It was conducted with Jimai 22 to study the effects of foliar fertilizer applied at the middle of wheat jointing stage and heading stage on the wheat yield and its components，the content of zinc(Zn)，iron(Fe)，and selenium(Se) and the distribution proportion of trace elements content in different organs on the basis of the application of NPK.The results showed that foliar fertilizer improved the wheat yield and its components，the effect of increasing yield was spraying Fe> spraying Se> spraying Zn.Compared with CK，the difference of spaying Fe was not significant.It increased the content of corresponding trace elements in grain，stem leaf and glume shell.The effect of Se fertilizer was the most obvious，and the Zn fertilizer was the second.The absorption of wheat grains to the 3 elements affected each other，Zn and Se，Fe and Se promoted each other，while Fe inhibit the absorption of Zn.The proportion of Zn in grain was slightly higher than that in stem and leaf，and proportion of Fe in grain was only 6.87%～8.25%，and the ratio of Se in grain was slightly lower than that in stem and leaf.It indicated that spraying 0.4% ZnSO4·7H2O 750 kg/hm2 and 0.017% Na2SeO3 750 kg/hm2 on winter wheat leaf surface at the middle of the wheat jointing stage and heading stage in Linfen basin significantly increased the content of Zn and Se in the grain to improve its quality.And spraying 03% FeSO4·7H2O 750 kg/hm2 on leaf surface improved the yield to some extent .
