A tobacco planting soil structure belongs to the technical field of tobacco planting. The tobacco planting soil structure comprises a soil plough layer, at least one group of planting holes, ceramic particles, vinasse fertilizer and soil, wherein the planting holes are conical holes with downward tips, the planting holes are formed in the soil plough layer, the thickness of the planting holes is smaller than that of the soil plough layer, the ceramic particles, the vinasse fertilizer and the soil are mixed and filled in the planting holes, and the filling height is seven eighth of the height from the bottom to the planting holes. Soil hardening and poor ventilation of tobacco rhizosphere soil exist in the prior art. According to the tobacco planting soil structure disclosed by the utilitymodel, the soil ventilation porosity is improved, and the air permeability and the drainage property of tobacco land soil can be remarkably improved, so that the yield and the quality of tobacco leaves are remarkably improved, and the economic benefit of tobacco is increased.
