本文通过含有不同浓度的铜、铅、砷、镉 4种重金属的大豆、小麦盆栽试验 ,采用气相色谱方法测定土壤微生物酶活性 .结果表明 :低浓度的重金属能够提高固氮酶和反硝化酶的活性 ,而高浓度的重金属对上述二种酶有强烈的抑制作用
In this paper, soil microbial enzyme activity was determined by gas chromatography with soybean and wheat containing four heavy metals including copper, lead, arsenic and cadmium at different concentrations.The results showed that low concentrations of heavy metals could increase the activity of nitrogenase and denitrifier , While high concentrations of heavy metals on the two enzymes have a strong inhibitory effect
