摘　　要：2011年第8届全国研究生数学建模竞赛C题是一个农业生产中小麦倒伏问题,在给出3年原始测量数据的基础上要求建立小麦发育后期茎秆抗倒性的数学模型,内容包括小麦性状数据处理和弹性力学模型.综述为C题竞赛总结,含问题的提出、问题的解答与评阅情况、存在问题及研究建议.The problem C in the 8TM National Post-Graduate Mathematic Contest in Molding in 2011 is a problem of the lodging of the wheat＇s in the agricultural production. The mathematic rodel of the lodging-resistance of wheat＇s stem in late growth period need be build on the basis of the data for given in three years. The content includes the data processing on the character of the wheat and elastic mechanics model. In this paper, The problem C is surveyed, and the problem put forward, the solution of the problem, the review status, the existing problems and the research proposal are conclude in the paper.
