| 摘 要： | 本文利用示踪技术研究多效唑在３种土壤中的行为。土壤理化性质对多效唑在土壤中的纵向移动和横向扩散有影响。多效唑在土壤中的纵向移动性较大，且随时间的推移纵向移动性减小．多数唑易被土壤吸附，但仍有部分易随雨水横向扩散和纵向移动。土壤对多效唑的吸附量随浓度增加而提高，在一定浓度范围内，浓度对吸附率的影响不大。

| 关 键 词： | 多效唑，纵向移动，横向扩散，吸附量，吸附率 |

| Abstract: | This article studied behaviour of paclobutrazol in theree kinds soil with labelled technol-ogy.Effect of physicocemieal character of soil on vertical move and crossiwise spread of Paclobu-trazol in soil. Its vertical move was greater and decreased with the lapse of time in soil. Paclobu-trazol was easy absorpted by soil,but part of Paclobutrazol was easy crossiwise spreadcd and ver-tical moved by rain-water.Absorption dose of soil on Paclobutrazol was up with increasing con-centration,concentration effect on absorption rate was very little in specified concentrationrange. |

| Keywords: | paclobutrazol vertical move crossiwise spread absorption dose absorption rate |
