Abstract  

In order to reveal the biomechanical response mechanism of plants to wind erosion, to select proper windbreak trees, we took branches of six common plants in open-pit coal mine dump of Zhungeer, Inner Mongolia as the object. Indoor instantaneous limit tensile test was done on the ultimate tensile strength, concerning the branches size, loading speed and moisture conditions of the branches. The results showed that, the tensile strength of the tested plant branch with diameter range of 0-3 mm increased with increasing loading rate but decreasing diameter; the ultimate tensile strength order is Caragana Korshinskii (50.13 MPa)>Hippophae rhamnoides (37.27 MPa)>Medicago sativa (30.25 MPa)>Astragalus adsurgens Pall (22.74 MPa)> Melilotus officinalis (22.22 MPa); the moisture loss rate of finer branches was higher, and the ultimate tensile strength of the finer branches was higher too when become dry.

Key words:  branch      ultimate tensile strength      diameter      water loss rate      speed of leading
