The present invention achieves significant technique effect.
The invention carries out pre fermentation using saccharomycete to stalk composition, the metabolism production contained in tunning
Object is suitable for the fermentation of composite flora, and if directly composite flora is inoculated into stalk composition, due to fine contained by stalk
It ties up more difficult absorbed by compounding machine flora of the nutriments such as element to ferment, it is therefore desirable to which a large amount of substance easy to ferment of addition is increased into
This.The present invention first using the pre-fermented mode of saccharomycete will be difficult to the stalk to ferment carry out pre fermentation change and be easy to by
The fermentation composition that fermentative microflora absorbs significantly reduces the use of nutrient solution, reduces cost during the fermentation；Simultaneously
It solves the problems, such as that agricultural crop straw huddles to leave about.
The present invention is in pre fermentation, with stalk for main fermented material, while adding other a small amount of specific nutrients
Matter can make saccharomycete fast breeding, a large amount of saccharomycete then send out stalk in the Preliminary fermentation stage of saccharomycete
Ferment is degraded, and improves the success rate of saccharomycetes to make fermentation, and maintain lower fermentation costs.The material that pre fermentation obtains with it is compound
The specific nutrition material mixing of flora, the fermentation raw material can be wholly adapted to the fermentation of composite flora, and keep higher fermentation
And metabolic efficiency.During secondary fermentation, it is added to the carrier of montmorillonite, peat soil as active bacterial strain, improves bacterial strain
Load factor, ensure that the long period of activity of bacterial strain.During the present invention is handled after fermentation, sucrose, agar are introduced to ensure product
The activity of bacterial strain, and chitosan is introduced as protection adsorbent, ensure the survival rate of composite bacteria after fermentation.
The invention by Rhodopseudomonas palustris, bacillus mycoides strain, Bacillus amyloliquefaciens strain, false single
Six kinds of born of the same parents' bacillus strain, bacillus subtilis strain strains are compound, be capable of providing the required nitrogen of crop growth and
Inhibit the harm of harmful bacteria, virus for crop in soil, improves the structure of soil, create the soil suitable for crop root
Earth microenvironment.
A kind of preparation method raw material sources of composite microbe fertilizer of the present invention are extensive, and fermentation condition is mild, spawn activity
By force, it is used for a long time and can significantly improve soil microenvironment, increase fertility of land, achieve the purpose that increasing crop yield synergy.
