江苏省土壤比阻测定的研究

    STUDY ON THE SOIL SPECIFIC RESISTANCE IN JIANGSU PROVINCE

    • 摘要: 为查清我国各地土壤比阻,推荐如下二种方法:第一、在传统犁上安装合适的力传感器来测定各种有代表性的土壤的比阻;第二、建立以粘土成份和土壤含水量为自变量的回归方程来计算土壤比阻。用后者,在不同地区需先校正粘土成分和土壤含水量的值,再以校正值代入回归方程得该土壤比阻的计算值。最后,用统计方法将各地区土壤比阻的实测值和计算值,绘制成该地区的土壤比阻图。

       

      Abstract: In order to find out the soil specific resistance in various regions in China, the following measures are recommended.Firstly, the soil specific resistances of varions reprsentative soil types in various regions are determined with suitable force-scnsing unit, installed in the traditional plow.Secondly, the regression equation for specife soil resistance is established with clay content and moisture content as independent variables.Collecting the available data of clay content and soil moisture content in various regions, and substituting those into the regression equation, the predicated values of soil specific resistance are obtained.Finally, the map of soil specific resistance in various region can be drawn with statistical results of measured values and predicated values.
