Four groups of field experiments including REEs foliage dressing, soil dressing, triple amounts of soil dressing and control were carried out. Contents of REEs in wheat in different growing stages were measured by ICP MS. The results show that REEs amount in leaves increases significantly with foliage dressing in jointing stage, in addition to REEs accumulation with soil dressing method in jointing stage. Either using foliage dressing or soil dressing, there is no significant accumulation in mature stage. Comparison of the two methods shows that lower amount of REEs with foliage dressing can be highly absorbed in jointing stage.
