The invention relates to the technical field of seedling culture, in particular to a biological organic seedling culture substrate and a seedling culture method. The matrix is formed by compounding modified straw particles, peat, coco coir and a bio-organic fertilizer. Wherein the modified straw particles are obtained by sequentially carrying out alkalization, two-stage etherification and calcium chloride and chitosan oligosaccharide solution treatment on wheat straw particles with specific particle sizes. The matrix synergistically improves the water-air coordination and the root lump formability. During seedling raising, the seedlings are put into a hole tray to be sown, the temperature, humidity and moisture are controlled, and strong seedlings can be cultivated within 25-30 days. The problems that a traditional substrate is prone to hardening, the root lumps are loose, and the transplanting rejuvenation period is long are effectively solved.
