In order to study the effect of spraying different foliar barrier on the control of cadmium in spring wheat in northernfields， ‘Yongliang 4’was used as thematerial，and four different mineral elemental foliar barrier agents were sprayed on wheat at the tillering stage and thespikestage，namely，mixedtype(MAC)，manganese -zinc elementaltype(MZ)， sulphur elementaltype(S)，and silicon elementaltype(Si)，and the foliar barrier agents were applied at the tilleringstage and spikestage，at the sametime，water spraying was set asthecontrol，and the blocking and controlling effects of different foliar barrier agents on cadmium in wheat were analyzed by determining the cadmium content in various organs ofwheat.The results showedthat:(1)Compared with the watercontrol，four different mineral element type of foliar barrier agents effectively reduced the cadmium contentin wheatgrains，of which，MZ，S treatment made the cadmium reduced in the grainssignificantly，and the cadmium reduction ability of the four foliar barrier agents was ranked asMZ>S>Si>MAC， which reduced the cadmium content in thegrains by47.7%，40.1%，33.3% and26.5%，respectively.(2)The Cd enrichment coefficients of various organs of wheat were ranked asroot>stem>leaf>glume>seed，and the foliar spraying of all four mineral-element-based barrier agents inhibited the enrichment ability of wheatseed，while MAC and MZ increased the enrichment ability of wheat rootand inhibited the accumulation of Cd inleaves.(3)MAC and MZ barrier agents inhibited cadmium transfer from root tostem，while S and Si treatments mainly inhibited cadmium transport from leaf toseed.Therefore，in termsof blocking Cd contamination in wheat by foliar spraying of barrieragents，spraying of MZ and S types of foliar barrier agents could be selected.
