| 摘 要： | 为了确定不同植物对复合污染底泥的修复效果,采用室外盆栽试验,比较了不同植物修复方式、互作条件下多酚氧化酶活性。结果表明:(1)植物-菌根真菌以及植物-菌根真菌-土著细菌联合修复方式,能够提高多酚氧化酶的活性,促进植物生长并吸收底泥中污染物;(2)玉米和黑麦草互作过程中,玉米-菌根真菌联合修复方式修复效果较好。黑麦草和紫花苜蓿互作过程中,黑麦草-菌根真菌修复方式的效果较好;(3)低温对酶活性影响较大。研究结论有助于确定复合污染底泥的最佳修复方式。

| Abstract: | In order to decide the repair effect of contaminated sewage river sediment by different plants,pot experiment was conducted.Under different phytoremediation method,activity change of polyphenol oxidase in sediment was inspected.Results showed that the phytoremediation method of plant-mycorrhizal fungi-native bacteria can increase the activity of polyphenol oxidase and improve the ability of plants to resist adverse environment.During the growth of maize-ryegrass interaction,the polyphenol oxidase of maize-m... |
