摘要
１９９６～１９９８年，在太原市南郊区严重重金属污染的农田上进行了小麦抗重金属污染栽培试验。种子经过稀土处理，各处理产量比对照平均提高１４０％；蛋白质含量比对照提高８１％～１７４％；子粒中Ｈｇ，Ｃｄ与Ａｓ含量分别下降６３３％～９８０％，３８５％～１００％，２２８％～７９２％。用等级聚合方法将１２个处理分为两组，１１个处理均明显优于对照，可直接用于生产。
The field culture experiment of anti-heavy metal pollution of wheat was conducted for three years in the fields polluted badly by factories in the south suburb of Taiyuan. The seeds were treated with rare earth (R.E.) befor sowing in Autumn. Compared with the CK, the plot output increased 14.0% averagely, the content of protein increased 8.1%～17.4%. The Hg, Cd and As was reduced 63.3%～98.0%, 38.5%～100%, 22.8%～79.2% respectively. The 12 treatments can be divided to two groups with hierarchical agglomeration. The 11 treatments are better than CK obviously, and they can be used in production directly.
