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 。 Magnetized fly ash compound fertilizer is a new type of fertilizer, in order to explore its impact on cotton yield, we conducted tests in the drained soil in Yanjin County, the general amount of fly ash magnetic fertilizer on cotton is about 92 1.38kg / hm2 . The yield increase was from 15.8% to 18.4% and the yield was from 134 to 167 kg / hm2. The highest yield of fly ash magnetized fertilizer was 12 35.85kg / hm2. The yield of cotton was 1117.2 7kg / hm2. The optimum yield of fly ash magnetized fertilizer was 92 1.38kg / hm2 and the cotton yield was 10 96.3kg / hm2.
