The invention discloses a watering method for corn seedling protection and yield stabilization.The watering method includes the steps of watering in a seeding period, watering in an emergence period, watering from a large horn mouth period to a spinning period, watering in a filling stage and watering in a mature period.Soil is disinfected at high temperature, the cold resistance and drought resistance of corn seedlings are enhanced, leaf fertilization and two times of drop irrigation are conducted from the large horn mouth period to the spinning period, the problems that in the corn growth and development process, due to water shortage, filaments and anther develop poorly, spinning and pollination are blocked, premature senility of leaves is generated, photosynthesis and nutrient transport capacity are reduced, abortive grains are increased, and the grain weight is reduced are solved, cold water irrigation is adopted when high-temperature drought occurs in the spinning period, and corn plants are rapidly coo
