本文是土壤肥力实质研究的一部分。对红壤的研究再一次地证明,土壤腐殖物质的形态特征、组分含量、以及各级微团聚体的数量分配深刻地影响着土壤的体质与体型。红壤的肥力基础物质的构成特点和作用机理,在一定程度上与土壤中较高含量的游离氧化铁及其在各粒级微团聚体中的分配不同有关。
This article is part of an in-depth study of soil fertility. The study of red soil once again proves that the morphological characteristics of humus, the content of soil components and the distribution of micro-aggregates at various levels have a profound impact on soil physique and body shape. The compositional characteristics and mechanism of the fertility base material in red soils are to some extent related to the higher content of free iron oxide in the soil and its distribution in the microaggregates of each size fraction.
