根据本文的初步研究,有如下的一些印象:(1)土壤有机质含量和粘粒含量的比值与干土块的总孔隙度呈良好的正相关;(2)无定形氧化硅和络合态铁与土块的抗压强度呈一定的负相关;(3)游离氧化铁为土壤中较为复杂的胶体物质,同土壤孔隙度和土块抗压强度间没有显示相关性;(4)松土的有机质在渍水还原后提供配位基的数量较多,且与有机质含量呈正相关,僵土的有机质则否。表明这两种物理性质不同的土壤,其有机质特性上也有差异。
According to the preliminary research in this paper, some impressions are as follows: (1) There is a positive correlation between the ratio of soil organic matter and clay content and the total porosity of dry soil; (2) Amorphous silica and complexation iron (3) The free iron oxide is a more complex colloidal substance in the soil, which shows no correlation with the soil porosity and the compressive strength of the clod. (4) Organic matter in the waterlogging reduction to provide a larger number of ligand, and the content of organic matter was positively correlated, soil organic matter is not. It shows that the two different physical properties of the soil, the organic characteristics are also different.
