The application of new polymer materials in modern agriculture is considered and discussed in a completely new view in this paper. Combined with modern agricultural characteristics: out of season and large-scale planting, the excellent characteristics of modern polymeric materials are skillfully applied to modern agriculture greenhouse rack, which solves many defects of the traditional greenhouse frame structure material. This paper takes Hainan Province as the area of greenhouse structure research and analyze the shed load in the view of structural analysis, based on which the finite element software ABAQUS for the greenhouse framework structure are analyzed by finite element analysis. The results show that the stress and deformation results can satisfy the requirements of structural strength in the normal load conditions.
