摘　　要：在山西省主要类型的石灰性褐土上,通过大田试验研究农田施用钢渣对玉米生产的影响。结果表明,随着活化钢渣施用量的增加,玉米产量先增加后减少,而单独施用钢渣玉米产量最高,单施风化煤玉米产量有所下降;钢渣作为硅肥可明显提高玉米籽粒中硅的含量;另外,钢渣中重金属Cr含量高,随着施用量增加,表层土壤中Cr含量增加,当钢渣施用量不超过3 000 kg/hm2时,不会对土壤和粮食造成污染。Effect of steel slag used on corn in major calcareous cinnamon soil of Shanxi province was studied by field experiment.The results showed that, with the increase of activation of steel slag application rate, the yield of corn increased first and then decreased,and application of steel slag corn yield was the highest alone,fertilization of weathered coal corn yield fell. Steel slag as silicon fertilizer could obviously increase of silicon content in corn grains. In addition,heavy metal chromium content in steel slag was high, as seems to increase,the chromium content in the surface soil increased. When the steel slag application amount didn＇t exceed 3 000 kg/hm^2, it would not cause pollution of soil and grain.
