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洋葱生产的影响。结果表明,随着活化钢渣施用量的增加,洋葱产量先增加后减少,而单独施用钢渣洋葱产量有所下降,单独施用风化煤洋葱产量有所增加;钢渣作为微量元素肥料可明显提高洋葱中Vc、可溶性固形物、硅、硫等的含量,每公顷施用2 250 kg的钢渣可以明显降低洋葱长芽与腐烂的比例,便于贮藏;另外,钢渣中重金属铬含量较高,随着施用量的增加,表层土壤中铬含量增加,当钢渣施用量为3 000 kg/hm2时,不会对土壤和粮食造成污染。Effect of slag used on onion 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 onion increased first and then decreased, and application of steel slag onion yield fell alone, single application of weathered coal onion yield increased. Steel slag as a trace element fer- tilizer can obviously increase the content of Ve in onions, the soluble solids, silicon, sulfur, when the steel slag application of 2 250 kg per hectare can obviously reduce the onion long shoots and decay ratio, convenient storage. In addition, heavy metal chromium content in steel slag was high, as seems to increase, the chromium content in the surface soil increased, when applying steel slag content of 3 000 kg/hm2, wouldn＇t cause pollution to soil and food.
