稀土元素是锢系元素以及钪、钇等１７种元素的总称。稀土能强化硝酸还原酶的活性，增强细胞对培养料内无机氮的吸收、转化和利用，促进菌丝生长。为了探索稀土在金针菇上的应用，我们在稀土对金针菇产量及蛋白质含量的影响方面进行了初步探索。１ 材料和方法１．１ 供试材科① Rare earth element is a total of 17 elements such as scandium and yttrium. Rare earth can enhance the activity of nitrate reductase, enhance the absorption of inorganic nitrogen in the culture medium, transformation and utilization, and promote mycelial growth. In order to explore the application of rare earth mushrooms, we conducted a preliminary exploration on the effects of rare earth on the yield and protein content of mushroom. 1 Materials and methods 1.1 for the test materials ①
