Embodiment 1-2 has prepared organic cultivating soil of good performance using agricultural organic waste, with reference to reality
Apply the application of aerobic microbiological leavening used in a 1-2, facultative microbe leavening in degraded agricultural organic waste
It is described further come the effect to the present invention, while also the property to the embodiment 1-2 organic cultivating soils prepared is carried out
Detection, specific experiment the results are shown in Table 1-2.
The degradation effect of the agricultural organic waste of table 1
| Degradation rate (100%) | Factor of created gase (L/kg) | |
| Embodiment 1 | 65% | 0.69 |
| Embodiment 2 | 63% | 0.65 |
As shown in Table 1, aerobic microbiological leavening, the facultative microbe leavening provided using embodiment 1-2 is being degraded
During agricultural organic waste, the degradation rate of agricultural organic waste can be set to reach more than 60%, factor of created gase reaches 0.65L/
More than kg, it can be seen that, aerobic microbiological leavening that embodiment 1 and embodiment 2 are provided, facultative microbe leavening are to agricultural
Organic waste has good degradation effect.
The organic cultivating soil physicochemical property of table 2
From table 2 it can be seen that the organic cultivating soil that embodiment 1-2 is prepared is for common garden mould, physicochemical property
More superior, the content substantial increase of nutrient, fertility is also greatly improved.After the organic cultivating soil maize planting of embodiment 1,
After the output increased 18% of corn, the organic cultivating soil maize planting of embodiment 2, the output increased 16% of corn, it can be seen that,
The organic cultivating soil soil physical chemistry superior performance that the present invention is prepared, fertility is strong, it is possible to increase crop yield.
In agricultural organic waste be rich in a variety of nutrients, also containing various trace elements, by fermentation after can give soil
Middle microorganism provides enough nutrients, moreover it is possible to accumulate for the nutrient needed for plant growth, the present invention uses aerobic fermentation first
Method is degraded to agricultural organic waste, on the one hand, advantage aerobic bacteria produces the fiber of heat endurance in degradation process
Plain enzyme, hemicellulase, lignoenzyme, amylase, glucose isomerase and other metabolites, destroy agriculture organic waste
The eucaryotic cell structure of gurry such as stalk, effectively facilitates the dissolution of the active ingredients such as starch, protein, cellulose, lignin, so that
The oxidation Decompositions such as protein, cellulose, the lignin of most of difficult degradation, to mitigate the pressure of follow-up and oxygen degraded, the opposing party
Face, the addition of advantage oxygen consumption bacterium shortens the aerobic fermentation time, so that aerobic fermentation maintains 60-70 for a long time as far as possible
Fast degradation agricultural organic waste at a high temperature of DEG C, overcomes that northern temperature is relatively low to cause asking for aerobic decomposition and inversion cycle length
Topic.
Requirement due to aerobic fermentation process to oxygen content is higher, although once mended every 1d turnings during the fermentation
It is oxygenated, but still inevitably there is ischaemia or anaerobism, makes aerobic fermentation insufficient, so, in aerobic fermentation
Carried out immediately and aerobe fermentation after end, support and promote and oxygen degradation reaction using (40 DEG C or so) of the temperature in aerobic fermentation latter stage
Progress；In addition, adding facultative microbe microbial inoculum when simultaneous aerobe fermentation, in the presence of facultative microbe microbial inoculum, accelerate
Agricultural organic waste rots, be conducive to and oxygen degradation cycle shortening, while can also be remaining by aerobic fermentation stage
Starch, protein, cellulose, lignin etc. it is degradable.Effect of the invention by aerobic facultative microbe microbial inoculum, it is right
Agricultural organic waste is fully fermented, and compensate for the deficiency of single aerobic or simultaneous aerobe fermentation, and not only fermentation efficiency is high, speed
It hurry up, it is thus also avoided that the operation of a large amount of oxygen consumption power consumptions such as artificial aeration.
River sand, peat, garden mould are added in fermentation finishes obtained organoclay, the physics and chemistry of organic cultivating soil is improved
Matter, adds its voidage and permeability；Meanwhile, inorganic fertilizer is also added in organoclay, is further improving soil
On the basis of physicochemical property, also non-plant growth provides enough nutriments, may advantageously facilitate plant growth, improves production
Amount.
It should be noted that when being related to number range in claims of the present invention, it is thus understood that each number range
Any one numerical value can select between two end points and two end points, due to step method and the embodiment 1-2 phases of use
Together, in order to prevent from repeating, description of the invention preferred embodiment, but those skilled in the art once know substantially
Creative concept, then can make other change and modification to these embodiments.So, appended claims are intended to be construed to bag
Include preferred embodiment and fall into having altered and changing for the scope of the invention.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these changes and modification.
