稀土元素在灵芝生产上的应用研究

本文探讨了稀土元素对灵芝菌丝体生长发育的影响及其增产效应。结果表明适宜浓度的稀土元素对灵芝菌丝体及子实体的生长发育有明显的促进作用。这种促进作用与稀土离子的存在形式有关。与无机离子相比，配位体态的稀土元素，在较低浓度的条件下即可获得较高而又稳定的增产效益。

APPLICATION OF RARE-EARTH ELEMENTS TO GANODERMA LUCIDUM PROPRODUCTION

In this paper, the affact of rare-earth elements on ganoderma lucidum has been studied. The results show that the growth of the hypha and the yield of the mushroom are promoted and improved greatly by adding rare-earth elements into the culture medium, and the promotion is relative to the being forms of the rare-earth element. Comparing with the inorganic substance, we can obtain higher and stable yeild by adding moderate concentration of organic forms.
