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 stalks are an important biological resource, and the research on their mechanical properties is of great significance in the processing and utilization of crops. In this paper, the tensile properties of wheat straw were analyzed and the tensile ability of different growth parts was analyzed comparatively. It was found that the position of wheat straw was more easily broken. At the same time, it is concluded that the moisture content has an important influence on the tensile strength of wheat straw. The performance of the straw with high water content is weaker than that of the straw with low water content, while the straw with low water content is easier than the straw with high water content. fracture.
