应用~(60)Co—γ射线0.6—1.8 Mrad辐照香菇木屑培养料(常规配方),进行辐射灭菌试验。在1.0—1.8 Mrad范围内,不仅能杀灭影响香菇菌丝生长的常见杂菌,达到辐射灭菌的目的,而且还能促进香菇菌丝生长,提高香菇产量。试验表明,其消毒灭菌的最佳辐射剂量为1.2 Mrad。用该剂量辐照香菇木屑培养料,菌丝日平均增长量、鲜菇产量与高压灭菌组比较,均达到显著和极显著水平。 Radiation sterilization experiments were carried out using ~ (60) Co-γ-ray irradiation of 0.6-1.8 Mrad for mushrooms sawdust culture medium (conventional formula). In the range of 1.0-1.8 Mrad, it not only can kill the common bacteria that affect the growth of mushroom mycelia, but also can promote the sterilization of the mushrooms and promote the growth of the mushrooms. Tests show that the best radiation dose for sterilization is 1.2 Mrad. With this dose irradiation vanilla wood sawdust culture material, the average daily growth of mycelium, fresh mushroom production compared with the autoclaved group, reached significant and extremely significant levels.
