dc.description.abstractThe content and distribution characteristics of REE in spinach and soil under using REE and acid rain stress were studied by pot experiments. The results show that the content of REE is 0.527~0.696 (μg·g - 1) in the above2ground portion of spinach , 21668~31003 (μg·g - 1) in the under2ground portion of spinach and 229109~ 250130 (μg·g - 1) in the soil . With the acidity of acid rain increasing , the leaching of REE in plants and soil is strengthened and the amount of REE reduces with decreasing of pH value . After REE are used , though plants show the selective absorption to Ce group elements (especially spraying on leaves) , regardless under acid rain stress or using REE or not , the distribution model of REE in the above2ground and under2ground portion of plants is basical2 ly the same with the control . Plants also follow the Oddo2Harkins rule of the REE of distribution abundance , light rare earth elements is enriched , the minus of Eu is abnormal and admeasure of Ce is a rich model . The results show that REE in plants mainly come from soil and are affected by it .zh_CN
