| 摘 要： | 土壤的有机质状况与成土条件之间有着紧密的联系。借助于腐殖质形成分析法,ТюРин确定了腐殖质形成过程的地带性规律。他指出,不同发生学土类,其腐殖质形成有着明显的不同1]。Кононова把土壤腐殖质看作为一个高分子物质体系,她证明成土条件对腐殖质的影响,不仅表现在分祖形成方面,而且也表现在胡敏酸的本性方面2]。另一方面,一些工作表明,有机厦状况的不同又将对土壤形成过程和土壤性质产生不同的影响3]。因此,研究土壤的腐殖质状况,不仅有助于对土壤性质的了解,而且可为成土过程,从而为土壤分类提供有益的资料。

| Abstract: | The composition of the humus of paddy soils developed under four different bioclimatic zones was studied. It is compared with the humus composition of corresponding soils under dry farming or/and under natural vegetation. Results obtained showed that both the humic acid/fulvic acid ratio and the degree of humification of humic acid decrease regularly in the following order: brown earth zone-yellow brown earth zone-red soil zone and lateritic soil zone. In the same bio-climatic zone, the humus of paddy soils is characterized with a higher humic acid/fulvic acid ratio and a lower degree of humification as compared with other soils. It was suggested that the water-logged condition of paddy soils favours the accumulation of humic acid but retards it form further condensation. |
