摘要
研究了不同氮源对大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。
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.
