Description
Technical field
The invention belongs to fermentation technical field, and in particular to a kind of stover ferment agent and its preparation method and application.
Background technology
China produces about 700,000,000 tons of crop material per year, due to the transformation of country labor force transfer and tillage method, most of stalk
By on-site incineration or discarded.But, by stalk on-site incineration or discarded brought environmental pollution and problem of resource waste
Through as regulatory authorities and scientific research personnel's focus of attention.In stalk more than 60% be cellulose and hemicellulose, right and wrong
The biomass resource of Chang Youliang, by can be widely applied to the aspects such as feed, organic fertilizer, biogas after bioconversion.But, straw
The natural structure of stalk is extremely complex, and biotransformation efficiency is relatively low, and the difficulty for being directly used as the exploitation of above Related product is larger,
It is relatively costly.Therefore, it is a link mostly important during stalk resource is utilized stalk to be effectively treated, and is often adopted at present
With processing method be that stalk surrounding matrix is destroyed, such as：Composite construction depolymerization to hemicellulose and lignin, to increase
The enzyme-added contact with cellulose, and inhibition of the natural structure to substance transportation is reduced, while reducing the crystallization journey of cellulose
Degree.
The processing method of current stalk has physical treatment process, method of chemical treatment and biological treatment.
(1) physical treatment process：Wooden fibre can be to some extent destroyed using physical means such as high temperature, ultrasonic wave, microwaves
The natural structure of dimension, changes its stability.Stalk can realize the initial gross separation of each chemical constituent after steam blasting, and fiber becomes
Fluffy, specific surface area increase, hydrogen bond is reduced, structural rearrangement, is conducive to improving the accessibility of reagent, intensified response performance.But thing
Reason facture needs special equipment, and relatively costly, processing procedure has secondary pollution.
(2) method of chemical treatment：NaOH、H2O2, after the chemistry examination such as ammoniacal liquor processed stalk material, the fiber of stalk
There is a certain degree of destruction composition, form, crystal region, and stalk surface becomes loose, occur in that partial pore, the biology of stalk
Degradation property is improved.But chemical treatment can produce very serious secondary pollution.
(3) biological treatment：Fermentation process, stalk siliceous warty in appearance are carried out to stalk using efficient degradation bacteria
Structure comes off, and breakage on a large scale occurs in cell membrane, and whole stalk tissue becomes loose.Straw degradative bacterium can decompose each during it is organized
Polymer is planted, the lignin in stalk, cellulose and hemicellulose are decomposed into monomer or oligomer, improve its usability
Energy.Biochemical method cost is relatively low, does not have secondary pollution, but microorganism used therefor transformation efficiency in the biological treatment commonly used at present
Relatively low, process time is more long, and the content of organic matter for obtaining is low, have impact on the application and popularization of biological treatment.
The Chinese patent application of Application No. 201010509055.7 discloses a kind of direct decomposing and fermenting crops straws
The special microorganism composite bacterial agent for producing biogas and organic fertilizer is prepared and its application process.This special microorganism composite bacterial agent includes excrement
Terrible umbrella, mould, trichoderma, ink-cap (Coprinus atramentartius), after fermented culture, combination compounding is formed.But the composite bacteria fermentation stalk is produced
The content of organic matter that organic fertilizer is obtained is low and fermentation time is long.

The increase of the saprophytic animals and plants such as earthworm, effectively improves the situation of soil hardening, and it is loose porous that soil becomes, and is conducive to plant roots
The growth of system, meanwhile, the addition of the organic fertilizer has the effect of regulation soil acidity or alkalinity, reduces soil acidity, beneficial to plant
Growth.Secondly, the soil of organic fertilizer described in addition embodiment 1-4, the drought-resistant ability enhancing of the wheat of its plantation shows that addition should
The water holding capacity enhancing of the soil of organic fertilizer, the wheat of organic fertilizer described in addition embodiment 1-4 is compared to being not added with organic fertilizer
Wheat, its per mu yield substantially increases, and the per mu yield of organic fertilizer described in addition embodiment 3 reaches maximum 680kg/ mus, far above not adding
Plus 500kg/ mus of organic fertilizer, it is found that the height of per mu yield and organic fertilizer total nutrient and TOC in embodiment 1-4
Height it is closely related, with the increase of organic fertilizer total nutrient and TOC in embodiment 1-4, add corresponding organic fertilizer
Wheat per mu yield also correspondingly increase.Furthermore, the wheat of organic fertilizer described in addition embodiment 1-4 is compared to being not added with organic fertilizer
Wheat, its fruit growth cycle significantly reduces, and the fruit growth cycle for adding the organic fertilizer of embodiment 3 reaches minimum value 99 days,
Less than being not added with 120 days of organic fertilizer, it is found that the length in fruit growth cycle and organic fertilizer total nutrient in embodiment 1-4
And the height of TOC is closely related, with the increase of organic fertilizer total nutrient and TOC in embodiment 1-4,
The wheat fruit growth cycle for adding corresponding organic fertilizer also correspondingly reduces.Meanwhile, organic fertilizer is small described in addition embodiment 1-4
Wheat is compared to the wheat for being not added with embodiment 1-4 organic fertilizers, and Qi Mai Hui particles are bigger fuller.As can be seen here, with organic fertilizer
The growth of total nutrient and TOC, the growth cycle of wheat shortens and particle is fuller.In a word, it is small after soil improvement
Wheat can more fully absorb the nutrient and organic matter of machine fertilizer and effectively facilitate the growth of itself.
More than, the only present invention preferably specific embodiment, but the protection domain of invention is not limited thereto, any ripe
Know those skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in should all be contained
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by the protection domain of claims.
