The invention provides a planting device for wilderness no-irrigation ecological restoration. The planting device comprises a particle layer and a partition plate, a soil layer is arranged at the bottom of the particle layer, and the partition plate is arranged at the bottom of the soil layer. Salinity is blocked by the partition plate, a water source is conserved, the partition plate contains mineral substances, the device solves the problem that an existing water-retaining agent is easily decomposed, the partition plate can penetrates water at a certain speed according to the material and the shape of the partition plate, a certain quantity of water can be stored, respiration of roots of plants is ensured, the roots cannot be rotted, the soil on the partition plate has the functions of retaining water and supporting fertilizers, infiltration loss of nutrients is reduced, the soil can return moisture to form 'gold covering soil', soil water is normally retained for 1-2 days and even retained for 7-8 days, a multi-stage soil water-retaining structure is reversely conical, water-retaining effects are better, a water pipe conveys water to a bottom planer, the water is induced to movefrom top to bottom, and the planting device has wide applicability in the field of desertification restoration.
