小麦茎抗倒伏的力学分析及综合评价探讨

摘要

A new mechanical model of the wheat stem was constructed. Taking into account the impact of stem and ear, the critical wind force the stalk can withstand was calculated with the model, which can be used to determine the lodging resistance of the wheat stem. This article showed the relationship of the lodging resistance of wheat with the length and weight of wheat ear, providing certain references for the selection of high-yield wheat plant type.%建立了小麦茎秆的力学模型,综合考虑茎和穗的影响,利用力学方法和理论,求出茎秆能承受风力的大小,并以此作为小麦茎秆抗倒伏的指标,判断其抗倒伏能力.将抗倒伏能力与麦穗的长度和重量联系起来,可为高产小麦株型的选择提供参考.
