Soil pollution with heavy metals and iron (Fe) malnutrition is big concern of industrial areas in arid and semi-arid regions. We studied the potential of Fe-enriched green manures application and Piriformospora indica (P.indica) to increase grain Fe concentration of two bread wheat genotypes differing in Fe efficiency (Triticum aestivum L. cvs. Falat, and Durum) in a Pb-polluted soil. To prepare Fe-enriched green manures sunflower, corn, and canola were cultivated in the soils treated with 0%, 0.5%, 1% and 1.5% (W/W) of iron slag, converter slag, and elemental sulfur. After 70 days, the plants were harvested and the Fe concentration in their biomass was measured. The plants grown in 1.5% elemental sulfur were selected as green manures due to their higher Fe concentration than those grown in soils treated with other industrial byproducts studied. Application of sunflower residues and presence of P. indica in Pb-polluted soil increased the grain Fe concentration of Falat and Durum wheat genotypes from 48.8 to 132.7 and 40.2 to 118.8 mg kg⁻¹, respectively. The response of wheat plants to the presence of P. indica and green manure application was significantly affected by the wheat genotype. Application of sunflower residues increased soil microbial respiration and dissolved organic carbon which was consistently magnified by the presence of P. indica. This study showed that agricultural management, including the use of Fe-enriched green manure, could be asuitable method to increase Fe concentration and reduce Pb concentration in wheat grains grown in Pb-polluted soils of arid and semi-arid regions.

重金属和铁（Fe）营养不良造成的土壤污染是干旱和半干旱地区工业区的主要关注点。我们研究了富铁绿肥和印度梨梨（P.formica）的应用潜力，可提高两种不同铁效率的不同基因型面包小麦的籽粒铁浓度（小麦）L.简历 Falat和Durum）在受Pb污染的土壤中。为了制备富铁的绿肥，在用0％，0.5％，1％和1.5％（W / W）的铁渣，转炉渣和元素硫处理的土壤中种植向日葵，玉米和油菜。70天后，收获植物并测量其生物量中的Fe浓度。选择生长在1.5％元素硫中的植物作为绿肥，因为它们的铁含量比用其他工业副产品处理过的土壤中的铁更高。向日葵残留物的施用和铅污染土壤中的印度。病的存在使Falat和Durum小麦基因型的籽粒铁浓度从48.8 mg / kg升高到132.7 mg / kg和-18.8 mg kg ^-1。， 分别。小麦的基因型显着影响了小麦植物对in稻和绿肥施用的反应。向日葵残留物的施用增加了土壤微生物的呼吸作用和溶解的有机碳，而印度。的存在一直使这种有机碳不断增加。这项研究表明，在干旱和半干旱地区，Pb污染土壤中种植的小麦籽粒中，农业管理（包括使用富含Fe的绿肥）可能是增加Fe含量和降低Pb含量的合适方法。
