The present invention relates to the technical field of culture medium for bulbous plants, and particularly relates to a kind of hydrophobic culture medium for bulbous plants, which comprises a base layer from bottom to top, a waterproof layer laid on the surface of the base layer, a filling layer laid on the surface of the waterproof layer, a canvas layer laid on the surface of the filling layer, and a loose matrix layer laid on the surface of the canvas layer. The longitudinal section of the culture medium is high in the middle and low on both sides. The culture medium has good water repellency and strong air permeability, and is particularly suitable for the growth of bulbous plants.
