| 摘 要： | 不同草甸植被下土壤有机质含量不同，同时腐殖质特性亦有较大差异。采用熊田法研究表明，不同类型的草甸土壤总腐殖质含量高低变化较大，总有机质含量变化在７．００％～１２．２８％之间，游离胡敏酸比率为５１．６７％～６０．１０％，游离富里酸比率为８０．０１％～８６．４６％；可提取腐殖质中胡敏酸所占经率为４７．９９％～５６．９８％。此外腐殖质相对色度、Ｅ４、也不明显差异。

| Abstract: | Soil orgarlic matter content was different in different meadow vegetation and humus property had obvious difference as well.The total humus content of the soil in different type of meadow varied considerably according to Tsutsukis method.The total organic matter content varied from 7.00% to 12.28%,the ratio of fHa/Ha was from 51.67% to60.10%,the ratio of fFa/Fa was from 80.01% to 86.46%,the rotio of extractable fHa in humus varied from 47.99% 56.98%.In addition,RF of humus and E 4 Had a significant different. |
