| Abstract: In order to solve the problems of small space, unsuitable mechanized operation and low level of production mechanization in traditional greenhouses, the greenhouse was constructed adopting a suitable mechanized large-span structure, which optimized the height of the traditional greenhouse roof ridge, rear wall height, front and rear roof angles, and reasonably designed the entrance and exit positions to facilitate the entry and exit of operating machinery. The new type of greenhouse had a high level of mechanized production, high land use effi ciency and higher insulation performance than traditional greenhouses. |
