Multi-span energy saving sunlight greenhouse

Abstract

The invention discloses a multi-span energy saving sunlight greenhouse which comprises ground ridge walls, gable walls, a back wall, a skeleton and greenhouse film. The multi-span energy saving sunlight greenhouse is formed by connecting a group of single-pitch sunlight greenhouses in tandem arrangement, and two rows of symmetrical support columns in parallel arrangement are arranged between neighboring greenhouses; a decking is installed at the top of each support column, the rear end of the front greenhouse skeleton is overlapped and fixed on the beam of the support columns in the front row through connecting seats, the front end of the rear greenhouse skeleton is overlapped and fixed on the beam of the support columns in the rear row through connecting seats, and then the single-pitch sunlight greenhouse is connected into a whole; as the distance between the front greenhouses and the rear greenhouses is eliminated, the utility ratio of land is enhanced greatly, the area of sunlight greenhouses increased greatly, and the utility ratio of land can reach 80% to 90%, which meets the requirements of large-scale production of sunlight greenhouses, realizes mechanized production, improves growing conditions for crops, enhances crop output and reduces warming expenses. The invention has the characteristics of low cost and high profit.

Description

technical field [0001] The invention relates to a solar greenhouse, in particular to a multi-span energy-saving solar greenhouse, which is suitable for early or delayed large-scale production of various flowers, fruits, vegetables and crops on slopes. Background technique [0002] At present, solar greenhouses are the main source of energy from sunlight, which can be used for crop production without heating in cold winters, or with a small amount of heating in extremely cold conditions. With the popularization and development of solar greenhouses in rural areas, urban residents in northern my country can still watch various flowers and eat fresh and delicious vegetables and fruits even in the cold winter, which not only brings huge economic benefits to farmers, but also enriches In order to improve the daily life of urban residents in winter, solar greenhouses have become the main body of northern facility agriculture. However, this kind of solar greenhouse is usually a sing...

AI Technical Summary

Problems solved by technology

However, this kind of solar greenhouse is usually a single-slope structure. In order to ensure the lighting requirements of the solar greenhouse, the distance between each single-slope solar greenhouse must be kept nearly one shed span, resulting in low land utilization. The small indoor area cannot meet the requirements of large-scale production on slopes, let alone mechanized production, which brings inconvenience to the large-scale production of solar greenhouses
