摘　　要：以京冠3号为试材,采用盆栽试验方法,研究了甜菊糖提取液、聚谷氨酸发酵液和玉米浆提取液对镉(Cd)污染土壤上普通白菜生长和Cd积累的影响。结果表明,与对照相比,施用1 g·kg^(-1)玉米浆提取液能够显著提高普通白菜地上部鲜质量,比对照增加了61.11%;显著降低地上部镉含量,比对照降低了15.97%;生物富集系数也显著降低。施用1 g·kg^(-1)聚谷氨酸发酵液亦表现促进作用,地上部鲜质量增加,地上部镉含量和生物富集系数降低,但均与对照差异不显著。施用1g·kg^(-1)甜菊糖提取液则表现为抑制作用,地上部鲜质量显著降低,且地上部镉含量和生物富集系数明显增加。综上,玉米浆提取液处理有利于保证普通白菜的安全生产,在资源高效利用方面具有较好的应用潜力。The effects of stevioside extract,polyglutamic acid fermentation broth and corn steep liquor extract on the growth and cadmium(Cd)accumulation of pakchoi‘Jingguan No.3’in the Cd-contaminated soil were studied by pot experiment.The experimental results showed that compared with the control,applying 1 g·kg^(-1) corn steep liquor significantly increased the fresh weight above ground of pakchoi by 61.11%,and significantly reduced the Cd content above ground of pakchoi by 15.97%.The bioconcentration factor also decreased significantly.The application of 1 g·kg^(-1) polyglutamic acid fermentation broth also showed the promoting effect,which increased the fresh weight above ground of pakchoi,decreased Cd content and bioconcentration factor above ground of pakchoi,but there was no significant difference compared with the control.Application of 1 g·kg^(-1) stevioside extract exhibited inhibitory effects,which significantly reduced the fresh weight above ground of pakchoi,significantly increase Cd content and bioconcentration factor above ground of pakchoi.In summary,the use of corn steep liquor can enhance the safety of pakchoi production and has significant potential for resource efficiency.
