采用铍试剂Ⅲ分光光度法来测定土壤中有效硼的含量,方法用于多土壤中的有效硼分析,测定值符合标准值。对国家土壤标准物质进行测定,方法精密度(RSD,n=12)为2.58%-7.26%。
The beryllium reagent Ⅲ spectrophotometric method was used to determine the content of available boron in the soil. The method was applied to the analysis of available boron in multiple soils. The measured values were within the standard values. The determination of national soil reference materials, method precision (RSD, n = 12) was 2.58% -7.26%.
