以粉煤灰为主要载体的粉煤灰磁化复合肥(简称磁化肥 ) ,是经特殊磁化工艺 ,强化了粉煤灰中铁磁物质的磁功能 ,然后加入适量的Ｎ、Ｐ、Ｋ肥和微量元素加工而成。为了探讨磁化肥在杂交水稻上的增产效应 ,于 1998～ 1999年进行了该项试验研究。1　材料与方法供试土壤为黄褐土性潴 With fly ash as the main carrier of fly ash magnetized compound fertilizer (referred to as magnetic fertilizer), is a special magnetization process, strengthening the magnetic properties of the ferromagnetic fly ash, and then add the appropriate amount of N, P, K fertilizer and trace Elements processed. In order to investigate the yield-increasing effect of magnetic fertilizer on hybrid rice, this experimental study was conducted from 1998 to 1999. 1 materials and methods for the test soil yellowish brown soil retention
