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.
