摘　　要：粉煤灰磁化复合肥是一种新型肥料 ,为探讨其对棉花产量的影响 ,我们在延津县潮土上进行了试验 ,粉煤灰磁化肥在棉花上一般用量为 92 1.38kg/hm2 左右。比等量N、P、K混合肥增产 15 .8%～ 18.4% ,增产134～ 16 7kg/hm2 ,最高产量施用粉煤灰磁化肥为 12 35 .85kg/hm2 。棉花产量为 1117.2 7kg/hm2 ;最佳产量施用粉煤灰磁化肥为 92 1.38kg/hm2 ,棉花产量为 10 96 .3kg/hm2 。The magnetized fly-ash compound fertilizer is a new type one, to research it's effect on cotton output, we had an experiment on Chao soils in Yanjin county. Supply of magnetized fly-ash compound fertilizer was 921.38Kg/hm\-2 on cotton. The cotton yield was 984～1074kg/hm\+2 with supply of magnetized fly-ash compound fertilizer, 134～167 kg or 15.8～18.4% higher than the same NPK compound fertilizer's; The cotton maximum yield will be 1117.27kg/hm\+2 with 1235.85kg/hm\+2 supply of magnetized fly-ash compound fertilizer. The cotton optimized yield will be 1096.3kg/hm\+2 with 921.38kg/hm\+2 supply of magnetized fly-ash compound fertilizer.
