The invention relates to a simple and labor saving fertilization method for summer maize under a wheat and maize rotation mode. The method comprises the steps: harvesting wheat, then, smashing strawsto be completely returned to the field, next, sowing maize, and applying elementary substance fertilizers including a nitrogen fertilizer, a phosphorus fertilizer and a elementary fertilizer at one time during sowing maize, wherein topdressing is not needed in the whole growth period. The nitrogen fertilizer is a mixture of coated urea and ordinary urea, wherein the mass ratio of the coated urea is 60-80%, and the mass ratio of the ordinary urea is 20-40%. The fertilizers applied in the method are the elementary substance fertilizers by which the demands for nutrients in the whole growth period of maize can be met and topdressing is not needed in the whole process, so that the labor cost is reduced, the utilization ratio of the nitrogen fertilizer is greatly increased, the leaching loss ofthe nutrients along with rainwater is reduced, the nutrient supply during stem elongation and booting of maize is guaranteed, the yield of maize is greatly increased, stable production and yield increment is favorably realized, and meanwhile, the investment cost is greatly reduced.
