摘　　要：通过对杂交油菜施用粉煤灰磁化复合肥的试验研究,初步探明了粉煤灰磁化复合肥较同等N、P、K的复混肥,未磁化粉煤灰复合肥及当地群众习惯施肥法有显著的增产效果。试验表明,粉煤灰磁化肥在油菜上一般用量为757.58 kg/hm2左右。粉煤灰磁化肥比对照增产21.9%,比当地农民习惯施肥措施增产10.5%;比等量N、P、K混合肥增产9.9%,增产180 kg/hm2。比未磁化粉煤灰复混肥增产4.5%。最高产量施用粉煤灰磁化肥为1026.9 kg/hm2,油菜产量为2084.85 kg/hm2;最佳产量施用粉煤灰磁化肥为757.58 kg/hm2,油菜产量为2041.79 kg/ hm2。The magnetized fly-ash compound fertilizer is a new type fertilizer one. Experimental study on effect of this fertilizer on hybrid oil-cabbage yield on Huanghe soils in Xinyang county was conducted. Application rate of magnetized fly-ash compound fertilizer on hybrid oil-cabbage was 757.58 kg/hm2 hybrid oil-cabbage yield was 2041.79 kg/hm2 by applying magnetized fly-ash compound fertilizer. It was 360 kg/hm2 or 21.9% higher than the CK抯; 190.0 kg/hm2 or 10.5% higher than farmer抯 traditional fertilization practices? and 180 kg/hm2 or 9.9% higher than the same amount of N, P, K compound fertilizer抯; and 86.7 kg/hm2 or 4.5% higher than the non-magnetized fly-ash compound fertilizer抯. The hybrid oil-cabbage maximum yield came to be 2084.85 kg/hm2 with applying 1026.9 kg/hm2 of magnetized fly-ash compound fertilizer. The optimum amount of application was 757.58 kg/hm2 of magnetized fly-ash compound fertilizer which derived 2041.79 kg/hm2 hybrid oil-cabbage yield. The result shown that the magnetized fly-ash compound fertilizer have notable effect on improvement of hybrid oil-cabbage economic properties.
