在含磁性物质（Fe、Co、Ni）的介质中，加入适量的化肥和其它添加物质，经一定磁场强度磁化后制成的具有剩磁和矫顽力的新型肥料，定名为磁化肥料，现已获得国家发明专利。目前提供大量磁性物质的主要载体是火力发电厂排放的粉煤灰。粉煤灰和磁性粉煤灰对主要农作物的增产效果?
In the magnetic material (Fe, Co, Ni) medium, adding appropriate amount of fertilizers and other additives, after a certain magnetic field strength magnetization made of remanence and coercivity of the new fertilizer, known as the magnetized fertilizer, now Has obtained national invention patents. The main carrier currently providing a large amount of magnetic material is fly ash discharged from thermal power plants. Fly ash and magnetic fly ash on the main crops yield effect?
