| Abstract: | Based on field experiment, this paper studied and compared the growth characteristics and yield of corn between formula fertilization and routine fertilization. The results showed that the formula fertilization increased the corn yields as well as its economic returns when the feasible rate of NPK fertilizers in formula fertilization were N∶P2O5∶K2O=1∶0.5∶（0.4～0.5）. |
