Description
Technical field
The present invention relates to fertilizer, particularly a kind of bio-organic fertilizer.
Background technology
From the nineties in 20th century, some R&D institutions of China and enterprise in succession research and production one class are collectively referred to as the product of ＂ biological organic fertilizer ＂ and put on market.Because this kind of fertilizer product research and production original intention integrates organic fertilizer and bio-feritlizer advantage, both increasing both production and income was conducive to, be conducive to again getting fat soil, improve soil micro-ecosystem system, reduce mineral manure consumption, improve and improve quality of agricultural product, meet the direction of China's agricultural sustainable development and pollution-free food production, this obtains and develops fast for several years.
Biological organic fertilizer refers to microorganisms with specific functions and is mainly originate and have the fertilizer of microbial fertilizer and fertilizer effect through the class that harmless treatment, the organic materials that becomes thoroughly decomposed are composited concurrently with plant and animal residues (as fowl and animal excrement, agricultural crop straw etc.).
Along with the sustainable development of the ecological agriculture, the enthusiasm that people develop biogas ecology agricultural is more and more higher, and the purposes of natural pond slag is also exploited gradually.Organic matter, humic agent, micronutrient element, multiple amino acids, enzyme and beneficial microorganism is rich in the slag of natural pond.Quality is loose, soil moisture conservation performance is good, potential of hydrogen is moderate, after becoming thoroughly decomposed and being produced into fertilizer, can play the effect of well improvement soil.Owing to being rich in organic matter etc. in the slag of natural pond, therefore slag aerobic compost in natural pond produces a kind of main trend that bio-feritlizer becomes natural pond Slag treatment gradually.
There is a very large problem in the direct aerobic compost of natural pond slag, be exactly the loss that the volatilization of ammonia causes nitrogen, this not only can reduce agricultural value, also can produce the new problem of environmental pollution such as serious stench, acid rain.
Straw charcoal itself has adsorptivity.Biomass straw powdered carbon and natural pond slag are carried out mixing becoming thoroughly decomposed and ferments, by the feature of its absorption, slowly-releasing, the loss of its nutritive substance can be reduced, improve utilization rate of fertilizer, the effect of soil improvement function and fertilizer synergistic can be taken into account simultaneously.But so far there are no how utilizing biomass straw powdered carbon, prepared by natural pond slag, reduces environmental pollution, improvement soil, improve the open report of crop yield biological organic fertilizer.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the present invention is just to provide a kind of bio-organic fertilizer, can effectively solve minimizing environmental pollution, the problem of improvement soil, raising crop yield.
The technical scheme that the present invention solves is, this organic fertilizer is by following mass ratio range: biomass straw powdered carbon 40-50%, natural pond slag 45-50%, wilkinite 0.05%-0.1%, nitrogenous fertilizer 0.5%-2%, phosphate fertilizer 0.5%-2%, potash fertilizer 0.5%-2%, biological deodorant 0.1-0.3% and wood vinegar 0.5%-1.5% make, wherein, by crops stalk crushing to 1-5cm, be encased in cracker, cracking is carried out at 300-1100 DEG C, obtain biomass straw charcoal, pulverize, cross 60-100 mesh sieve and become biomass straw powdered carbon; In 19-25 DEG C of heliogreenhouse, by biomass straw carbon dust and natural pond slag mixing and stirring, add biological deodorant, fermentation, at ventilation bottom fermentation 7-10 days, carries out turning, continues fermentation 7-10 days, become block mixture after turning; Pulverized by block mixture, cross 40 mesh sieves, then add the wilkinite as shaping assistant and nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, limit is stirred, and limit atomization sprays into wood vinegar, mixes, powdering or granulation;
Residue (known technology) after described natural pond slag straw-sludge anaerobic ferment for methane;
Described biological deodorant is the biological deodorant of beneficial microorganism fermentation, known commercially available prod, as the product etc. that Beijing Lay bit Environmental Protection Technology Co., Ltd produces;
Described cracker is the one in the slow cracking still of biomass, biomass gasifying furnace, biomass flash pyrolysis still, known commercially available prod.
Abundant raw material of the present invention, cost is low, easily produces, and uses conveniently, effective, effectively can reduce environmental pollution, and improvement soil, raising crop yield, be that one on fertilizer is innovated greatly, economic and social benefit is huge.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
