Composite microbial composition and application thereof

The invention discloses a composite microbial composition and application thereof. The composite microbial composition provided by the invention contains three microorganisms, namely trichoderma harzianum, penicillium beijerinckii and Metarhizium pinghaense, and the characteristics of each strain are fully utilized. The composite microbial composition can be prepared into a dry powder type seed coating agent and a suspension type seed coating agent, the seed coating agent is simple to prepare and convenient to use, three microorganisms can be effectively colonized in seeds, and the activity and stability of each strain are maintained; and the compound can also be used with various chemical seed coating agents, has obvious effects on effectively inhibiting plant diseases (especially basal rot and northern leaf blight), inhibiting plant insect pests and promoting plant growth, and has important application prospects and economic values. 本发明公开了一种复合型微生物组合物及其应用。本发明提供的复合型微生物组合物含有哈茨木霉、拜赖青霉和平沙绿僵菌(Metarhizium pingshae
