摘要
测定了海河流域14个褐土样品和8个浅色草甸土样品不同形态S含量及有关的土壤性质.回归统计结果表明,土壤中水溶性S的含量,或水溶性S加上吸附性S的总量,与土壤悬液电导率之间的相关系数r=0.97,二者呈线性关系;土壤有机S含量与有机质含量成正相关.
The contents of different forms of sulfur for 14 samples of brown soil and 8 samples of light coloured meadow soil in Haihe river region were determined. Statistical calculation showed that the relationship between the contents of water soluble sulfur, or the sum of water soluble sulfur plus adsorbed sulfur, and the electrical conductivities of soil suspension is linear with the coefficient r being 0.97, and contents of organic sulfur are related to that of organic matter in soils.
