Abstract: Effect of Zinc, Selenium and ammonium hydrogen phosphate seed fertilizer on the quality of the crude protein and mineral of the wheat bran were studied with Yong Lang No.4. The results were as follows：Applying ammonium hydrogen phosphate seed fertilizer could increase significantly the quality of Mn and Se of wheat bran; Spraying Zinc could increase significantly the quality of Zn and low differently the quality of P,Fe ,Cu of wheat bran;Spraying Selenium could increase significantly the quality of Ca,Mn,Se and low differently P,Fe,Cu,Zn of wheat bran;Spraying Zinc and Selenium at the Same Time could increase significantly the quality of Zn ,Se and low differently Crude protein ,Ca ,Fe ,P of wheat bran.
