Abstract: Iron(Fe),zinc(Zn)and selenium(Se)are essential trace mineral elements in the organism and play an important role in the growth and development of plants,animals and human body. This work is to increase the contents of Fe,Zn and Se in wheat grain and further analyze the effects of iron,zinc,selenium fertilizer and their combinations on the contents of iron,zinc,selenium and other mineral elements in wheat grain,meanwhile to explore the most appropriate combination of foliar spraying. We used different concentration of Fe(ferrous sulfate),Zn(zinc sulfate)and Se(sodium selenite)fertilizers and their combinations to be sprayed to the leaves of wheat cultivar BJ0045. The results showed that spraying Fe,Zn and Se fertilizers significantly increased the contents of Fe,Zn and Se in BJ0045 grain. Fe and Zn promoted each other’s absorption. Zn enhanced the absorption of Se and Fe,whereas Se inhibited Zn absorption slightly. The mixed Fe/Zn/Se fertilizer significantly raised the content of Fe,Zn and Se in wheat grain among all combinations. we also found that the different combinations of foliar spray affected differently the absorptions of Ca,Mg,Cu,Mn,and P mineral elements in the grain.
