Description
Technical field
The invention belongs to organic waste resource recycling and field of fertilizer production are and in particular to a kind of being based on concentrates natural pond
The organic fertilizer of liquid and its methods for making and using same.
Background technology
Anaerobic fermentation residues are biogas slurry, the two-part mixture of biogas residue, i.e. anaerobic digestion solution.Mainly by partly undecomposed
Organic substance, microbial metabolic products and newborn microbial cells composition, its comprehensive utilization not only can avoid secondary pollution, also may be used
Bring good economy, ecological environment and social benefit.The annual anaerobic fermentation residues of China (biogas residue, biogas slurry) about 3.85 hundred million t,
How to guarantee that the sustainable development of biological fuel gas engineering and the biogas engineering built can normally run, solve anaerobic digestion solution
Process extremely urgent with Utilizing question.At present, aspect is utilized mainly to apply (also field) pattern using direct in anaerobic digestion solution.
Because the moisture of anaerobic digestion solution is high, it is not easy to storage, transports, anaerobic digestion solution natural pond extensive use of chemical fertilizer (Fertilizer Transformed) difficult to realize,
Not only become restriction large industrialized biogas engineering economic benefit, the bottleneck of sustainable commercialized running, also become its money of restriction
The technical bottleneck that sourceization recycles.
For speeding up to agricultural modernization, China widelys popularize implantation in large scale and water-fertilizer integral, and puts into a large amount of moneys
Gold guiding agricultural implements irrigation and water conservancy, and especially north drought area irrigating facility development is very fast, and such as spray, drip irrigation set
Apply, objectively require supporting with it, inexpensive liquid fertilizer.The liquid fertilizer passing through at present is mainly solid-state Water soluble fertilizer
Material, raw materials for production a great number of elements potassium main source is potassium dihydrogen phosphate and potassium nitrate, and other raw materials are carbamide, MAP, nitre
Sour ammonium, chelated microelements, various raw materials carry out blending, stirring can achieve.Water soluble fertilizer is that one kind is completely molten
In water polyelement composite fertilizer it is desirable to can promptly be dissolved in the water, be beneficial to crop and absorb rapidly, and it absorbs
Rate is of a relatively high, is more crucially matched in the facilities such as modern spray drop filling, it is possible to achieve water-fertilizer integral.Certainly, water solublity
The administration of fertilizer is easy, can carry out fertigation with irrigation water (including the modes such as sprinkling irrigation, drip irrigation), reach water-saving and save fertile province
The efficiency of work.Water soluble fertilizer can be containing the whole nutrients required for plant growth, can be according to process of crop growth
Nutritional need feature carry out the formula of science so that its utilization rate of fertilizer is 2-3 times of conventional composite chemical fertilizer, reduce fertile
The waste of material.Secondly, water soluble fertilizer is a quick-acting fertilizer, and grower can be allowed to see effect and the table of fertilizer quickly
Existing, can according to crop difference growing way, fertilizer formula be made adjustment at any time.However, the restriction of water soluble fertilizer at this stage because
Element is mainly raw materials for production and production method, and such as potash fertilizer raw material sources, in potassium dihydrogen phosphate and potassium nitrate, due to expensive, are made
Solid-state Water soluble fertilizer is become to hold at high price.Import solid-state Water soluble fertilizer price typically at 30,000 yuan per ton about, domestic also per ton
20000 yuan about.Water soluble fertilizer is expensive, on the higher industrial crops of economic worth more using or be used for foliage fertilizer, and general
There is dissolubility, contain the mechanical admixtures such as water-insoluble it is impossible to adapt to irrigating facility liquid manure one completely in logical agricultural basis chemical fertilizer
The needs changed.In addition, the problems such as chronic administration Water soluble fertilizer often results in local secondary salinization.
At present, there is a problem of that moisture content is high, it is big to be dehydrated difficulty in the extensive use of chemical fertilizer of anaerobic digestion solution natural pond using aspect, in application side
Face is still more extensive, also lacks necessary theory support.And anaerobic digestion solution natural pond extensive use of chemical fertilizer poor product quality, single varieties, profit
Low with rate, added value is not high, and industrialization process is slow.Anaerobic digestion solution is rich in bioactive substance (organic substance) and crop must
The full price nutrient element of palpus, has the slow fertilizer efficiency feature having both of speed.Wherein, humus material is conducive to the work of soil microorganism
The dynamic formation with soil aggregate, improves potential ability and the stability of fertilizer provision from soil；The nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium unit
Element meets plant growth needs；Undegraded Organic substance provides N source and C source for soil microorganism, improves the biological of topsoil soils and lives
Property.Produce high efficiency organic-inorganic compound (conjunction) fertilizer, substrate, concentrate organic fertilizer etc. using biogas residue, biogas slurry, improve biogas residue, natural pond
Liquid scale process complete set technology system, not only can effectively solving Biogas Residues secondary pollution problem, realize resource
Change and utilize, promote traditional agriculture to produce and realize industrialization, commercialization and modernization, preserve the ecological environment, and agriculture can be promoted
Product safety production development, improves the international competitiveness of agricultural product.
Therefore, the organic liquid fertilizer with anaerobic fermentation residues as primary raw material for the exploitation, solves Water soluble fertilizer expensive
With the problems such as the secondary salinization of local to adapt to the needs of water-fertilizer integral, be to realize having of anaerobic fermentation residues high-value-use
Effect approach.Meanwhile, the composition of research anaerobic fermentation residues (biogas residue/biogas slurry), value, purposes and Land use systems, form biogas
The complete set technology system that engineering anaerobic digestion liquid scale is processed, determines the encouragement policy and Extension Model being suitable for China's national situation,
Promote circular agriculture construction, to realize biogas industry sustainable development significant.
