通过对淮南市潘集区6个乡镇0～20cm耕层土壤采取的1044个样品中速效态钾、缓效态钾和全量钾的分析测定，研究各形态钾的含量特点及其相互关系。结果表明，6个乡镇的1044个样品中土壤速效K含量的平均值为131.13mg/kg，根据我国土壤肥力标准指标可以确定6个乡镇的土壤速效钾含量属于中等水平，但各乡镇之间土壤速效钾的空间分布不均匀，变异系数在43.17%，变异较大；缓效钾的平均值在474.41mg/kg，全钾的平均值为18.13g/kg，两者的含量在全国范围内也处在中等水平。以SPSS软件对三者之间的关系作统计分析显示：速效钾和缓效钾、全钾皆成低度相关关系，但速效钾与缓效钾的相关性要高于全钾；缓效钾与全钾成中度相关关系。

Through analysis and mensuration of available kalium,slow-release kalium and total kalium in 1044 soil samples taken from 0~20cm farmland topsoil of six villages in Panji District,Huainan City,the content feature and relativity of different forms of kalium has been studied. The Results showed:the aver-age content of available kalium is 131.13mg/kg which is of middle level according to the standard of soil fertility index. However,the space distribution of available kalium contents are not even,the coefficient of variation is 43.17%. The average contents of slow-release kalium and total kalium are 474.41mg/kg and 18.13g/kg separately which are all of middle level. Correlation analysis through SPSS showed that the con-tents of available kalium have low correlation with slow-release kalium and total kalium,however slow-re-lease kalium has a higher correlation with available kalium than total kalium. Slow-release kalium have middle collation with total kalium.
