【摘要】 1996－1997年，在太原市南郊区严重污染农田上进行了番茄抗重金属污染栽培试验。种子经过稀土处理，各处理产量比对照提高12．9％～29．4％；维生素C含量比对照提高24．2％～52．5％；果实中Hg，Cr与Cd含量分别下降36．0％～86．0％，45．3％～50．8％，7．4％～55．6％。用等级聚合方法将处理分为两组，4个处理均明显优于对照，可直接用于生产更多还原

【Abstract】 The field culture experiment of anti - heavy metal pollution of tomato was conducted for two years in the fields polluted badly by factories in the south suburb of Taiyuan. The seeds were treated with rare earth (R. E. ). Compared with the CK, the tomato output increased 12.9% ～29.4%, the content of vitamin C increased 24. 2% ～ 52 .5%. The content of Hg, Cr and Cd was reduced 36.0% ～ 86.0%,45. 3% ～ 50.8%, 7 .4% ～55. 6% respectively. The heatments can be divided to two groups with hierarchical agglomeration. The four heatments are better than CK obviously and they can be used in production directly.更多还原
