The invention provides a fungus treatment and a method for improving drought resistance of wheat at seedling stage, and relates to the technical field of fungus treatment for drought resistance. The fungal treatment and method for improving drought resistance of wheat at seedling stage include the following steps: S1. Selecting wheat plants and strains; S2. Classifying inoculated microbial flora; S3. Treating the inoculated microbial floras; S4. Mixing fungal strain suspension, and inoculating seedlings; and S5. Imaging by scanning electron microscope. By isolating the microbial flora of the taproot from Yunhan 618 wheat plant, synthesizing five microbial floras, and inoculating to Chinese spring wheat, the fungi for improving the drought resistance of wheat are obtained.
