微生物FBJ菌剂对双孢菇培养料发酵的影响

Effects of Microbial FBJ Agents on Fermentation of Cultivation Materials of Agaricus bisporus

[目的]立足于双孢菇(Agaricus bisporus)产业的发展,利用复合菌剂,促进秸秆发酵,减少发酵时间,提高发酵料品质,生产出优质的双孢菇。[方法]发酵料配方中稻草、猪粪、菜籽饼、熟石膏的用量分别为3 000、2 200、240、240 kg,其中试验组添加50 kg菌剂,对照组不添加。7月19日进行混合预湿并进一次发酵隧道,7月25日第一次翻料,8月1日第二次翻料,8月6日进二次发酵隧道,8月12日出二次发酵隧道。[结果]接种微生物菌剂可以缩短秸秆发酵达到高温的时间,延长高温持续的时间;可以在秸秆一次发酵过程中积累更多的高温微生物,用以分解秸秆中的复杂有机物;可以获得生产需要的质量更优的成品发酵料(二次发酵料)。[结论]该研究可为提升我国双孢菇和有机肥生产的水平提供参考。

[Objective] The aim was to promote straw fermentation,reduce the fermentation time,improve the quality of fermentation materials,to produce good quality Agaricus bisporus by using compound agents based on its industry development.[Method] Among the fermentation materials,the use amount of rice straw,pig manure,rape seed cake and plaster of paris were 3000,2200,240,240 kg,resp.,besides them the trial group was added into 50 kg agents,while the control group was not added into anything.The mixing and pre-wetting and going into the first fermentation tunnel was both in July 19,the first turning over and mixing was in July 25,the second turning over and mixing was in August 1,the going into the second fermentation tunnel was in August 6,and the getting out the second fermentation tunnel was in August 12.[Result] Microbial agent inoculation reduced the time reaching to the high fermentation temperature,lengthened the duration of high temperature ; accumulated more high-temperature microbes during the first fermentation of rice straw to decompose the complex organics ; got needed finished fermentation material（the second fermentation material） with better quality.[Conclusion] The study provides a reference for improving the production level of Agaricus bisporus and organic fertilizer.
