摘要:
利用生物量高的经济作物进行轮作,可在加快修复土壤Cd污染进程的同时获得一定的经济效益.本研究在长沙市望城区群力村Cd轻度污染的土壤进行冬季种植红叶甜菜、夏季复种植花生和春末种植油葵、夏季复种植花生的轮作模式试验,探究重金属修复潜力.结果表明:花生、油葵、红叶甜菜各部位Cd富集系数除花生果实外均大于1,对Cd均有较强的富集能力.油葵-花生、红叶甜菜-花生轮作模式种植一季可提取土壤Cd总量分别为40.80 g·hm-2和53.34 g·hm-2.红叶甜菜-花生轮作将土壤Cd含量由0.316 mg·kg-1降至0.286 mg·kg-1,油葵-花生轮作一季将土壤Cd含量由0.316 mg·kg-1降至0.283 mg·kg-1.研究表明,红叶甜菜-花...
摘要(英文):
Rotation of cash crops with large biomass can accelerate the process of soil Cd pollution remediation and achieve certain econom⁃ ic benefits. In this study, two plant rotation patterns were carried out in soil mildly contaminated with Cd(Qunli Village, Wangcheng Dis⁃ trict, Changsha City, China)to explore their remediation potential for heavy metal pollution in soil. The red leaf beet and peanuts were grown in winter and summer, respectively, for the first pattern and the oil sunflower and peanuts were planted in late spring and summer, re...
