Abstract:Different amount of K was supplemented to the soil of K deficient area of Huai Bei.Theresults showed that the distribution of Zn in plant is leaf>seed>roof>stem,while that of Feand Mn, Cu were root>leaf>stem>seed and root>leaf>seed>stem , respectively. There aresignificabbbnt curilineal correltionships between supplying K and Zn in each organ) Fe ,Mn (inroot and leaf),but no significant correlationship between supplying K and Cu.Whcn 14Kg/muK was supplied, the concentration as well as accumulation of zn,Mn,Fe ,and Cu in the plantwere the highest. At the period between the reviving stage and sprouting stage ,wheat plantconsames half of its absorbable total amount for Zn,Mn,Fe and Cu.
Keywords:K supplement  Wheat  Trace element
