盐渍化土壤中氯离子是可溶盐的主要阴离子。它的含量对土壤性质和植物生长有直接影响。土壤中氯离子的测定,通常是用一定的水土比将盐溶出,然后用容量法或电极法测定。由于土壤是一个不均匀的多相体系,土壤中氯离子的含量与土壤水分,温度和植物根系活动等因素密切相关。而且氯离子在土壤中的 Chloride in salinized soils is the main anion of soluble salts. Its content has a direct impact on soil properties and plant growth. Determination of chloride ions in the soil, usually with a certain ratio of soil water to dissolve the salt, and then measured by volume or electrode method. As soil is an inhomogeneous heterogeneous system, the content of chloride ion in soil is closely related to soil moisture, temperature and plant root activity. And chloride in the soil
