摘　　要：通过实验比较磷钼酸喹啉重量法和磷钒钼黄比色法对8个不同类型水溶肥料样品磷含量的测定过程、测定结果及准确性等。结果表明:两种测定方法所测得的结果均符合质控要求,且相关性高,相关系数为0.999。相比较而言,比色法具有准确性高、操作简单、耗时短等优点,可以作为企业内部的快速检测方法。Based on the experiment, the process, results and accuracy ot two determining methods （phosphomolybdic acid quinoline weight method and phospho vando molybdic yellow colorimetry） of phosphorus in eight different types of water soluble fertilizer samples are compared. The results show that, the results of two methods is conform to the requirements of the quality and with high correlation, coefficient of 0.999. Compared with weight method, colorimetry has high accuracy, simple operation, short time consuming, can be used as a rapid detection method of enterprise.
