| 摘 要： | 采用多因素随机区组试验设计在甘肃省漳县盐井镇研究了"飞天"马铃薯专用肥两种不同配方和长效复合添加剂NAM和PAL用量对马铃薯产量和经济效益的影响。结果表明:与传统施肥处理比较,各处理组合差异显著,其中"飞天"马铃薯专用肥(N-P-K:15-8-7)中加入0.6%NAM时马铃薯产量和经济效益最高,提高产量39.1%,产值提高41.2%;两种配方肥均可显著提高马铃薯产量和经济效益,且"飞天"马铃薯专用肥(N-P-K:15-8-7)比"飞天"马铃薯专用肥(N-P-K:12-8-10)提高马铃薯产量8.5%,增加产值12.4%;在两种配方肥中加入NAM和PAL均可显著提高马铃薯产量,但是随着肥料长效剂NAM和PAL含量的增加,各处理组合马铃薯产量并无显著性增加。
