摘　　要：本文拟定了火焰光度法测定钾钙肥中有效氧化钾含量的条件 ,与四苯硼钠容量法比较 ,经F检验和t检验 .结果无显著性差异 ,完全可以代替四苯硼钠容量法用于钾钙肥中有效氧化钾的测定 。In this paper,conditions for determining effective potassium oxide contents in K-Ca fertilizer with flame photometry was investigated.Compared with sodium tetraphenylboron volumetric method,the results showed no distinct difference after F and t tests.Being of lower cost and faster,it may therefore be used as a routine method replacing the conventional volumetric analysis.
