摘  要：
通过盆栽试验,研究了氮镉交互作用对苋菜土壤酶活性的影响。结果表明,在试验范围内,在不施氮的情况下,一定浓度的镉污染促进了蔗糖酶和蛋白酶活性,而抑制了脲酶活性,酸性磷酸酶的活性在0～1.0mg/kg范围内不受镉污染的影响;在不加镉的情况下,蔗糖酶和酸性磷酸酶的活性分别在0.2g/kg和0.4g/kg的氮素水平时达最大,且与其他处理差异显著,脲酶的活性随氮素营养的增加显著降低,而蛋白酶的活性随氮素营养的增加显著增加;在镉氮交互作用下,对4种酶的活性都有显著影响,对蛋白酶的活性影响最大,其次是脲酶,然后是蔗糖酶,对酸性磷酸酶的活性影响最小。

摘  要：
A pot experiment was conducted to study interactive effects of nitrogen application and cadmium contamination on soil enzyme activities. The results showed low level cadmium pollution could promotion the acticity of the Sucrase and Protease and inhibit Urease activity. In no case of cadmium, activity of Sucrase and Acid Phosphatase were the largest in the 0.2 g/kg and 0.4 g/kg Nitrogen levels. And there had significant differences with other treatments. Urease activity reduced significantly with the increase of nitrogen nutrition. Protease activity increased significantly with the increase of nitrogen nutrition. In the interaction effects of nitrogen and cadmium, four kinds soil enzymes activity had a significant effect.
