我国盐渍土面积大、分布广而且类型多．我们为了盐渍土的分类、改良利用，要求能够迅速准确地得到盐分含量的信息．经典的方法是野外采样，在化验室分析，一般采用重量法测定盐分重量，后来发展到容量法[1]，即土壤经浸提后分别测定离子的含量，然后累加在一起便是其含盐量，此
Saline soil in our country is large in area, widely distributed and many types. In order to classify and improve the use of saline soil, we request that information on salt content be quickly and accurately obtained. The classic method is field sampling, analysis in the laboratory, the weight of salt is generally used to determine the weight, and later developed to the volume method [1], that is, the soil after leaching were measured ion content, and then added together is its salt Amount of this
