of various systems and materials. The standard -efficient planting greenhouse system includes an external shading system, internal shading and thermal insulation system, the top natural ventilation system, the natural ventilation system of the wall, the compulsory air cooling system, the high -waisted zero -cooling system, the heating system, the internal climate circulation system, Plant root climate circulation system, carbon dioxide supplementary system, planting cultivation tank system, and integrated water and fertilizer system. It is worth noting that the use of the appropriate cooling system in summer will reduce the use of energy consumption. Choose appropriate heating energy according to local resources in winter.
The traditional greenhouse greenhouse coverage materials are applied to thin films, sunlight, and ordinary glass; now we can choose low -iron super white fragrant pear glass on the top of the greenhouse. The light transmission rate increases by about 7.5%, and the corresponding output will increase the same proportion.
