摘　　要：以玉米品种农大108为试验材料,用SPAD-502仪分别测定了不同浓度EM稀释液浸种处理后的叶色值。试验结果表明:利用不同浓度EM(有效微生物群)稀释液浸种及在玉米拔节期叶面喷施并灌根,可显著提高玉米叶片的叶绿素含量。并遴选出玉米施用EM的最佳浓度为500倍稀释液。EM （Effective Microorganism） is a kind of organic compound manure,and has been applied in crop production in more than seventy countries around the world. SPADRs（Soil and Plant Analyzer Drvelopment Readings ） were tested and analyzed for different EM concentration treatments on corn growth, the results are as follows： All three concentrations increased plant chlorophyl content after EM seed treatment, leaf spraying and root watering, although there was obvious effect difference among three treatments ,and the concentration of 500 x was screened as the optimal one in this study.
