摘要: 本文采用气相色谱法同时测定了重金属Cd、As、Pb和Cu污染黑土中固氮菌及反硝化菌的作用强度。为准确、快速地提出土壤中Cd、As、Pb和Cu等重金属毒害土壤微生物临界指标开辟了新的途径。

Abstract: In this paper, the action intensity of nitrogen-fixing and denitrifying bacteria in chernozem polluted by heavy metals is determined with gas chromatographic method at the same time. An exact and fast new method for defining critical indicator of soil microorganisms polluted by heavy metals such as Cd, As, Pb and Cu is provided.
