- 摘要:
- 为促进马铃薯生产，试验以早熟马铃薯品种费乌瑞它为试材，采用盆栽方式，研究了土壤中不同浓度镉处理对马铃薯块茎产量及品质的影响。结果表明：不同浓度镉处理对马铃薯块茎的产量和品质均有影响。随着Cd2+浓度的增加，马铃薯块茎鲜重显著降低，干重、比重、干物质积累率及淀粉含量极显著降低，土壤轻度镉污染对马铃薯蛋白含量影响不大，只有添加40 mg.kg-1Cd2+的处理与对照差异极显著。
- Abstract:
- In order to promote the potato production，the effect of cadmium concentration on fresh-weight,dry-weight,proportion,dry matter accumulation rate,content of protein and starch of potato tuber were studied with pot experiment.The results showed that with the increasing of cadmium concentration,fresh-weight of potato decreased significantly,dry-weight,proportion,dry matter accumulation rate and content of starch decreased significantly extremely. Mild cadmium pollution had little effect on content of protein，only treatment of 40 mg?kg-1Cd2+ had significant difference than control.
