The soil organo - mineral complexes, formed by intimate association of organic matters or humic substances and mineral, is one of the fundamental features that distinguishes soils from their geological parent materials, and effects on the nature of soil aggregate, and the amounts and characters of soil particle aggregation is closely related to soil fertility. by way of collecting soil samples outdoors and analysis indoors and using the dry land soils developed from purple soils as research materials, this paper investigated status of organo - mineral complexion, characters of aggregation and soil fertility for discussing the relationship among them under different land treatments, and the factors that influencing the amounts and characters of organo - mineral complexion and soil aggregation and restricting status of soil fertility, the main results were as follows : there were remarkable differences of status and activity of fe oxide and aluminum oxide in dry land soils developed from different parent soils and under different utilizations
土壤中有機物質和礦物質的結合?土壤有機無機復合體是土壤區別其母質的基本特徵之一，它對土壤團聚體的性質有很大的影響，而團聚體的數量和性狀有跟土壤肥力密切相關，本文以不同母巖發育的旱地紫色土作為研究材料，通過野外采樣和室內分析，研究了旱地紫色土的有機無機復合狀況、團聚體特徵和肥力水平，探討了在不同土地利用方式下它們之間的關系，以及影響有機無機復合、土壤中團聚體的數量、性質以及制約土壤養分狀況的因素，主要結果如下：不同類型的紫色土鐵鋁氧化物形態和活性具有很大差別。 -
By using the soil samples prepared with different dry density and water content, a great amount of instant vibration test is performed and the signals of acceleration and force are acquired
