Abstract: Kiwifruit as a kind of economic crops of vines, and its planting cultivation needs to provide support.A well-designed scaffolding can not only facilitate management of ground operations, but also make full use of land space, improve ventilation and lighting conditions, reduce crop diseases and pests to do harm to the crops, and improve crop yield and quality.This paper selects the three forms of cultivated kiwifruit scaffolding (wall fence, “T”shaped frame, flat ceiling frame) , it carries out the finite element analysis in the situations of the wind load and hoisting load coupling respectively.And according to the results of the analysis to optimize the scaffolding structure, in order to improve the stability and safety of the scaffolding.Results show that both ends of the top wall fence shaped scaffolding anchor wire drawing and column bottom maximum axial force;the maximum bending moment of“T”shaped frame occurs at both ends of the wire drawing;The axial force of wire drawing and anchor wire around the flat ceiling frame is maximum, and the maximum bending moment occurs between the crossbeam and the drawing wire.According to the numerical simulation, it can be found the weak link of each kind of scaffold and provides reference for the selection of other economic crops.
