Multispan greenhouse:
In the seasons that are not suitable for plant growth, it can provide a growth period and increase yield. It is mostly used for plant cultivation or seedling raising of temperature-loving vegetables, flowers, and trees in the low temperature season. There are many types of greenhouses, which can be divided into many types according to different roof materials, lighting materials, shapes and heating conditions, such as glass greenhouses, plastic polycarbonate greenhouses; single greenhouses, multi-span greenhouses; single roof greenhouses, double Roofing greenhouse; heated greenhouse, unheated greenhouse, etc. The greenhouse structure should be sealed and thermally insulated, but it should be convenient for ventilation and cooling. Modern greenhouses have equipment for controlling temperature, humidity, light and other conditions, and are automatically controlled by computers to create the best environmental conditions for plants.
Greenhouse Feature:
The greenhouse is a building that uses daylight covering materials as all or part of the enclosure structure material and can be used for cultivation of plants in winter or other seasons that are not suitable for the growth of open plants.
Large-scale multi-span plastic greenhouse is a type of greenhouse that has emerged and developed rapidly in the past decade. Compared with glass greenhouses, it has the advantages of light weight, low amount of skeleton materials, low shading rate of structural parts, low cost, and long service life. Its environmental regulation ability can basically reach the same level as glass greenhouses. Plastic greenhouse users accept The ability is far higher than the glass greenhouse in the world, and has become the mainstream of the development of modern greenhouses.
Greenhouse Size:
Multispan greenhouses have different structural sizes in different countries. But overall, the general greenhouse span is 6m~12m, the opening is about 4m, and the eaves height is 3~4m. For multi-span greenhouses based on natural ventilation, the maximum width of the greenhouse should be limited to 50m, preferably about 30m, when the side windows and ridge windows are used in combination; and the maximum width of the greenhouse can be Expand to 60m, but it is best to limit it to about 50m; for the length of the greenhouse, (in terms of ease of operation) it is best to limit it to less than 100m, but there is no strict requirement.
