| 摘 要： | 研究了不同氮源对犬球盖菇菌丝生长的影响，结果表明大球盖菇菌丝生长最适氮源是尿素，其适宜浓度是0．026％；蛋白胨次之，其适宜浓度是0．1％；硫酸铵最差。大球盖菇菌丝生长对氮源浓度极敏感，低浓度氮促进菌丝生长，高浓度氮显著抑制菌丝生长。 |

| Abstract: | Effects of different nitrogen sources on mycelial growth of Stropharia rugoso-annulata were studied. The results showed that optimum nitrogen source was urea, and its suitable concentration was 0.026%, then was peptone, （NH4）2SO4 （0.1%） was the worst. Mycelial growth of Stropharia rugoso-annulata was extremely sensitive to concentration of nitrogen sources, and the lower concentration promoted the growth, otherwise the growth was restrained outstanding. |
