【摘要】 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更多还原

【Abstract】 The food quality in the areas of different contents of rareearth elements was studied. The results shows that rareearth elements can improve the accumlation of protein and P2O5 in food and oil crops, and increase the absorbation of more elements in acidsoil. The data indicates that tlere is linear relationship between the contents of nutrient elements and the acculmation of rareearth elements in the acid soil contenting much more rareearth.更多还原
