通过对稀土不同含量区粮油作物品质的研究，得知稀土元素能促进粮油作物籽粒中蛋白质和Ｐ２Ｏ５的积累，且具有提高酸性土壤作物吸收多种元素的能力。从试验数据中看出，富含稀土的酸性土壤上生长的粮食中营养元素的含量与稀土累积呈正相关 Based on the studies on crop quality of grain and oil with different contents of rare earths, it is found that rare earth elements can promote the accumulation of protein and P2O5 in grains of grain and oilseeds, and improve the ability of acid soil crops to absorb many kinds of elements. From the experimental data, it can be seen that the content of nutrients in grain grown on rare earth-rich acidic soil is positively correlated with the accumulation of rare earth
