Notes Winter wheat is grown in the furrows sides at the mature stage of soybean crops. In order to reduce winter wheat no-tillage seeder stroke soybean stem in sawing, the mechanical properties in terms of moment of inertia, the elastic modulus and bending stiffness parameters of soybean stem were measured. We found that the inertia in four to six internode was the largest, the middle of elastic modulus was minimum, and bending stiffness was linear decrease. The correlation between microstructure of soybean stem and stem mechanical properties were also studied. The results showed that soybean stem bottom shear stress and bending stiffness were higher than the other two parts, which withstood greater impact force. These conclusions can provide basic parameters for the design of winter wheat no-tillage seeder.
