| 摘 要： | 赣中丘陵地区广泛分布着由第四纪红土发育的水稻土,它是重要的产粮地区,也是低产田分布较广的地区。提高低产的红壤性水稻土的肥力,一向是大家所关心的问题,各有关单位做了不少的研究。关于红壤性水稻土的结构特性及胶结物质等曾有研究1,9],但对结构形成具有重要意义的微团聚体的特性及其与农业措施的关系,研究较少。土壤微团聚体质和量的研究,可分别土壤肥力的高低,也可阐明輪作、耕作和施肥等措施在培肥中的作用。作者4,6]曾进行中性水稻土有机矿质复合体的研究,在此基础上,本文拟就红壤性水稻土中微团聚体1)的特性及其与土壤肥力的关系作一初步了解,为进一步开展这方面的研究提供线索。

| Abstract: | Three groups of micro-aggregate, including water dispersed (G0,sodium dispersed (G1) and mechanical-sodium dispersed micro-aggregate (G2),were separated by the peptization method from three groups of paddy soil derived from Quarternary red clay. The total amounts of micro-aggregates are 54, 58, 60% based on air-dry soil and the ratio of G0+G1:G2 are 0.45, 0.94, 1.46 respectively. |
