Abstract

The study on the effect of fertilization on the quality of maize grain was conducted based on continue application of fertilizer for 26 and 36 years in gleyic cambisols. The amounts of protein, starch, fat and amino acid were determined and the amino acid was analyzed by cluster analysis. The results showed: Long-term fertilization 26 years showed that N₂K and N₂P processing protein content as high as 9.01, 9.01%, lowest comparing CK treatment is 5.52%; all fertilizer treatments reduced the summer maize starch content, including N₂PK deal with relatively high starch content is 57.55%; N₂K processing crude fat content as high as 5.95%; N₂P processing total amino acids and essential amino acid content is the highest, 8.13 and 3.22%, respectively. Long-term fertilization 36 years (2013) summer maize grain each nutrition indicators in line with 26 years change rule.
