摘　　要：采用土壤常规测试法和速测仪测试法,对6种典型类型土壤样品的主要属性进行了对比分析测试。统计分析结果表明,两种方法测试土壤硝态氮、有效磷、速效钾和有机质结果间均具有较好的线性相关性。速测法平行测试的结果有较高的精密度和稳定性,但不同时间测试结果的精密度和稳定性较差。常规法测试结果的精密度和稳定性仍然优于速测法。The routine and rapid method of soil property parameters were used in this study to analyze 6 kinds of typical types of soil samples. Statistical analysis results showed that results of soil nitrate nitrogen, available phosphorus,available potassium and organic matter measured by the two methods had good linear correlation. The parallel test of the rapid method had high precision and stability,but poor precision and stability in different time. The precision and stability of the routine method was still better than that of the rapid method.
