分析测定了A,B,C 3种不同农用腐植酸的主要组分及基本理化性质,结果表明:A,B 2种腐植酸总含量为91.84%~96.62%,而C腐植酸总含量仅74.79%;3种腐植酸的组分中均以黑腐酸为主,占77.3%~93.7%,黄腐酸含量均小于1%;A,B 2种腐植酸为酸性,容重,阳离子交换量和交换性钾含量等性质都比较接近,C腐植酸呈碱性,阳离子交换量和交换性钾含量明显大于A,B 2种,适于烟草等喜钾作物;3种腐植酸的含碳系数非常接近

The main compositions and basic physical and chemical properties of A,B,C,three different agricultural humic-acid-containing fertilizers,were analyzed and determined.The results showed that the total contents of humic acid in A and B are between 91.84% and 96.62%,while the content of humic acid in C is 74.79%;the main composition of the three agricultural humic-acid-containing fertilizers is humin,whose content can reach 77.3%~93.7%,and the content of fulvic acid is less than 1%;the properties of A and B are similar in bulk density,pH value（pH...
