| 摘 要： | 为促进马铃薯生产，试验以早熟马铃薯品种费鸟瑞它为试材，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Cd^2＋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40mg·kg^-1Cd^2＋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 po- tato decreased significantly, dry-weight, proportion, dry matter accumulation rate and content of starch de- creased significantly extremely. Mild cadmium pollution had little effect on content of protein,only treatment of 40 mg,kg~Cdz＋ had significant difference than control. |
