  • 摘要: 用土壤薄层色谱法研究农药丙溴磷在不同层江西省稻田红壤中的移动特性及其在表层土壤中移动的主要影响因素.以稻田灌溉水为展开剂，测得丙溴磷在表、中和下层土壤薄层板上的比移值Rf分别为0.375、0.301和0.092，这表明丙溴磷在表层土壤中中等移动、中层土壤中不易移动和下层土壤中不移动，对地下水污染可能性较小，但可能对地表水会产生一定程度的污染.改变土壤有机质和黏土量，调节稻田灌溉水pH和CEC（阳离子交换量），考察这4种因素对丙溴磷在表层稻田红壤中移动的影响.结果表明，土壤有机质可抑制表层土壤中丙溴磷的移动，但起主要抑制作用的是难氧化土壤有机质；土壤黏土量与丙溴磷在土壤中的移动性呈明显的负相关，其相关系数为-0.976（n=5，P5时，表层红壤中丙溴磷的迁移随pH增大而增大；增大稻田灌溉水的CEC可促进丙溴磷在表层土壤中的移动.从同一土壤剖面来看，稻田红壤CEC和黏土量是丙溴磷在不同层土壤中移动性差异的主要影响因素.
    Abstract: The transport of profenofos in different layers of red paddy soil of Jingxi Province and its main influence factors in topsoil were studied by thin layer chromatography (TLC). With paddy irrigation water as spread solution, the Rf values of profenofos in topsoil, middle soil and subsoil thin layer plate were 0.375, 0.301 and 0.092, respectively, which indicated profenofos was moderately mobile in topsoil, not easy to move in middle soil and difficult to move in subsoil. It also suggested profenofos was less likely to pollute groundwater, but may pollute surface water. To investigate the influence factors of mobile behavior of profenofos in red paddy soil, the amount of soil organic matter (SOM) and clay were changed, the pH and CEC (cation exchange capacity) of paddy irrigation water were adjusted. The results of soil TLC showed that SOM inhibited the movement of profenofos in topsoil, but the SOM which can be oxidized easily had smaller inhibition than those which are difficult to oxidize. There was a significant negative correlation between the content of clay minerals and the mobility of profenofos in soil, with correlation coefficient -0.976 (n=5, P<0.05). When the pH of paddy irrigation water was larger than 5,the transport of profenofos in top red paddy soil increased with pH and CEC of paddy irrigation water. In general, CEC of irrigation water and clay content of red paddy soil are the main influence factors of profenofos transport in different layers of this soil.
