| Abstract: | Physically based on the green house and yield experiments,and advanced INAA(Instrument Neutron Activity Analysis) technique,the absorption and distribution characteristics of REE(Rare Earth Elements) in main crops of loess plateau are determined and analysed.All data determined provide basic material for the application of REE to agriculture.The important information that REE influence on crops is expected to obtain from the reseach results.These achievements provide scientific evidences for wide application of REE in loess plateau region. |
