文章摘要：對飼用玉米進行隨機區(qū)組試驗,測定了生物菌肥對玉米生長指標(biāo)（株高、干鮮比和地上生物量）、土壤有效養(yǎng)分（有效氮、有效磷和有效鉀）以及土壤微生物（細菌、真菌和放線菌）的影響。結(jié)果表明,施用生物菌肥對玉米生長有著促進作用,玉米株高和地上植物量較對照分別提高6.3%和10.1%,且與對照差異顯著（P〈0.05）;土壤有效氮、有效磷和有效鉀顯著增加（P〈0.05）,分別較對照增加7.7%,27.9%和7.5%,其中,有效磷增加明顯;土壤細菌和放線菌數(shù)量顯著增加（P〈0.05）,分別較對照增加322.0%和101.6%,而真菌的數(shù)量顯著低于對照（P〈0.05）,與對照相比,施用生物菌肥后,土壤真菌數(shù)量減少了67.9%。

Abstr：By randomized block design of experiment tested on the forage maize,the paper determined the biofertilizer＇s effects on the growth index （plant height,dry-fresh ratio and aboveground biomass）,available soil nutrention （available nitrogen,available phosphorus and available potassium）and soil microorganism（bacteria, fungi and actinomycetes）.The results showed that using the biofertilizer have promoted forage maize＇s growth, which increased the plant height （6.3%）and aboveground biomass （10.1%）compared with the contorl （P 〈0.05）.There were a significant difference （P 〈0.05）on the available nitrogen,available phosphorus and availa-ble potassium in the soil,which increased,7.7%,27.9% and 7.5% respectively compared with the control.A-mong them,the increase of available phosphorus was obvious.The edaphic bacteria and actinomycetes observ-ably increased compared to the control （P 〈0.05）,which respectively improved 322.0% and 101.6%.But,the quantity of fungi was lower than that of the contrast （P 〈0.05）,which reduced about 67.9% after using the biofertilizer.
