| 摘 要： | 对长江冲积土壤硫进行了分析，结果表明：１．从无为县开始沿江而上至宿松县，长江冲积土壤有效Ｓ有减少的趋势。２．从平均值来看，水稻土有效Ｓ大于灰潮土；潜育型水稻土大于潴育型水稻土。３．灰潮土有效Ｓ含量不高，但潜在供Ｓ能力较强。Ｃ－Ｏ－Ｓ是主要潜在硫库，其次是惰性Ｓ和难溶Ｓ。

| Abstract: | The result of analysing 67 samples of alluvial deposit Soil from Yangtze river showed:1.Available sulfur content of soil was getting lower and lower from Wuwei county to Susong county.2.Available Sulfur content of paddy soils was higher than that of Grey meadow;available sulfur content of Gleyed Paddy soil was higher than that of Stagnating.3.Available sulfur content of Grey meadow was low,but potential capacity of sulfur supplyment was strong,the majority which was c o s;the second,inert s and the tast, slowly soluble sulfur. |
