有效微生物群在秸秆有机肥上的应用研究

Study on EM Application in Stalk Organic Manure

对EM有机肥的增产机理研究结果表明 :施用EM有机肥提高了玉米子粒的产量 ,两年试验平均比对照高 9 2 0 % ;EM有机肥与普通有机肥相比 ,玉米植株叶片光合作用速率提高 ,叶绿素含量增加 ,氮代谢能力增强 ,硝酸还原酶活性和可溶性蛋白含量提高 ;EM有机肥处理明显提高了孕穗期玉米植株的耐旱耐涝能力。收获期的田间调查结果表明 :EM有机肥处理可明显减少田间植株的倒伏率 。

The planting test showed that EM organic manure raised maize economical yield,the average increase was 9 20% than that control in 2 year test.EM organic manure enhanced leaf photosynthetic rate and chlorophyll contents,improved N metabolism of maize leaves.Relative to the control,EM organic manure also strengthened the water resistance of maize plants in booting.Field investigation in harvest showed that EM organic manure could obviously decrease stalk lodging rate,stem rot rate and head smut rate.
