摘要
本文对春小麦喷施稀土十年定位试验的小麦籽粒、土壤中的稀土和放射性含量进行了分析，证明长期使用稀土后土壤，小麦籽粒中的稀土和放射性含量与对照样相比没有明显的区别。说明稀工农用不仅效益显著，而且是安全的。
o evaluate the applicability of rare earth(RE) fertilizer,RE residue in the soil and in spring wheat grown in the field that has beensprayed with RE fertilizer for ten years were de-termined.The methds used for the determina-don of RE are national standard methods ormethods proved to be reliable.The resultsshowed that after a long duration of sprayingRE fertilizer no significant differences of REresidue and α,β-radioactivity were found be-tween the wheat,the soil and their respectivecontrols.It indicates that the application of REfertilizer in agriculture is not only beneficial butalso safe.
