摘要
硅元素被视为第四大植物营养元素。有效硅对水稻的具有重要意义,其影响水稻的生长发育、光合作用和蒸腾作用、病害防御、金属离子毒害作用等。高炉水淬渣是良好的硅肥原料,需要经过活化后可以作为硅肥使用。本文介绍了通过熔态调质对高炉渣中有效硅进行活化的原理及方法,并且通过SEM-EDS、XRD等手段检测分析了活化后物质的矿物结构与有效硅含量的关系。获得了有效硅含量大于20%,即满足硅肥标准的物质。为高炉渣作为硅肥原料使用提供参考方法。
Silicon is considered as the fourth most nutritious element of plants. Eff ective silicon is great importance to rice, which affects the growth and development, photosynthesis, transpiration, disease prevention and metal ion poisoning of rice. Water-quenched blast furnace slag is a good raw material for silicon fertilizer, which can be used as silicon fertilizer after activation. That the activated principles and methods of available silicon in blast furnace slag by molten adjusted were introduced in this paper, and the relationship between the available silicon contents and the mineral structure after activation were analyzed using SEM - EDS and XRD. The available silicon content can be more than 20%, that is, it can meet the standard of silicon fertilizer. It provides a reference method for using blast furnace slag as silicon fertilizer raw material.
