Seedling cultivation matrix for promoting flowering of dwarfed Chinese roses

The invention provides a seedling cultivation matrix for promoting the flowering of dwarfed Chinese roses, and belongs to the technical field of garden plant cultivation. The matrix is prepared by a rural domestic waste forced ventilation composting product, vermiculite and earthworm manure according to the volume ratio, wherein the volume ratio occupied by the rural domestic waste forced ventilation composting product is 49.5-50.5%, the volume ratio occupied by the vermiculite is 19.5-20.5%, and the volume ratio occupied by the earthworm manure is 29.5-30.5%. The seedling cultivation matrix is applied to improving the cultivation of the dwarfed Chinese roses. The mass percentage of organic matters in the earthworm manure is 49%, and the mass percentage of the total nutrients including nitrogen, phosphorus pentaoxide and potassium oxide is 8.0%. The earthworm manure and the vermiculite are added to the rural domestic waste forced ventilation composting product to obtain the low-cost dwarfed Chinese rose seedl
