摘　　要：为了揭示氯化镧对镉胁迫下水稻地上部吸收矿质元素影响的程度,以8种籼稻品系为研究对象,研究了添加氯化镧后镉胁迫下水稻地上部Ca、Fe、Mg、Zn、Mn、K、Na等矿质元素含量的变化.研究结果表明,相对于未经LaCl_3处理过水稻品系,经LaCl_3处理过的水稻吸收矿质元素含量主要表现为减少,其中,Mn元素含量减少最明显,Fe与Zn元素含量增加最明显;此外,不同品系间吸收主要矿质元素的含量变化也存在一定差异,其中,TJS-3、TJS-7品系对矿质元素吸收量减少最明显,TJS-2品系对矿质元素吸收量增加最明显.The effects of lanthanum chloride on absorption of major mineral elements （calcium, iron, magnesium, zinc, manganese, potassium and sodium） above ground by different rice shoots under cadmium stress were studied. Compared with rice without LaCh treated, the content of mineral elements absorbed by rice treated with LaCh was mainly reduced. The manganese decreased most obviously, while iron and zinc element increased most obviously. In addition, there were some differences in the content of main mineral elements absorbed among different lines, among which, TJS-3, TJS-7 lines decreased the absorption of mineral elements most obviously, and the uptake of mineral elements by the TJS-2 lines was the most obvious.
