【摘要】 本文报导了从子实体组织和孢子分离得到形成蘑菇圈的香白蘑[Lepista caespitosa(Bres)sing]菌种。它与能形成蘑菇圈的口蘑(Tricholoma gainbosum)在某些生理生化特性上具有明显差别。通过埋片法发现,蘑菇圈的地下生长着浓密的菌丝体,而且蘑菇圈是随着菌丝体的延伸而移动的。蘑菇圈主要是由于菌丝体的代谢产物而不是由于菌丝体分解生成的氮素所引起的。几年来在蘑菇圈上种植的作物(大豆、小麦、谷子、高粱、玉米)均获得很高的产量。更多还原

【Abstract】 Lepista caespitosa, which causes the formation of Fairy Ring, has been isolated from the tissue of fruiting body and from sporidium. It is different from Tricholoma gambosum in some physiological and biochemical characters. By using the method of sheets glass buried in soil, thick mycelium was found under the Fairy Ring, and the Fairy Ring moves along with the development and stretch of the mycelium. It is clearly shown that Fairy Ring is caused mainly by the metabolites of the mycelium rather than nitrogen source from the decomposition of the mycelium.The high yields of the crops (soybean, wheat, corn, Chinese sorghum and millet) on the Fairy Ring were obtained for several years.更多还原
