Abstract: In the production of summer maize, the problems of excessive fertilizer input and low fertilizer utilization rate are common, resulting in the waste of resources and environmental pollution. In order to explore the optimal fertilization mode of summer maize, a field experiment with eight treatments was designed in which sowing and fertilization were carried out by different machines. The effects of the two fertilization methods, i.e., hole fertilization and strip fertilization; two fertilization positions, i.e., side-position fertilization and positive-position fertilization; and two fertilization depths, i.e., 10 cm and 15 cm, on the summer maize yield, plant nitrogen, phosphorus, and potassium nutrient accumulation, and aboveground biomass were studied. The results show that different fertilization modes had significant effects on summer maize yield, nitrogen, phosphorus, and potassium nutrient accumulation, and aboveground biomass. In general, when the strip fertilization method was used, 15 cm deep positive-position fertilization was superior. When the hole fertilization method was used, 15 cm deep side-position fertilization was superior.
