Description

A kind of new-type fertilizer and production technique thereof
Technical field
The invention belongs to technical field of agricultural fertilizers, be specifically related to a kind of new-type fertilizer and production technique thereof.
Background technology
Production of manure is already through there being the history of over one hundred year; enter after 21st century; along with the development of agricultural modernization production; people look forward to fertilizer field can occur having multi-functional fertilizer, can improve the quality of the output of soil raising farm crop, enhances productivity; reduce and produce or improve working conditions; conservation of nature environment, is able to eat to healthy favourable people, non-harmful agricultural-food.
Plant-growth needs 16 kinds of elements, except N, and P, beyond K, also will to supplement in soil activation plant required in other oligo-elements, otherwise can cause in soil plant nutrition out of proportion, affect farm crop normal growth, gently cause empty producing, heavy No kernels or seeds are gathered, as in a year of scarcity due to physiological disease.If can appropriately use oligo-element, grain just can increase production, and what have can premature ripening and minimizing disease.Boron deficiency, Semen Brassicae campestris is bloomed and is not tied angle, and cotton has flower bud without flower, and corn lacks zinc, and Chlorosis in Fruit trees obtains yellowtop.But middle oligo-element major part is all metallic element, and its fertilizer is applied directly in soil and is easy to by soil fixing, validity and utilization ratio are all very low, various trace elements are carried out that reasonably compatibility is particularly important before using.In prior art, make fertilizer efficiency comprehensive by adding various oligo-elements, but it is higher to relate to cost, and can not adds the problems such as various elements comprehensively.
Current domestic field of fertilizer production, main fertilizer production technology has these three kinds of granulating methods, slurry process, fused mass granulating.Wherein granulating method and slurry process also have several processes such as dry method and wet processing of granulation, dry, cooling, screening, fragmentation, returning charge, tail gas except being configured to of raw material in production process, then just can enter packing of product process, corresponding technical process is long, investment is taken up an area large, production process energy consumption is high, and environment is caused to Different Effects.For fused mass granulating, because production process has metering and the mixing of raw material, the heating and melting of raw material, tower (revolution steel band) granulation, process of cooling, corresponding investment is taken up an area large, and production process energy consumption increases.
Summary of the invention
The present invention be directed to the defect of prior art fertilizer production technology, a kind of new-type fertilizer and the production technique thereof of proposition.The present invention, by effectively utilizing the organic waste materials of farm crop, in conjunction with microbial fermentation technology, provides a kind of new-type fertilizer, this fertilizer can improve Soil structure greatly, controls the loss in nutrient use procedure, makes fertilizer efficiency more lasting, there is higher yield of crops stable yields, the effect such as Miao Qimiao is strong.Production technique of the present invention has the features such as technical process is short, investment is taken up an area less, energy consumption is low, pollution-free.
For achieving the above object, the present invention is by the following technical solutions:
A kind of new-type fertilizer, it is prepared as follows and forms:
Maize straw is dried, then be ground into corn stalk powder with pulverizer, add in fermentor tank, toward the water that adds dregs of beans and 80-90 DEG C in fermentor tank, stir, in the time being reduced to 30 DEG C subsequently, add mixed bacteria liquid, under 100-200 rev/min of agitation condition, fermentation 36-40 hour, obtains fermented liquid; Wherein, the mass ratio of corn stalk powder, dregs of beans, water and mixed bacteria liquid is 5:2:20:1; Described mixed bacteria liquid is mixed according to the volume ratio of 1:1:1 by subtilis liquid, trichoderma harzianum liquid and azotobacter chroococcum liquid, and the concentration of three kinds of bacterium liquid is (2-3) × 10 7individual/ml.
Vermiculite power, the peat composed of rotten mosses, brown coal powder, zeolite powder and water are added in stirred pot according to the mass ratio of 3:2:1:1:10,300-500 rev/min is stirred 30 minutes, then enter retort, be heated to after 100 DEG C with the heat-up rate of 10 DEG C/min, insulation reaction 5-10 minute, be cooled to room temperature, obtain pasty state feed liquid;
According to pasty state feed liquid: the mass ratio of urea: monoammonium phosphate: Repone K: ammonium chloride: water=1:1:3:2:2:2 mixes, join in double-screw extruding pelletizing machine, in granulation process, tablets press template is selected the aperture of 3 millimeters, dicing machine is established in tablets press exit, bar shaped fertilizer is cut off, finally spray fermented liquid, stir, cryodrying control moisture content is 1-2%(mass/mass) left and right, pack and get final product; Wherein, the mass ratio of fermented liquid and pasty state feed liquid is 1:1.
Described fertiliser granulates diameter is 3 millimeters, and length is 3-6 millimeter.
The invention also discloses the production technique of above-mentioned new-type fertilizer.
Note, the bacterial classification of using in above-mentioned steps is the conventional bacterial classification of this area, and those skilled in the art can obtain its bacterium liquid according to its cellar culture method, are not innovative points of the present invention herein, do not describe in detail.Bacterial classification of the present invention all can be bought and obtain from commercial sources such as US mode culture collection warehousings (ATCC).
The beneficial effect that the present invention obtains mainly comprise following some:
The present invention, by the organic waste materials that effectively utilizes nature to exist, in conjunction with microbial technique, greatly reduces the turnover rate of fertilizer, has improved fertilizer efficiency;
In fertilizer of the present invention, add vermiculite power, the peat composed of rotten mosses, brown coal powder and zeolite powder etc., supplemented multiple nutriment, fertilizer efficiency is comprehensive lastingly, strengthens crop disease-resistant anti-adversity ability;
The present invention adopts microbial fermentation technology, and agricultural waste are carried out to organic decomposition, turns waste into wealth, and greatly provides cost savings;
The multiple-microorganism that the present invention selects adopts rational proportion, by symbiosis Relationship With Proliferation, has formed a complexity and stable microecosystem, and fixed nitrogen fertilizer conservation effectively, has improved fertilizer efficiency;
Production technique of the present invention has the features such as technical process is short, investment is taken up an area less, energy consumption is low, pollution-free.
