Abstract—With the application of elastic parameter test method of composite material mechanics, UTM6503 PC-controlled universal testing machine was adopted to study the characteristics of axial compressive mechanics on the xylem and the whole stalk in the paper. The test result showed that the average axial compressive elastic modulus of the ramie xylem of first crop of “Zhongzhu No.1” was 374.70 MPa and the average maximum compressive strength was 13.71 MPa, while the average axial compressive elastic modulus of whole stalk was 336.40 MPa, and its average maximum compressive strength was 13.19 MPa; there was no significant difference between the elastic modulus and the compressive strength of the ramie xylem and the whole stalk. In the stalk composition, xylem and phloem bond on the surface depending on their own adhesion strength which was not able to prevent the phloem slipping away along the surface of xylem. In the compressive test, it showed the load-bearing function of xylem more.
