Since intensive ox plant mostly uses greatly water to rush the cleaning up excrement mode of excrement, the moisture content of waste is made often to be up to 82.6%
~95.7% (w/w), much higher than the moisture content (55%~65% (w/w)) that usual compost is suitable for, such high-moisture percentage cow dung
Using common compost treatment mode, even if being all difficult to ferment at 10 months or more, treatment effeciency is extremely low.And common
Processing mode not only causes greatly to pollute to water resource, land resource, causes pest and disease damage to crops, but also can be to people and animals
Propagate various diseases.
But cow dung itself contains a large amount of organic matters abundant again, contains crude protein 10%-20%, crude fat in dry cow dung
1%-3%, crude fibre 15%-30%, nitrogen-free extracts 20%-30%, additionally containing a great number of elements needed for crop, as N,
P and K etc..If cow dung is not perfect without fermentation process or fermentation process, will cause the secondary fermentation of cow dung so as to cause
The generation of burn seedlings phenomenon, long-time service possibly even will lead to that not even a blade of grass grows, can bring instead to agricultural production serious bad
It influences, and there is also germ and helminths in cow dung, if not making it sufficiently ferment, can infect crops, harmful to human
Health；It but is good organic fertilizer resource if carrying out processing appropriate and utilizing.
Solve the problems, such as that high-moisture percentage cow dung is difficult to handle and generally use following processing mode, (1) in advance heap cow dung into
Row dehydration；(2) largely dry conditioner is added to adjust moisture content to zone of reasonableness.But this can also give practical compost
Production brings new problem: (1) increasing processing equipment and produce higher energy consumption and processing cost, make natively to invest huge
Greatly, compost enterprise unable to make ends meet is difficult to maintain；(2) desiccant largely used causes the fertilizer efficiency of organic fertilizer to decline, increases
The use cost of farmer, causes quality decline.
Therefore, if can design one kind can take into account the advantage of common organic fertilizer preparation process and evade dry, deodorization
The deficiency of high expensive caused by journey, moreover it is possible to avoid environmental pollution accident, realize crops healthy growth and effectively processing height
The problem of moisture content cow dung；This to science improve cow dung processing capacity, further water conservation, land resource, air resource,
Saving agriculture production cost, it has great promotion effect.

By comparative example 1 and comparative example 1 as can be seen that (1) in formula without diatomite ingredient when, anaerobic fermentation
Total fermentation time with aerobic fermentation is 47 days~60 days.After introducing diatomite ingredient in formula, anaerobic fermentation and aerobic hair
The total fermentation time of ferment is 4 days~7 days, and fermentation efficiency is greatly improved.(2) diatomite and starch are simultaneously as hair
Ferment start agent with use merely starch as fermentation starting agent compared with, the fermentation starting time only needs 0.5 small in embodiment 1
When, and 5 hours or more are needed in comparative example 1, the fermentation starting time greatly shortens, and creates good item to promote fermentation efficiency
Part.If certainly it should be pointed out that use diatomite as adsorbent merely, since shortage starch is as fermentation starting agent,
Fermentation can not start.This further illustrates that the mutual cooperation role of diatomite and starch is far longer than
The sum of property.

Purpose be to allow starch to be sufficiently mixed with EM stoste, and starch can be used as fermentation starting agent, and fermentation can be made in the short time
Interior starting.Probiotics could be made effectively to be fermented under the suitable conditions when mixing for second in this way.It is sent out in comparative example 2
Ferment is unsuccessfully because when using traditional Organic fertilizer production method, and probiotics starts fermentation not yet and just had received from height
The pollution of miscellaneous bacteria in moisture content cow dung, so as to cause fermentation failure.Therefore this patent is using the way mixed twice, creatively
Diatomite and starch are mixed, the advantage that the advantage and starch for taking full advantage of the porous structure of diatomite are effectively fermented, and
The two is combined, fermentation efficiency is substantially increased, its effect is made to be far longer than the sum of the two property.
To further illustrate actual effect of the invention, below two kinds of organic fertilizer to embodiment 1 and comparative example 1 and
The fertilizer efficiency of common organic fertilizer carries out a comparative experiments.
In late April, 2017 in Hubei Province, stone nozzle town, Yingshan County cogongrass field group, implements 3 mu of plot (1 mu/block), 3 ground
Spring maize is sowed on block respectively.Corn applies fertilizer when taking out seedling to 20 centimeters or so, other pest and disease damages and irrigates processed as usual.
Wherein common organic fertilizer experimental plot is 1 mu, and apply fertilizer 200kg per acre, is early August to harvest to obtain corn after 120 days
372.4kg, corn stover has been withered when harvest, illustrates that soil already without fertilizer efficiency, but detects that soil is not hardened.
Wherein the organic fertilizer experimental plot in this comparative example 1 is 1 mu, and apply fertilizer 200kg per acre, is early August harvest after 120 days
Obtain corn 391.3kg, corn stover has been withered when harvest, illustrates that soil already without fertilizer efficiency, but detects that soil does not have
It is hardened.
Wherein the organic fertilizer experimental plot in the present embodiment 1 is 1 mu, and apply fertilizer 140kg per acre, is early August harvest after 120 days
Obtain corn 435.6kg, leaf when harvest in corn stover is still cyan, and illustrating soil, still there are also fertilizer efficiency, and detect
It is not hardened to soil.
By embodiment 4 it can be seen that the organic fertilizer fertilizer efficiency in embodiment 1 is much higher than comparative example 1 and common organic fertilizer.Its
The reason is that the diatomite in formula bulk fermentation is absorbed in (3) step needed for nutriment, entire fermentation process do not have
The loss of effective component, so that the fertilizer efficiency of organic fertilizer produced by the invention is effectively maintained.Therefore having in embodiment 1
The fat effect of machine is preferable.
