The invention belongs to the field of microbial agents, and particularly relates to a microbial preparation for improving the iron deficiency stress resistance of crops and application of the microbial preparation. Compared with arbuscular mycorrhizal fungi, azospirillum brazilianum single fungicide and other mixed fungicide formed by mixed culture of azospirillum brazilianum and arbuscular mycorrhizal fungi, the microbial preparation provided by the invention has better effects of promoting crop seed germination and crop growth, and can effectively improve iron deficiency yellowing symptoms of crops. 本发明属于微生物菌剂领域，具体涉及一种提升作物对抗缺铁胁迫能力的微生物制剂及其应用，本发明请求保护的微生物制剂为丛枝菌根真菌和巴西固氮螺菌混合培养形成的复合菌剂，相对于丛枝菌根真菌、巴西固氮螺菌单一菌剂以及其它固氮螺菌与丛枝菌根真菌混合培养形成的混合菌剂，本发明提供的微生物制剂具有更优的促作物种子萌发以及促作物生长的效果，并能够有效改善作物缺铁黄化症状。
