摘　　要：在黄褐土上分别进行了添加 L a、Ce和 Nd(REO添加量为 0、30 0、6 0 0、12 0 0、180 0 mg/ kg)的试验。结果表明 :稀土添加量与土壤可溶态稀土含量的变化、土壤可溶态稀土含量与油菜体内的稀土含量、油菜体内的稀土含量与油菜的生长量之间均呈明显的相关性。 L a、Ce和La,Ce and Nd(0,300,600,1200,1800REOmg/kg)were added in yellow cinnamon soil respectively to test the effect of REO on the growth of rape.The relationship between added REO and soluble REO,the relationship between soluble REO and REO in rape,and the relationship between REO in rape and growth of rape were clearly correlated.Ce and Nd in certain concentration had clearly effect on the growth of rape.Agriculturally the increasing effect of REO for rape was mainly from Ce.
