Abstract: Nutrition characters of high rod。middle rod and low rod spring wheat ha-ve been studied through out two years with field tests and chemical analysis in the laboratory.This paper illustrates mainly following aspects:General charac-ter and difference of concentration of N,P,K in various spring wheats;credible range of consume coefficient and production efficiency of above three main ele-ments;general character and special character of absorption curves among spe-cies:distribution and movement of three main elements in wheat plant; of three main elements in spike etc.It provides a basis for technique of casting fertilizer on different spring wheats which are different in enduring fertilizer,
