The invention discloses a high-yield corn planting method belonging to the technical field of 
agriculture, 
forestry, 
animal husbandry, hunting, 
trapping and 
fishing, and particularly relates to a corn planting method. The invention provides the high-yield corn planting method which is high in yield and is green and 
pollution-free. The high-yield corn planting method comprises the following steps of (1) isolated planting: 
sowing by stages is carried out since sweet corn and 
waxy corn can be in out-crossing hybridization with common corn and grains of the sweet corn and the 
waxy corn can easily change into grains of the common corn; (2) seed preparation: elite 
hybrid seeds can be selected as the elite 
hybrid seeds have good yield-increasing potential and are the high-yield basis of corn; appropriate elite seeds can be selected by combining ecological types of different regions; (3) seed 
processing: appropriate seeds coated by a seed 
coating agent can be selected before seeding according to a 
local disease and pest occurrence regularity, or seed dressing 
processing can be carried out on seeds by selecting related pest killing agents, disinfecting agents, micro-element 
fertilizer and the like according to needs, so that the purposes of preventing diseases and pests and promoting the growth can be achieved; (4) land ploughing and 
land preparation: the appropriate 
tilling depth is 18 cm; the 
tilling depth can be up to 20 cm for the land which is high in 
soil fertility, thick in 
tilling layer and large in basic 
fertilizer application amount; otherwise, the tilling depth needs to be shallow; (5) seeding depth: generally, the appropriate seeding depth is 4 to 6 cm; but generally, the seeding depth is required 
not to exceed 8 cm. Attention, a great number of ineffective tillers can be generated during a 
seedling stage if the soil which is better in 
soil moisture content and better in 
fertility is subjected to too-shallow seeding.
