本文采用轴向拉伸试验和悬臂梁试验，研究3a～4a生的白沙蒿、柠条和沙棘枝条的抗拉特性和抗弯特性。结果表明：3种植物枝条的抗拉特性相似，其抗拉力均随直径的变化呈幂函数增大的趋势，抗拉强度随直径的增大呈幂函数减小的趋势，3种植物枝条的抗拉力和抗拉强度比较均为柠条〉白沙蒿〉沙棘。3种植物枝条的抗弯特性为：柠条和沙棘枝条的抗弯力与直径呈幂函数正相关关系，白沙蒿枝条的抗弯力与直径呈线性关系。3种植物抗弯强度均随直径的增大而减小。

Tensile characteristics and bending of Artemisia sphaerocephala Krasch, Caragana microphylla Lam. and Hippophae rhamnoides L. which were 3 to 4 years old were measured by cantilever test and axial tensile test. The results showed: There were the same nile of the tensile characteristics of 3 kinds of branches. The anti - tension of 3 kinds of branches and diameter showed a positive power function. Tensile strength was reduced in different degree follow the diameter increasing. The result was Caragana microphylla Lam. 〉 Artemisia sphaerocephala Krasch. 〉 ltippophae rhamnoides L. when the anti - tension of 3 kinds of branches were compared. Bending strength of 3 kinds of branches showed a negative power function with diameter. And it was the same with tensile strength. Bending force and diameter of Carctgana microphylla Lam. and Hippophae rhamnoides L. branches showed a positive power function, but Artemisia sphaerocephala Krasch was linear relationship. Bending strength of 3 kinds of branches showed a negative power function with diameter.
