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。
The effects of different nitrogen sources on the mycelial growth of Rubulaceu were studied. The results showed that the optimal nitrogen source for the growth of Betula platyphylla was urea. The optimum nitrogen concentration was 0.026%. The optimum concentration of peptone was 0.1%. Ammonium sulfate is the worst. Pleurotus ostreatus growth is very sensitive to nitrogen source concentration, low concentrations of nitrogen promote mycelial growth, high concentrations of nitrogen significantly inhibited mycelial growth.
