通过21个耕层土壤和2个剖面土壤样品分析表明,黄潮土耕层总S在115.80~318.82mg/kg之间,平均229.17mg/kg,总有机S、无机S、C—O—S、C—S和惰性S分别占总S的94.8%、5.2%、54.8%、5.7%和35.1%,有机C分别与总S、总有机S、C—O—S和C—S之间有显著直线相关;总S分别与总有机S、惰性S之间有极显著相关,总S与C—O—S之间有显著相关关系。随着剖面的加深,C—O—S、C—S和总有机S占总S比率逐减,而惰性S和无机S却逐渐增加。黄潮土质地粗,有机C低、SO_4~(2-)淋失严重,有缺S可能。 The analysis of soil samples from 21 tillage soils and 2 profiles shows that total S, total S, inorganic S, C-O-S, C S and C, S, S-C, S-C and S-C were respectively 94.8%, 5.2%, 54.8%, 5.7% and 35.1% , Respectively. There was a significant correlation between total S and total organic S and inert S, respectively. There was a significant correlation between total S and C-O-S. With the deepening of the profile, C-O-S, C-S and total organic S decreased the total S ratio, but the inert S and inorganic S increased gradually. Yellow soil texture coarse, organic C low, SO_4 ~ (2-) leaching serious, lack of S may.
