Material culture of agaricus bisporus fermentation back storage utilizes method with reduction
Technical field
The present invention relates to the culture technique of agaricus bisporus, preserve and reduce the method for utilizing after the fermentation of particularly a kind of material culture of agaricus bisporus.
Background technology
Agaricus bisporus is a kind of typical saprophytic fungus, and natural wild agaricus bisporus often is grown on the excrement grass organic matter that becomes thoroughly decomposed, and therefore often is called as straw rotting fungus.Since the artificial cultivation agaricus bisporus so far, agaricus bisporus still be grown in contain excrement, the grass composts or fertilisers of cultivating on.Because the poor ability of agaricus bisporus mycelia decomposition of cellulose and lignin, directly decompose and utilize composts or fertilisers of cultivating to have any problem.Therefore, material culture of agaricus bisporus is fermentation reactor system in advance, allows a large amount of breedings of beneficial microbe such as the plain decomposer of some fibre, and fermentations such as straw in the compost, cow dung are decomposed, and becomes nutriment simple in structure, that agaricus bisporus absorbs easily.Metabolite of microorganism and mycoprotein also become the required nutrient of agaricus bisporus growth.Composts or fertilisers of cultivating can kill off the insect pests and assorted bacterium by the composting hot fermentation simultaneously, improves the physicochemical character of composts or fertilisers of cultivating.By biology, the chemical reaction of composts or fertilisers of cultivating fermentation process, produce the culture matrix that is suitable for the agaricus bisporus growth with good physicochemical character.
Early stage composts or fertilisers of cultivating fermentation reactor system is called long-term fermentation, at the outdoor composting that will carry out 28~30 days (d), wants turning during this period 5~6 times.There is the people to study successfully the secondary fermentation technical matters abroad, is about to the composting composts or fertilisers of cultivating and is divided into one time fermentation and two stages of secondary fermentation in nineteen fifty.One time fermentation is that the raw material of preparation are prewetted, and mixes, and piles shape outdoor building in accordance with regulations, by microbial activities, makes compost produce 60 ℃~80 ℃ high temperature, by turning several times, makes it even.Secondary fermentation is after the composts or fertilisers of cultivating one time fermentation finishes, in cultivating chamber or special facility, strictly control temperature and air, utilize thermophilic actinomycete at 45 ℃~55 ℃ fermentation maturities, four-stage such as this process is by temperature balance, sterilization, become thoroughly decomposed, cooling carries out.One time fermentation needs 12~16d, and secondary fermentation needs 7~12d.
Had the people to introduce material culture of agaricus bisporus secondary fermentation technology at home afterwards, and made the agaricus bisporus per unit area yield increase substantially, average per unit area yield improves 20%~30%.During the last ten years, agaricus bisporus secondary fermentation technology obtains large tracts of land and promotes on a large scale, and the development that promotes domestic agaricus bisporus production has been produced important function.But, the fermentation of the composts or fertilisers of cultivating of present domestic agaricus bisporus production exists still that batching is extensive, the nutrient proportioning is unreasonable, operation (pasteurization, the temperature of becoming thoroughly decomposed do not reach requirement, deficiency of time etc.) lack of standardization situation, also have the composts or fertilisers of cultivating of many regional culture agaricus bisporuses still to continue to use backward long-term zymotechnique, cause the composts or fertilisers of cultivating maturity poor, assorted bacterium, worm's ovum are seriously polluted, have had a strong impact on output.Because the mushroom farming disperses the composting composts or fertilisers of cultivating, rural environment is exerted a certain influence simultaneously.
Because agaricus bisporus production is subjected to the restriction in season, make the composts or fertilisers of cultivating fermentation reactor system time comparatively concentrated, and the labour of agaricus bisporus production base relatively lacks, so just produced comparatively outstanding contradiction.Simultaneously, the feed of mushroom compost batch production production and peasant cultivating bisporous mushroom under natural climate condition is concentrated needs the contradiction of material (in annual early October~early December) also comparatively outstanding.Therefore, exploitation material culture of agaricus bisporus fermentation back storage and reduction utilize technology, are to solve lack of labor and the composts or fertilisers of cultivating fermentation reactor system time comparatively concentrates, agaricus bisporus is produced and concentrated the effective ways that need the contradiction that (confession) expect season.
