%X The study with rhizobag showed that in celery rhizophere and non-rhizosphere soil, metolachlor had a certain inhibitory effect on catalase activity, but stimulated dehydrogenase activity. Generally, the enzyme activities in rhizosphere soil were higher than those in non-rhizosphere soil. After 45 days of metolachlor treatment, the numbers of bacteria and fungi in rhizosphere soil were higher than those in non-rhizosphere soil, and the R/S was 1.76 to approximately 2. 51. The numbers of actinomycetes were relatively stable, and the rhizosphere effect was not significant. The degradation rate of metolachlor in rhizosphere and nonrhizosphere soil was 0. 0217 and 0.0176, and the corresponding half-live was 31.9 and 39.4 days, respectively. The degradation of metolachlor was enhanced greatly in rhizosphere soil.
