摘　　要：小麦是我国主要粮食经济作物。本文对其茎秆的拉伸、剪切、弯曲、压缩等力学性能的研究进展进行了简要回顾,对现有研究存在的不足进行了简要分析。国内外的相关研究均忽略了小麦茎秆上鞘的存在对小麦茎秆力学性能的影响,鲜有文献分析小麦茎秆的力学性质与机具的相互作用。将小麦茎秆力学性能与现有的仿真分析技术结合,将有利于小麦茎秆力学性能的发挥及农业机械的设计与优化。Wheat is an important crop in China.The developments of the straw mechanical properties,such as stretching,shearing,bending and compressing both here and abroad were briefly reviewed.Among all the researches,the effect of leaf blades and sheath was commonly ignored;and the interactions be-tween mechanical property and machine were seldom studied.The combination of the wheat straw mechanical properties and simulation technologies is good for the development of wheat straw mechanical properties and improves the design of agricultural machine.
