The experiment was carried out to study effect of different process compound fertilizer with the samenutrient content（N-P₂O₅-K₂O: 15-15-15）on growth characters of pot-cultured corn, which provided a theoreticalbasis for the reasonable application of different technology of compound fertilizer. The results showed that in pot-cultured corn experiments of 2010~2012, corn plant height, stem diameter, SPAD values and other growth traits atjointing stage increased in the AZF process fertilizer, potassium hydrogen sulfate method fertilizer and urea-formal-dehyde craft fertilizer treatments. More nutrients were up taken and it promoted pot-cultured corn’s growth and de-velopment compared with other treatments. In the three-year pot-cultured experiment, the aboveground biomassand belowground root dry weight, root length density of the AZF process fertilizer, potassium hydrogen sulfate meth-od and urea-formaldehyde craft were larger. Developed root system would help nutrients and moisture absorption insoil, and promote plant growth and development.
