The present invention relates to a rice seedling substrate and a preparation method thereof, which is of the technical field of rice planting. The rice seedling substrate according to the invention was prepared from the raw materials includes the following by volume: 40-60% of dredging sediment, 30-50% of vegetable straw, and 10-30% of hickory shell. The rice seedling substrate according to the invention can not only turn waste into treasure to improve the recycling rate of sediment and agricultural and forestry waste resources, but also save the limited cultivated soils, reduce the production cost of rice seedling substrate, and promote the healthy and sustainable development of rice planting. Therefore, The inventive substrate has significant benefits in terms of economics, sociology and ecology.
