Abstract
The invention discloses oil shale semi-coke bacterial manure with a low cost and a preparation method thereof. The oil shale semi-coke bacterial manure is prepared from the following raw materials in parts by weight: 15-19 parts of oil shale semi-coke, 6-10 parts of monopotassium phosphate, 12-15 parts of attapulgite powder, 27-29 parts of seaweed powder, 22-25 parts of peat soil, 1-2 parts of microorganism supported matrix, 7-10 parts of beeswax and 34-36 parts of tobacco waste. The raw materials of the manure provided by the invention are mostly organic materials which are readily available and low in cost; compared with chemical fertilizers, the manure is less in dosage, lower in production consumption, and higher in output-to-input ratio; besides, running-away of a large quantity of nutrients is not caused due to a high utilization rate, and no harmful effect on surrounding soil and water is realized, therefore, investment required in environmental management is indirectly reduced, and the comprehensive economic benefit is increased.
Description
Technical field
The present invention relates to a kind of technical field of fertilizers, particularly a kind of oil shale semi-coke bacterial manure reducing production cost and preparation method thereof.
Background technology
Oil shale semi-coke is material remaining after oil shale distillation.Because resinous shale mineralization degree is higher, oil length is lower, utilizes, create a large amount of oil shale semi-cokes along with to a large amount of exploitations of resinous shale.And the stacking of oil shale semi-coke occupies a large amount of soils, and its quality is loosened after high temperature, after meeting with rain drop erosion and immersion, its various phenols, hazardous trace elements of containing, PAHs and alkyl homologue thereof can dissolve, flow into surface water with rainwater or penetrate in underground water, changing the hardness of water body, potential of hydrogen, organic concentration or element ion concentration etc., the ecotope of surrounding is impacted.Therefore, oil shale semi-coke adequately and reasonably to be developed and important.Oil shale semi-coke belongs to the material of vesicular structure, the present inventor utilizes this characteristic of oil shale semi-coke, with it for carrier, cultivate fixing for microbiobacterial agent on oil shale semi-coke, both shortened bacterial strain and fixed required time, and turn improved fixing effective bacterium quantity, to the lifting of fertilizer efficiency, there is active effect, as the substitute of industrial chemical fertilizer, have a good application prospect.
Summary of the invention
The present invention compensate for the deficiencies in the prior art, provides a kind of oil shale semi-coke bacterial manure reducing production cost and preparation method thereof.
Technical scheme of the present invention is as follows:
Fertilizer of the present invention is made up of the raw material of following weight part: oil shale semi-coke 15-19, potassium primary phosphate 6-10, attapulgite 12-15, seaweed powder 27-29, peat soil 22-25, microorganism immobilization matrix 1-2, beeswax 7-10, tobacco leftovers 34-36;
Described microorganism immobilization matrix is made up of following raw materials in part by weight: azotobacter chroococcum strain 3-5, cellulose degradation strain 1-3, silicate bacterial strain 1-3, quartz sand 10-14, sorghum flour 34-36, fern slag 52-58, jerusalem artichoke stem tuber 27-33, water are appropriate; Its preparation method is for squeeze out juice by jerusalem artichoke stem tuber, and gained juice is mixed with quartz sand, sorghum flour, fern slag, again mixture is placed in cylinder, roll under normal temperature 10-30 minute, take out in backward material and add azotobacter chroococcum strain, cellulose degradation strain, silicate bacterial strain, add suitable quantity of water keeps the water content of matrix to remain on 50-60% simultaneously, finally by gained matrix quiescent culture 2-3 week at 28-32 DEG C, obtains microorganism immobilization matrix.
The concrete steps of the preparation of described fertilizer are as follows:
(1) in microorganism immobilization matrix, add 5 times to the water of its quality, after filtration, leave filtrate, and slowly stir at 30-35 DEG C, obtain the composite bacteria suspension of homogeneous, for subsequent use;
(2) oil shale semi-coke pulverizer is pulverized, cross 50 mesh sieves, after obtaining uniform powder, at 750-850 DEG C, calcine 30-50 minute, for subsequent use;
(3) peat soil, tobacco leftovers mixing are placed in pulverizer are ground into trifling, then to mix with potassium primary phosphate, attapulgite, seaweed powder and step 2 gained oil shale semi-coke powder, granulation;
(4) step 3 gained particle is placed in sealed furnace water vapour heating 4-7 minute, after taking-up, naturally cools to room temperature;
(5) get 40% after beeswax intensification being melted and be sprayed at step 4 gained particle surface, then step 1 gained composite bacteria suspension spray pattern is evenly sprayed on particle, finally residue melting beeswax and leftover materials mixing are coated on particle surface;
(6) step 5 gained particle is placed in air-dry 2-3 days under 35-45 DEG C of dry ventilated environment.
The organic constituent in oil shale semi-coke can be removed in preparation process to the high-temperature calcination of resinous shale, avoid secondary pollution, the water-absorbent of semicoke and air drying can be improved, for the fixing fast of bacterial strain and drying provide condition simultaneously.
The heating energy carrying out water vapour to particle in preparation process improves specific grain surface and amasss, and improves the adsorptivity of particle.
Use beeswax can increase viscosity to the inside and outside coated of microbiobacterial agent in preparation process, promote the fixing of bacterial strain, simultaneously for microorganism provides carbon source, extend fertiliser granulates and preserve and time limit of service.
Beneficial effect of the present invention:
The raw material of fertilizer of the present invention mostly is organic material cheap and easy to get, consumption is few compared with chemical fertilizer, produce consumption low, there is larger product and throw ratio, simultaneously because utilization ratio is high, the loss of a large amount of nutrient can not be caused, surrounding soil water source is had no adverse effects, indirectly decrease the fund input needed for Environment control, improve overall economic efficiency.
