| 摘 要： | 目的]通过研究草铵膦和草甘膦对土壤微生物种群及酶活性的影响,为评价2种除草剂对土壤生态环境效应的差异提供参考。方法]采用室内培养法研究土壤细菌、真菌、放线菌种群数量及土壤脲酶、酸性磷酸酶和酸性转化酶活性对50~500 mg/kg 5种不同质量分数草铵膦和草甘膦的胁迫响应。结果]草铵膦和草甘膦对土壤细菌和放线菌种群的生长表现为低剂量促进高浓度抑制;对土壤真菌种群的生长表现为抑制作用;对土壤脲酶和酸性磷酸酶活性也表现为抑制作用,且随药剂剂量提高逐渐增强;对土壤酸性转化酶活性草铵膦表现为低剂量促进高剂量抑制,草甘膦表现为随药剂剂量提高促进作用逐渐增强。结论]土壤可培养细菌、真菌、放线菌,脲酶、酸性磷酸酶、酸性转化酶对2种除草剂胁迫的响应均表现为草铵膦敏感于草甘膦。
