摘要
利用力学理论和方法,综合分析了水稻茎秆各性状对抗倒伏的影响．突破以往的单性状分析方法,得到水稻茎秆抗倒伏的综合评价指标λ(茎秆柔度),它综合反映了秆长、截面尺寸和形状等茎秆性状．λ是一个无量纲的量,λ值越小,抗倒伏能力越强．
A new method is used here to analyze the effect on rice lodging resistance from rice stem properties by using dynamic theory and method, it is different from the old method which considers only one stem property. According to it, we can get a total indicate A about rice lodging resistance, which has no dimension. The smaller the value of A is, the stronger the rice lodging resistance is.
