摘要:
从我国水稻主要种植区吉林松原(SY)、安徽安庆(AQ)、湖南邵阳(SHY)、浙江宁波(NB)和浙江温州(WZ)等地采集5种土壤,以日本宇都宫地区(YDG)土壤作对照,采用恒温培养法研究不同地区水稻土对磷的吸附与解吸特性及其可能的影响因素。结果表明,供试土壤的磷吸附等温曲线与Langmuir、Freundlich及Temkin等温吸附方程基本吻合,其中SY、NB和YDG土壤以Langmuir方程的拟合度最高,以单分子层吸附机制为主;AQ、SHY和WZ土壤以Freundlich方程的拟合度最高,以多层吸附机制为主。我国不同水稻土对磷的吸附性能从强到弱依次为AQ>WZ>SHY>SY>NB,对磷的解吸性能从强到弱依次为SY>NB>SHY>WZ>AQ;日本宇都宫地区的水稻土对磷的吸附容量远大于我国主要水稻种植区的土壤,而磷释放能力远小于我国的5种土壤,说明我国水稻土具有更大的磷素流失风险。
