Five main stalk crops planted in northern China including wheat, corn, broomcorn, soybean, and millet, were chosen to be the samples of the experiments. About seven morphological traits (such as plant height, ear length, ear weight, moisture content and so on) were measured in the crop mature period. The maximum shear force during shearing process, through static test equipment, at the second internode of the basal stalk, was recorded. And shear strength of each crop was calculated to find the differences of shear strength among different crops. The optimal regression models of shear force and morphological traits were obtained by multiple linear regression method with Statistics Analysis System. The equation based on the regression models was constructed.
本文以北方主要茎秆作物(小麦、玉米、高粱、大豆、谷子)为研究对象,试验测定了成熟期茎秆基部第二节间的最大剪切力及株高、穗长、穗重、含水率等七种形态特性指标,获得了静载情况下相关样本的剪切强度;分析比较了不同茎秆作物剪切强度的差异性,并利用SAS软件对茎秆作物剪切力与形态特性指标进行了多元线性回归,得到了剪切强度对形态特性指标的最优回归方程。
