Abstract
The invention discloses a kind of Mushroom cultivation material sterilization process, it includes that sterilizing in autoclave will be put into after the culture material splitting containing outmoded sawdust, it further includes the dispensing stage before splitting step, and strong acid weak base salt is added into culture material, and the pH value for adjusting culture material is 4~5.For the present invention by adding strong acid weak base salt into compost, adjustment pH value is 4~5, and then improves hydrogen ion concentration, improves sterilization effect.
Description
Technical field
The present invention relates to field of edible fungus culture more particularly to a kind of Mushroom cultivation material sterilization process.
Background technique
Sawdust is early stage edible fungus culturing main raw material(s), as natural forest protection usage amount is reduced, gradually by corncob
It is replaced with cotton seed hulls.But the cultivation of the domestomycetes such as mushroom, agaric must use sawdust.The main component of sawdust is crude fibre
And carbohydrate, it is that the substance of carbon source is provided in formula.As the source of fresh sawdust is sharply reduced, people began to use
It goes to abandon air-dried sawdust or the wood powder wood fragments air-dried for many years in forest farm considers (i.e. outmoded sawdust) mushroom culture, but outmoded sawdust to be worth doing
Water imbibition is bad, and surface sees that moisture has reached standard when configuration, and actually sawdust does not suction moisture, there is a dry heart, and the dry heart
It is the non-conductor of heat, is difficult sterilizing thoroughly, will cause a large amount of pollutions, bring serious economic loss to mushroom grower.Therefore such as
What is urgently to be resolved in Mushroom cultivation material sterilization process ask to using compost of the outmoded sawdust as culture material to carry out sterilizing
Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of Mushroom cultivation material sterilization process.
Realizing the technical solution of the object of the invention is: a kind of Mushroom cultivation material sterilization process comprising will contain outmoded wood
It is put into sterilizing in autoclave after the culture material splitting of bits, further includes the dispensing stage before splitting step, into culture material
Strong acid weak base salt is added, the pH value for adjusting culture material is 4~5.
Further, the strong acid weak base salt includes any one in ferrous sulfate, frerrous chloride or aluminum sulfate.
Further, it when being put into sterilizing in autoclave, is first slowly heated and is heated up with slow fire, make compost internal and external temperature one
Cause, temperature be slowly reached as defined in after sterilising temp, keep 2h~4h, then with the bored pot 4h~6h of waste heat.Miscellaneous bacteria is in outmoded sawdust
State present in compost is other than mycelia, thallus, conidium state, and there are also the dormant states such as pod membrane, these suspend mode shapes
In a dormant state, unusual high-temp resisting high-humidity resisting is remaining for miscellaneous bacteria spore in dry compost for the existence form of state very high-temp resisting high-humidity resisting
The bored pot of heat can not only extend sterilization time, sterilize more thorough, and energy conservation.
The ability of miscellaneous bacteria high-temp resisting high-humidity resisting in acid environment is weak, the ability of high-temp resisting high-humidity resisting in the environment of alkalinity
By force.Outmoded sawdust materials pH is generally neutral to alkalinity, because of sawdust dehydration during desiccating, acidic materials reduction；And
And timber is denaturalized common caustic soda boiling timber, the sawdust material pH value being sawn into it in order to prevent in timber process in recent years
It is higher, and microorganism is not easy death when 6~8 pH.The present invention is 4 by adding strong acid weak base salt, adjustment pH value into compost
~5, and then hydrogen ion concentration is improved, hydrogen ion easily invades microbial cell, to change the physiological reaction of cell, it is dead to promote it
It dies, improves sterilization effect.
Specific embodiment
It elaborates below to present pre-ferred embodiments.
The present invention provides a kind of Mushroom cultivation material sterilization process comprising after the culture material splitting containing outmoded sawdust
It is put into sterilizing in autoclave, further includes the dispensing stage before splitting step, strong acid weak base salt is added into culture material, is adjusted
The pH value for saving culture material is 4~5；The strong acid weak base salt includes any one in ferrous sulfate, frerrous chloride or aluminum sulfate.
Further, it when being put into sterilizing in autoclave, is first slowly heated and is heated up with slow fire, make compost internal and external temperature one
Cause, temperature be slowly reached as defined in after sterilising temp, keep 2h~4h, then with the bored pot 4h~6h of waste heat.
The present invention is 4~5 by adding strong acid weak base salt, adjustment pH value into compost, and hydrogen ion easily invades micro- life
Object cell promotees its death, improves sterilization effect to change the physiological reaction of cell.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent process transformation made by bright description is applied directly or indirectly in other relevant technical fields, and similarly wraps
It includes in scope of patent protection of the invention.
