- 摘要:
- 以多年生黑麦草为试材，采用连续浇灌的方法，研究了3%、6%、9%电解锰渣液对多年生黑麦草株高度、光合色素、可溶性糖、脯氨酸含量变化的影响，以期为电解锰渣污染场地的修复提供理论参考。结果表明：3%电解锰渣液对黑麦草生长的抑制作用不明显，而6%、9%电解锰渣液对黑麦草生长有极显著抑制作用，6%、9%电解锰渣液处理12 d，总叶绿素含量分别较对照显著下降了47.50%、70.87%；类胡萝卜素含量分别较对照显著下降了77.80%、83.90%。多年生黑麦草对3%电解锰渣液有一定的耐受性，具有修复锰渣污染产地的修复潜力。
- Abstract:
- Taking perennial ryegrass as test photosynthetic materials,the effects of 3%,6% and 9% electrolytic manganese residue solution on plant height,pigments,soluble sugar and proline content of perennial ryegrass were studied by continuous irrigation method in order to provide theoretical reference for remediation of electrolytic manganese residue contaminated sites.The results showed that the inhibition of 3% electrolytic manganese slag solution on ryegrass growth was not obvious,while 6% and 9% electrolytic manganese slag solution had significant inhibition on ryegrass growth.After 12 days of treatment with 6% and 9% electrolytic manganese slag solution,the total chlorophyll content decreased by 47.5% and 70.87% respectively,and the carotenoid content decreased by 77.80% and 83.90% compared with the control.Perennial ryegrass has a certain tolerance to 3% electrolytic manganese slag,and has the potential of remediation of manganese slag contaminated areas.
