摘　　要：以K2O-RO-SiO2为基础玻璃组分,矿渣为主要原料,添加作物所需微量营养元素,用高温熔制或烧结制取玻璃肥料。经过XRD分析和原子吸收检测,并对肥料做淋溶实验。结果表明用矿渣制备的玻璃肥料具有良好的缓释性能,适宜于作物栽培。The glass fertilizer is a kind of slow-release fertilizer. Compared to the fast effective fertilizer it has more advantage and has a good future in the agriculture field. Today the study of glass fertilizer is only focused on phosphate glass fertilizer and borate glass fertilizer field. In this thesis the author used the K2O-RO-SiO2 glass as the basic glass, added some other elements, which plants require, then fusedin high or low temperature, and finally got some kinds of fertilizer. From the result of the XRD and ICP we can conclude that the glass which fused by this method is a good slow release glass fertilizer and could be used in agriculture field.
