摘　　要：以瑞飞特为材料,考察不同浓度瑞飞特对土壤微生物及土壤酶活性的影响。结果表明,当瑞飞特质量分数为0.0004%和0.004%时,能促进土壤中细菌、放线菌、固氮菌的生长及土壤脲酶、蛋白酶、蔗糖酶、过氧化氢酶活性,但也抑制真菌生长;当质量分数达到0.04%时,会抑制细菌、真菌、放线菌、固氮菌的生长及壤脲酶、蛋白酶、蔗糖酶、过氧化氢酶的活性。In order to study the effect of soil microbe and soil enzyme activity by different concentration of pretilachlor, pretilachlor was used to treat the rice paddy. The results showed that the growth of bacteria, actinomycete, rhizibia, azotobacter and the activity of urease, protease, sucrase, catelase were enhanced when the concentration of pretilachlor was 0.000 4% and 0.004%, while the growth of fungi was inhibited, when the concentration of pretilachlor was 0.04%, the growth of bacteria, fungi, actinomycete, rhizibia, azotobacter and the activity of urease, protease, sucrase, catelase were all inhibited.
