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40mg·kg-1 Cd2+的处理与对照差异极显著。
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.
