The invention provides a low-temperature-resistant seed soaking agent for rice in a bud stage as well as a preparation method and application thereof. The rice bud stage low-temperature-resistant seedsoaking agent is formed by mixing an abscisic acid solution with the mass concentration of 9-11 mg/L, a monopotassium phosphate solution with the mass concentration of 5-7 g/L and a uniconazole solution with the mass concentration of 29-31 mg/L, wherein the volume ratio of the abscisic acid solution to the monopotassium phosphate solution to the uniconazole solution is (2-4): (1-3): (0.5-1.5). The...
