摘要
小麦的高产和抗倒伏是相互制约的。文章利用力学原理建立力学模型,从而推倒出小麦茎秆在无风情况下的临界穗重和有风情况下小麦茎秆的临界风力、穗重、茎秆长度和弹性模量的关系。为育种专家在不同地区培育不同形态、不同产量的小麦品种提供理论依据。
The wheat' s high yield and its lodging-resistance are contradictory. A dynamic model for wheat stem is established by using dynamic theory and method. According to it, the critical wheat grain weight without wind load and the relation between the critical wind and the wheat grain weight, stem length, elastic modulus when the wind load exists can be obtained. These results provide a theoretical basis for breeding experts to foster different forms and different yield of wheat in different areas.
