The invention relates to the technical field of agricultural production, in particular to a rice seedling raising method. The method comprises the following steps of 1, seed treatment, wherein pure and plump seeds are selected to be aired on sunny days for 2-3 days, after being aired, the seeds are soaked and disinfected, and then sterile water is used for rinsing the seeds; 2, seed soaking for accelerating germination, wherein the seeds of which moisture is drained are put into a culture dish, and a germination accelerating agent is sprayed to keep the surfaces of the seeds humid; 3, preparation of seed bed soil, wherein the seed bed soil is composed of pond slit, straw leavening, chitin, medical stone, humic acid, propiconazole, urea, nitrogenous fertilizer and potash fertilizer; 4, seedling raising, wherein the seed bed soil is loaded to a seedling raising disc, the seedling raising disc is put into a seedling raising shed, then buds are sowed in the seedling raising disc, and aftersowing, the seedling raising disc is uniformly covered with soil and thoroughly dripped by water. The rice seedling raising method has the advantages that the disease resistance and germination capability of rice seedlings are improved, and the seedlings are high in survival rate.
