为研究咪唑烟酸在耕地土壤中的降解情况，通过试验分析咪唑烟酸在潮土、褐土以及紫泥土的降解半衰期。结果表明：潮土的降解半衰期最大（降解速率最慢），而紫泥土的半衰期最短（降解速率最快）。降解半衰期与土壤各性质之间的回归分析表明：影响咪唑烟酸在土壤中降解的主要因素为有机质含量，其次为土壤酸碱度。

In order to study the degradation of the imazapyr in farmland soil,the degradation half-life period of imazapyr in alluvial soil,cinnamon soil and purple soil were analyzed by experiment.The results showed that the degradation rate of alluvial soil was slowest and that of purple soil was fastest. Regression analysis between the degradation half-life period and soil properties indicated that the quantity of organic matter was the most important factor among all influencing factors and the pH of the farmland soil was the secondary factor.
