| 摘 要： | 通过盆栽实验,系统研究了含羞草、白雪姬和树马齿苋对Cd污染土壤中土壤酶的修复作用。结果表明,脲酶、过氧化氢酶和磷酸酶的活性随着Cd浓度的上升不断下降,且均与Cd浓度呈显著负相关关系。3种观赏植物生长均能提高Cd污染土壤中脲酶、磷酸酶和过氧化氢酶的活性。白雪姬还能显著提高土壤蔗糖酶的活性。含羞草、白雪姬和树马齿苋对土壤酶的修复效果均表现为:脲酶>磷酸酶>过氧化氢酶>蔗糖酶,且白雪姬对土壤酶的修复效果显著高于其它两种观赏植物,说明白雪姬作为一种常见的观赏植物,在修复重金属Cd污染土壤方面具有很高的应用前景。

| Abstract: | Effects of the growth of Mimosa pudica,Tradescantia sillamontana and Porulaca afra on soil enzyme activities of cadmium contaminated soils were studied by pot experiment.The results showed that soil urease,catalase and polyphenol oxidase activities decreased gradually with the increase of Cd concentration.There was a significant negative correlation between Cd concentration and soil enzyme activities.With the seedlings growth of these three kinds of ornamental,the activities of urease,catalase and polypheno... |
