摘要
农作物秸秆是一种重要的生物资源,对其力学特性的研究在农作物的加工利用方面有着重要意义。文中实验研究分析了小麦秸秆的抗拉特性,比较分析了不同生长部位的抗拉能力,判定出小麦秸秆中部位置较易断裂。同时得出含水率对小麦秸秆的抗拉能力有重要的影响,其表现为含水率高的秸秆抗拉性能弱于含水率低的秸秆,而含水率低的秸秆却比含水率高的秸秆容易断裂。
Crop straw is an important biological resource. To study the mechanical characteristics is of great significance in the processing and utilization of crops. Experimental research and analysis of the tensile properties of wheat straw and a comparative analysis of the tensile strength of the different growing siteS are carried out to determine wheat straw fracture more likely occurs in the central position. At the same time arrives at a conclusion that the tensile strength of the wheat straw is influenced by the moisture content： the wet straw is less tensile than the dry straw, but the dry straw is easier to break than the wet straw.
