摘要:
黄芪是我国重要的大宗药材之一,化肥、农药的过量施加严重制约着黄芪产业的可持续发展。植物根际放线菌在提高作物产量、防治病害方面具有很大的应用潜力。内蒙古达茂旗是蒙古黄芪的主产及道地产区,然而,关于该地区黄芪根际可培养放线菌的多样性及其促生作用尚不清楚。从内蒙古达茂旗采集蒙古黄芪根际土样品,分离、鉴定黄芪根际放线菌,利用盆栽试验检测根际放线菌对黄芪的促生作用,并通过检测其促生功能初步探究其促生机理。从蒙古黄芪根际共分离得到33个菌株,分属于放线菌的3个属13个种,链霉菌属(Streptomyces)为优势菌属,阿姆利则链霉菌(S.amritsarensis)、易变链霉菌(S.mutabilis)以及纺锤雷素链霉菌(S.netropsis)为优势菌种。其中,8株放线菌对黄芪幼苗具有显著促生作用,其均属于Streptomyces,且均具有溶解无机磷和有机磷的能力,部分菌株同时具有固氮和产铁载体的能力。内蒙古达茂旗蒙古黄芪根际放线菌及其促生菌的优势菌属均为Streptomyces,主要通过促进黄芪对磷的吸收利用来发挥促生作用。本研究为蒙古黄芪根际放线菌的深入研究及应用提供了理论参考。
