Mechanical model of wheat and analysis of root lodging
This paper utilized multi-degree of freedom vibration theory combined with considering the influence of synergy of wind load and self-weight on the wheat to build the five-degree of freedom mechanical model of wheat and calculated the lodging bending moment of wheat root under a certain wind scale,in response to lodging problem in the late period of wheat development.Because of the complicated distribution of root hairs,we put forward the overall model of pedestal pile and calculation formula of lodging-resistant bending moment of wheat root.By comparing these two kinds of bending moment we can predict whether the root lodging of wheat occurs or not.
