研究了多菌灵和氯霉素单用和混配后在土壤中的消解动态及其对土壤真菌细菌比和土壤酶活性的影响。结果表明，氯霉素对多菌灵的消散影响不大，而多菌灵的存在则显著延缓了氯霉素的消散。多菌灵对真菌：细菌比的抑制作用通过氯霉素的存在而增加，并且氯霉素对中性磷酸酶的抑制作用通过多菌灵的存在而增加。多菌灵增加土壤过氧化氢酶和脲酶活性，但氯霉素的存在部分减弱了这种增加。多菌灵和氯霉素对土壤转化酶的影响无交互作用。本研究结果表明，杀菌剂和抗生素的组合可能会改变化合物在土壤中的个体行为及其对土壤酶的影响。
The dissipation of carbendazim and chloramphenicol alone and in combination and their effects on soil fungal:bacterial ratios and soil enzyme activities were investigated. The results revealed that carbendazim dissipation was little affected by chloramphenicol, whereas chloramphenicol dissipation was found to be retarded significantly by the presence of carbendazim. The inhibitory effect of carbendazim on the fungal:bacterial ratios was increased by the presence of chloramphenicol, and the inhibitory effect of chloramphenicol on neutral phosphatase was increased by the presence of carbendazim. Carbendazim increased soil catalase and urease activities, but this increase was partially diminished by the presence of chloramphenicol. Little interaction was observed between carbendazim and chloramphenicol with regard to their influence on soil invertase. The results obtained in this study suggest that combinations of fungicides and antibiotics may alter the compounds’ individual behaviors in soil and their effects on soil enzymes.
