应用14 1Ce ,采用水培的方法研究冬小麦对稀土元素的吸收和分配规律及铈在水 植物界面间的传输速率 .结果表明 ,在实验期内 ,冬小麦幼苗中铈的浓度随培养时间的延长而增加 ,随培养液中铈浓度的提高而增加 ;铈在冬小麦各器官中的浓度 ,根部的远大于在茎叶中的 ;吸收速率是较高浓度处理的要高于较低浓度处理的 ,并且在不同培养期中的吸收速率是不相同的 .对冬小麦的吸收速率随时间的变化规律进行了拟合 ,给出了定量描述公式 .
14Ce was used to study the absorption and distribution of rare earth elements in winter wheat and the transmission rate of cerium between the water and plant plants by hydroponic culture.The results showed that the concentration of cerium in winter wheat seedling increased with the incubation time Increase with the increase of the concentration of cerium in the culture medium; the concentration of cerium in all organs of winter wheat is much larger than that in stems and leaves; the treatment with higher absorption rate is higher than the lower concentration, and The absorption rate of winter wheat in different culture periods was different, and the law of absorption rate of winter wheat with time was fitted and the quantitative description formula was given.
