“The form of the skeleton curve of a solar greenhouse directly affects the lighting and mechanical bearing performance of the front roof. In order to study and design a reasonable skeleton curve form, based on the design characteristics and application situations of existing skeletons, the numerical construction and expression methods of the reasonable curve of the solar greenhouse skeleton were studied. The research progress in the field of greenhouse structure optimization was introduced. The research team established a double parabolic skeleton curve system, providing a solution for balancing lighting and bearing in northern solar greenhouses.”
