Results show 1 the total water requirement of the crops in the Jinghe Watershed is 740543.20×10^4 m^3, accounting for 41.58% of the total water requirement of the region; 2 of the two major groups of crops, grain crops are higher than cash crops in water requirement quotas; and among specific crops, vegetables, melons, rice and cotton are higher and sunflower, potato and benne are lower than other crops; 3 water requirement per hectare varies from county to county with the highest being 5682m^3hm^(-2), in Jingyang County, and the lowest 4022 m^3hm^(-2) in Dingbian County, averaged to 4 583 m^3hm^(-2), but the water requirement quota of a crop does not vary with the county, so calculation of water requirement quota of a county is closely related to its cropping structure; and 4 because of serious waste of water in farming, the actual water consumption in agriculture in the region is much higher than the calculated crop water requirement.

结果表明，泾河流域农作物需水量总计740543.20万立方公尺，农作物需水占总需水量的比例较高，为41.58%。粮食作物需水定额较经济作物高；就具体作物而言，菜、瓜类、水稻、棉花等需水定额较高，向日葵、薯类、胡麻等较低。各县单位面积需水量差异较大，平均值为4583立方公尺hm^(-2)；泾阳县最高，为5682立方公尺hm^(-2)，定边县最低，为4022立方公尺hm^(-2)。由于事先设定大多数作物的需水定额不随县的改变而改变，因此需水量与作物结构密切相关。农业用水浪费严重，使泾河流域农作物实际用水量远高于需水量的理论计算值。

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。
