摘　　要：使用同种FDR对3种不同性质土壤的率定和检测,考察现有的率定及检测方法的适用性。结果表明:不同类型土壤标准土样制备及仪器检测方法研究中所提出的率定及检测方法切实可行,3种土壤中所得出的检测数据与烘干数据对比绝对误差均小于2%,达到规范规定要求,潮土在FDR上所得出的检测数据要好于红土和黑土,综合以上结果,建议使用亳州潮土作为标准土壤进行实验室检测。The article inspects the applicability of the proposed method for calibration and detection, using of the same FDR for the calibration and detection of three different types of soils. The results show that： Calibration and detection method for different types of standard soil sample preparation and testing methods is feasible; The absolute error of the data obtained from the three soils compared with the drying data is less than 2%, meeting the specified requirements; The test data of Fluvo-aquic soil in the FDR is better than laterite and black soil. The above results show that the use of Bozhou fluvo-aquic soil as the standard soil for laboratory testing is advised.
