摘　　要：从临海农场和方强农场不同类型的具有代表性的地块中采取土样,用离子总和法、残渣烘干法和电导法测定水溶性盐总量,比较并筛选出适宜的测定方法。试验结果表明,两个农场土壤水溶性盐离子组成相似,方强农场土壤水溶性盐含量总体上高于临海农场;土壤水溶性盐测定方法中,残渣烘干法虽然比较准确,但操作繁琐、费时;电导法比较简单、方便、快速,测定结果可以按照特定计算式换算成土壤水溶性盐质量浓度。The different composition and content of water-soluble salts in different soil, which were taken from Linhai farm and Fangqiang farm, were examined by summary of ions, mass of dried -residues, electrical conductivity measurement, aiming to find out the optimal method of examining water-soluble salts in soil. The results showed that each kind of water-soluble salt ions had similar content in soil of the two farms, yet varied ions content in soil of Fangqiang farm was higher than that of Linhai farm. These 3 methods had different characteristics that electrical conductivity measurement was simple, convenient and quick, while mass of dried-residues was more exact but complex and time-wasting.
