水稻土引人注目的形态特点是呈花斑状,这种形态特征是在基质色调的背景上由铁锰斑点,灰色胶膜与潜育斑镶嵌而成的。在进行水稻土剖面观察时,从远处看基本上是灰色或灰棕色色调,而在近处仔细观察,则不难看出在底色的背景上穿插着纵横交错的杂色斑纹。其镶嵌程度要比相应的起源土壤细致得多。这种形态特征,无疑同水稻土的形成特点有关系。 The striking morphological feature of paddy soils is the appearance of a flower patch. This morphological feature is inlaid with iron-manganese spots, a gray film and a latent spot on the background of the substrate color. During the observation of the paddy soil profile, when viewed from a distance, it is basically a shade of gray or beige. When closely observed in the vicinity, it is not difficult to see that mottled variegated stripes crisscross the background of the background. The extent of its mosaic than the corresponding origin of the soil much more meticulous. This morphological feature is undoubtedly related to the formation of paddy soil.
