本研究进行富稀土金针菇和农用硝酸稀土对小鼠生长、发育及用力的对比试验。结果表明，饲喂富稀土金针菇的小鼠，三周后体脏重及时力均显著高于无稀土的金针菇对照组（Ｅ组），且表现出一定的剂量效应。与饲喂硝酸稀土的小鼠（Ｄ组）相比，当添加的稀土量相等时，饲喂富稀土金针菇的小鼠（Ｂ组）体重和脏器重明显增加，游泳时间延长２８．６％，游泳后Ｂ组血乳酸含量的变化明显低于Ｃ、Ｄ、Ｅ组，血糖含量下降率较小。可见，将适量富稀土金针菇（其含量为８．１μｇ／ｇ）添加至饲料中，对小鼠的生长、发育、耐力提高有明显的促进作用，而直接添加稀士化合物的作用不明显，甚至表现出一定的抑制作用。
In this study, comparative experiments were conducted on the growth, development and exertion of mice enriched with Flammulina velutipes and agricultural rare earth nitrate. The results showed that body weight and timeliness of mice fed with Flammulina velutipes were significantly higher than those of the control group without Flammulina velutipes (Group E) after three weeks and showed some dose effects. Compared with the mice fed with rare earth nitrate (group D), the body weight and organ weight of the mice fed the rare earth mushroom (group B) increased significantly when the amount of added rare earths was equal, swimming time was prolonged by 28.6% After swimming, the changes of blood lactic acid in group B were significantly lower than those in groups C, D and E, and the decrease rate of blood glucose was smaller. It can be seen that the addition of appropriate amount of rare earth mushroom (its content is 8.1μg / g) to the feed can obviously promote the growth, development and endurance of the mice, while the effect of adding the rare-earth compound directly is not obvious. Showed some inhibition.
