The absorption and content distribution of 5REs (La,Ce,Nd,Y and Gd) in 3species of crops (corn,paddy and soybean )have been studied. The results show that there exists the positive relationship between capability of rare earth elements being absorbed by crops and available rare earth elements in soil. Generally,content distribution of rare earth elements in crops are root >leaf >stem >fruit. Distribution of unitary rare earth elements in root is La>Ce>Nd>Y>Gd,and in leaf ,stem and fruit is Ce>La>Nd>Y>Gd. It is proved that light rare earth elements absorbed are easier than heavy rare earth elements. In addition ,capability of rare earth elements absorbed in crops growing is seedling >ramification >maturity . In a word,the data of pot experiment show that most of bioaccumulation in root . Thus, it is helpful to agricultural application of rare earths.
