硅肥在黄河冲积土上的水稻肥效试验研究

A Study on the Effect of Silicon Fertilizer on the Rice Planted in the Alluvial Soil along the Yellow River

试验研究结果表明：无论以炼铁水淬渣还是以赤泥为基料生产的硅肥，在河南省黄河冲积平原水稻上施用均获得１５％以上的增产效果。

The result of the study shows: silicon fertilizer make of both wasfe residue of iron-smelting and red sludge make rice increase production by 15% in alluvial plain along the Yellow River, especially the silicon fertilizer from red sludge is better.
