有效微生物群在玉米生产中作用机理研究

Studies on the Action Mechanism of Effective Micro-organisms in Corn Production

有效微生物群（ＥＭ）对萌发种子中酶活性有较大影响。除ＥＭ原液外，各种浓度的ＥＭ稀释液浸种都能不同程度提高ａ－淀粉酶活性和ＣＡＴ活性。叶面喷施ＥＭ能显著提高叶片光合作用速率及干旱条件下ＳＯＤ和ＣＡＴ活性，具有促生长和抗旱作用。ＥＭ还能加速有机质分解。

Soaking with EM dilute solution could influence the activities of a-amylase and CAT in germinated seed of corn.All concentration enhanced the activities of a-amylase and CAT except original EM solution.Spraying the EM dilute solution evidently raises the photosynthetic rate under normal conditions and the activeties of SOD and CAT under drought condition.Which showed that EM has the functions of advancing growth and drought resistance.EM could promote the release of soil available nutrients and the decomposition of organic matter.
