Preparation method and application of biological seedling raising substrate of chaetomium globosum

The invention provides a preparation method and application of a biological seedling raising substrate of chaetomium globosum, and belongs to the technical field of agricultural microorganisms. The method comprises the steps that after preliminary fermentation is performed on agricultural waste, the agricultural waste is inoculated with chaetomium globosum ND35 sexual conidial powder to perform secondary fermentation, so that a functional flora taking chaetomium globosum as the main microorganisms in the substrate, and the biological seedling raising substrate of chaetomium globosum is obtained. The agricultural waste comprises, but is not limited to, bark, wood chips, straw and the like. The preparation method and application of the biological seedling raising substrate of chaetomium globosum have the advantages of being simple, being capable of being directly applied to the seedling raising stages of tomatoes, cucumbers and other plants, planting chaetomium globosum ND35 bacterial strains into the plants mo
