| Abstract: | In this paper,wheat stalks in their fully mature stage were researched.Tensile and bending tests were carried out,on wheat stalks of different fertilization conditions(with and without fertilizatioin),to obtain the Young's modulus,bending ridigity and relevant changing trends.Based on the experimental.data,the Young's modulus ranged from 2.371 to 2.604Gpa,the Young's modulus of sheath ranged from 1.246 to 21.391Gpa,the rigidity modulus of stalk with sheath ranged from 0.0067 to 0.0104 Nm2 This study will not only provide a reference for the high-producing and breeding,but also be a fundamental study of wheat lodging. |
