| 中文摘要: |
| 通过土培实验研究了啶酰菌胺对酸性紫色土脲酶、硝酸还原酶、亚硝酸还原酶及脱氢酶活性的影响。结果表明,各浓度处理下在培养第7 d对脲酶、硝酸还原酶、亚硝酸还原酶及脱氢酶活性影响显著(P<0.05).随培养时间延长,10 mg·kg-1处理下,酶活性与CK差异不显著,50 mg·kg-1浓度处理下,除脱氢酶外,其余酶活性在培养期内能恢复正常水平;100 mg·kg-1浓度处理下,亚硝酸还原酶表现出“抑制-恢复-激活”,脲酶、硝酸还原酶及脱氢酶活性在培养期内均表现出抑制;200 mg·kg-1浓度处理下,四种酶在培养期内均受到显著抑制。相关分析结果表明,脲酶与硝酸还原酶活性显著正相关,与亚硝酸还原酶、脱氢酶活性极显著正相关,硝酸还原酶与脱氢酶活性极显著正相关。 |
| 英文摘要: |
| This paper studied the effects of boscalid on urease, nitrate reductase, nitrite reductase and dehydrogenase in acid purple soil in a pot experiment. Results showed that activites of all enzymes in soil treated with boscalid ranged from 10 to 200 mg·kg-1 and were significantly affected on day 7 after boscalid treatments. In 10 mg·kg-1 boscalid-treated soil, all enzyme activities were not markedly different from the control from 14~42 days. In 50 mg·kg-1 treatment, soil enzyme activities resumed normal levels during 14~42 th day, with an exception of dehydrogenase. In 100 mg·kg-1 treatment, however, nitrite reductase displayed “inhibition-recovery-stimulation”; while urease, nitrate reductase and dehydrogenase activities were inhibited during the experimental period. In 200 mg·kg-1 soil, the activites of four enzymes were notably inhibited during the experimental period. Urease had significant and positive correlation with nitrate reductase, nitrite reductase and dehydrogenase. Significant and positive correlationship was found between nitrate reductase and dehydrogenase. |
