| 水稻土 paday soil 长期种植水稻形成的具有氧化还原交替特点的耕作土壤。长期植稻引起土壤有机质含量增加，有机质组成趋于简单；饱和土壤中盐基淋溶，不饱和土壤发生复盐基作用；铁、锰元素在土壤中移动，耕层含量较低，淀积层较高，潜育层最低；粘粒矿物发生分解和合成。随着水稻土形成作用的发展，出现水稻土特有的发生层：耕作层、犁底层、淀积或斑纹层、漂洗层、潜育层。水稻土分布极广，凡气候适宜又有水源灌溉的土壤均可经种植水稻而形成。主要分布在北纬35°至南纬23°之间，以亚洲最多。中国集中在长江下游平原、四川盆地、珠江三角洲和台湾西部平原。水稻土的类型主要有：①淹育性水稻土。多分布在丘陵，地下水位低，耕层浅，肥力不高。②潴育性水稻土。分布于冲积平原，地下水位一般60～150厘米，土壤通透性好，矿质养分丰富，肥力高。③潜育性水稻土。分布在丘陵谷地或冲积平原洼地，土质轻粘，有的有泥核，耕作困难，有效养分低，尤磷、钾不足。④漂洗型水稻土。在下降水或侧渗水影响下形成，土层紧实，通透性差，有机质含量低，养分贫乏。高产水稻土应是耕层深厚，犁底层不太紧实，通气透水，质地适中，耕性良好，水渗透快慢适度，养分供应协调。
