臭氧水对双孢蘑菇菌丝生长的影响

Effect of Ozone Water on Mycelia Growth of Agaricus bisporus

[目的]探究双孢蘑菇生长发育过程中不同臭氧添加量对双孢蘑菇菌丝生长的影响。[方法]以双孢蘑菇菌种W192为研究对象,比较其在不同浓度臭氧水含量(臭氧水占比0~100%)的栽培基质中菌丝的生长情况和杂菌发生率。[结果]臭氧水对双孢蘑菇菌丝的生长有显著的促进作用:臭氧水含量较高的栽培基质中的双孢蘑菇菌丝更为浓密,生长速度更快,杂菌发生率更低;臭氧水占比为100%时,菌丝生长速度为5.65 mm/d,满瓶时间为20 d,其杂菌发生率最低,为13.3%。[结论]以臭氧水代替普通自来水制作双孢蘑菇栽培基质具有可行性,实用性强,值得推广。

[Objective]The aim was to investigate the effects of different ozone levels on mycelial growth of Agaricus bisporus during its growth and development.[Method]Taking A.bisporus strain W192 as the research object,the mycelia growth and the incidence of miscellaneous bacteria were compared in the culture medium with different ozone water content(0-100%ozone water proportion).[Result]Ozone water can significantly promote the growth of mycelia of A.bisporus:the mycelia of A.bisporus in the cultivation medium with higher ozone water content is more dense,the growth rate is faster,and the incidence of hybrid bacteria is lower.When the proportion of ozone water was 100%,the growth rate of mycelium was 5.65 mm/d,and the full bottle time was 20 days,and the incidence of heterobacteria was the lowest(13.3%).[Conclusion]The method of using ozone water instead of ordinary tap water to make the cultivation substrate of A.bisporus is feasible,practical and worth popularizing.
