摘要：

为了探究微生物EM菌肥对粮食作物——玉米的肥料效应和增产效果，通过选用地力旺微生物EM菌肥在‘晋单63号’玉米拔节期、大喇叭口期喷施，研究其对玉米产量的影响。结果表明，在常规田间管理情况下，能使植株增高、果穗增长、凸尖变短、穗行数、行粒数和粒重增加，喷施一次增产幅度为19.47%，喷施二次比喷施一次增产效果不明显。因此建议在玉米大喇叭口期600倍液喷施一次地力旺EM菌肥。

Abstract:

In order to research how the EM microbial fertilizer effect the food crops-corn and the effects of increasing, through spraying the EM microbial fertilizer in the ‘Jindan No. 63’ corn at jointing stage and huge bellbottom period, study the influence on corn yield. Results showed that, in conventional field management cases, EM microbial fertilizer can increase the plant height and corn ear, decrease corn bald, ear row number, increase grain number per row and hundred grain weight. Spraying only once can increase yields by 19.47%, and had no significant difference to the yields of spraying twice. Therefore suggest that spraying 600 times liquid EM microbial fertilizer at corn huge bellbottom period.
