The invention provides a method for compacting yellow clay soil in an open-air dump site, which comprises uniformly mixing sandy soil and yellow clay in a mass ratio of 1:1 to 3:1 to obtain a soil matrix; planting locally suitable plants in the soil matrix Plants; inoculate arbuscular mycorrhizal fungal propagules in the soil matrix of the rhizosphere of each plant; cultivate the plants so that the fungus and the plant are symbiotic. By matching sandy soil and yellow clay in a certain proportion, the invention has the advantages of convenient soil borrowing, wide sources, low cost, and is more suitable for rapid structural improvement and inoculation of arbuscular mycorrhizal fungi for compacting yellow clay soil in local open dumps. It has many advantages such as improving the survival rate and biomass of vegetation, improving soil and not producing negative effects. |
