指出了农药除蜗灵近年来的大量使用，对土壤环境质量产生了一定的影响，进行了其对土壤-植物根际微生物数量上的影响的试验，并设计了农药浓度和施药时间的不同，从而了解了农药除蜗灵对微生物的长远影响。为农药除蜗灵的施用时间、施用浓度及其对土壤环境质量的影响提供了一定的科学依据。通过采用倾注法分离土壤中微生物，利用平板计数法进行计数，可得知农药除蜗灵对土壤中微生物的影响如下：对细菌和放线菌都产生了明显的促进作用，而对霉菌产生了显著的抑制作用。随着时间的推移，农药除蜗灵对放线菌的增加作用最先减弱，霉菌次之，细菌最晚恢复，这又说明了土壤本身对农药具有一定的净化作用。

The agricultural chemical metaldehyde is widely used in recent years ,which has a certain influence on the soil environment's quality . This article has analyzed emphatically its impact on the soil - plant rhizosphere microorganism's amount ,and has designed the different agricultural chemical's concentration and application time to test agricultural chemical metaldehyde's long -term influence on microorganism ,which provides a scientific basis for agricultural chemical metaldehyde's application time , application concentration and impact on soil environment's quality .The tilt-pour process separates microorganism in the soil and ,plate count method counts the amount ,then the article have found ,the impact of agricultural chemical metaldehyde on edaphon are as follow s:the agricultural chemical metaldehyde plays an auxo-action to bacteria and actinomycetes ,but plays an inhibitory action to mycete . As time passes by ,the agricultural chemical Metaldehyde's increase function to actinomycetes decreases first ,then follows mycete and the bacteria's recover is the latest .The test results also explains that the soil itself has certain purification effect to the agricultural chemicals .
