Application of trichoderma pseudokoningii SMF2 bacterial strains in plant growth promotion

The invention relates to the application of trichoderma pseudokoningii SMF2 bacterial strains in plant growth promotion, and belongs to the technical field of microorganism application. According to the technical scheme, plant growth is promoted according to the following the steps of firstly, preparing a trichoderma pseudokoningii SMF2 microbial agent into a solution which is 100 times the concentration of the trichoderma pseudokoningii SMF2 microbial agent and conducting seed soaking processing; secondly, conducting root dipping processing when trichoderma pseudokoningii SMF2 microbial agent seedlings are transplanted; thirdly, evenly mixing the trichoderma pseudokoningii SMF2 microbial agent with organic fertilizer or fine sandy soil according to the ratio of 1:10 and conducting basal application processing. The trichoderma pseudokoningii SMF2 microbial agent can effectively promote the germination of seeds, the growth of the seedlings and the yield and the quality of crops, and has good application potential in the agricultural production process.
