应用臭氧·液体菌种生产无公害金针菇技术研究

[目的]为了改变金针菇生产周期长、常规消毒药剂残留量大、对人体的刺激严重等缺点。[方法]试验设置臭氧消毒+液体菌种、甲醛消毒+液体菌种、臭氧消毒+固体菌种、甲醛消毒+固体菌种4个组合处理,以甲醛消毒+固体菌种为对照研究比较了臭氧和液体菌种的应用技术。[结果]臭氧+液体菌种组合比对照菌丝长满培养袋时间短10 d左右,产量和产品质量明显提高,污染率下降。[结论]液体菌种和臭氧消毒在金针菇生产上是值得推广的技术。

Study on Pollution-free Production Technology of Flammulina velutipes by Applying Ozone and Liquid Strain

[Objective] The study was conducted to change some shortcomings of Flammulina velutipes,such as long production cycle,high residual quantity of conventional disinfectants,serious stimulation and harm to human body,and so on.[Method] The application technology of ozone and liquid strain were studied and compared with 4 combination treatments of ozone disinfection liquid strain,formaldehyde disinfection liquid strain,ozone disinfection solid strain and formaldehyde disinfection solid strain(CK).[Result] The time of hypha covergrowing in culture bag in the combination treatment of ozone and liquid strain was about 10 days shorter than CK and the yield and quality of products were significantly higher and the contamination rate was lower than CK.[Conclusion]The combination of ozone and liquid strain was worth popularizing in the production of Flammulina velutipes.
