摘要
粉煤灰的颗粒组成以微细的玻璃体为主,其颗粒组成决定了粉煤灰可用作土壤改良剂。但由于单一废弃物的营养元素常不平衡或物理性质不够理想,单独用于土壤中容易造成一些负面影响,故采用粉煤灰和有机固体废弃物配施,为植物生长提供更充分的营养物质和能量。
The particle of coal ash composition by the tiny vitreous body primarily, its parlicle composition have decide the pulverized coal ash may serve as the soil modifier. But the sole reject nutrilion Element usually not balanced or the physical property insufficiently, alone uses in the soil easy haviag some negative influences, so uses the coal ash and the organie solid reject matching use, provides the fuller nutrients and the energy for the plant growth.
