Abstract
The present invention relates to a method for producing a multi-element fertilizer by adopting plant straw ash residue. The method is characterized by comprising: taking 70-80 parts of plant straw ash residue, 3-15 parts of a waste sulfuric acid solution, and 5-29 parts of water, or taking 60-70 parts of straw ash residue, 5-30 parts of agricultural organic acid, citric acid residue, furfural residue or milk cow fresh manure, and 0-35 parts of water, completely and uniformly stirring, controlling the pH value of the uniformly-mixed material of 6.0-7.5 and the humidity of 30-40%, carrying out a composting reaction for 5-15 days, and drying and crushing the product after completing the composting to obtain the powdery multi-element fertilizer, or adding a binder having the amount of 0.003-0.1 time the product mass after completing the drying and the crushing, and carrying out granulation to obtain the granular multi-element fertilizer.
Description
Technical field
The present invention relates to a kind of method utilizing plant straw ash to produce multi-element fertilizer; be particularly useful for the disposal of ash and slag by generations such as burning, pyrolysis, gasifications in straw power generation process, belong to the fertile treatment and utilization technology of solid waste agriculture in agriculture environmental protection field.
Background technology
Traditional Land use systems of stalk is mainly as urban residents' fuel, animal-feed or direct returning to farmland.In recent years, along with rural economic development and farmers' income increase and the commercial energy resource such as coal, oil, gas universal, agricultural crop straw mainly as fuel has become waste or taken certain farmland to be piled up throughout the year, or on-site incineration, not only wastes ample resources, also serious environment pollution;
Straw power generation is the new way that a kind of stalk resource utilizes, no matter be as urban residents' life fuel or for batch production generating, all can produce 3-20% lime-ash in stalk pyrolysis, gasification, combustion processes.Stalk ash contains the multiple beneficial elements such as various plants essential element nutritive element and Si, Se such as P, K, Ca, Mg, Fe, Zn, Cu, large quantity research shows, use plant ash to the significant effect of increasing production of a lot of crop, in China's traditional agriculture, plant ash is a kind of important source of manure.In stalk ash, the biological effectiveness of plant essential element and beneficial element is general lower;
Because the plant ash nutrient form difference of different sorts stalk and differing temps burning is large, and the invalid state of many one-tenth, directly using if do not added process, its fertilizer efficiency can not be given full play to first, second may cause crop detrimentally affect.Summary of the invention
The present invention is directed to the low defect of plant nutrient validity that stalk ash is directly used and prior art processing produces, a kind of method utilizing plant straw ash to produce multi-element fertilizer is provided, the validity of fertilizer plant nutrient that the method is produced is high, not easily lost efficacy by soil fixing, suitable all kinds of soil application, and preparation process is simple to operate, be easy to promote;
Utilize plant straw ash to produce a method for multi-element fertilizer, it is characterized in that:
The method is main raw material with plant straw ash, and add the reaction of Industry Waste acid solution, agricultural organic and/or composting and can produce organic acid organic solid castoff, surplus is water, and control material pH value 6.0 ~ 7.5, humidity of materials controls 30 ~ 40%;
By above-mentioned material stirring, evenly rear composting reaction is after 5 ~ 15 days, and drying and crushing, obtains powdered fertilizer;
This powdered fertilizer is directly packed, or packs after the cakingagent granulation adding its weight 0.1 times;
Wherein, stir after the plant straw ash of 70 ~ 80 parts, 5 ~ 15 parts of spent acid solutions and the three kinds of component mixing of 5 ~ 29 parts of water, the reaction of sealing composting can obtain neutral multi-element fertilizer after 3 ~ 5 days;
Wherein, by 60 ~ 70 parts of stalk ash, 5 ~ 30 parts of agricultural organics or composting reaction can produce organic acid organic solid castoff and 0 ~ 35 part of water, stir, sealing composting reacts, within 5 ~ 10 days, obtain chelating multi-element fertilizer afterwards by after above-mentioned three kinds of components mixing;
It is one or more in feces of livestock and poultry, municipal sludge, domestic refuse or industrial organic waste residues that described composting reaction can produce organic acid organic solid castoff;
Described industrial organic waste residues is various microbiotic, zymin, alcohol, citric acid, furfural, monosodium glutamate, in the waste residue of discharging in sugaring or Chinese herbal and crude drugs preparations industrial production one or more;
Described agricultural organic refers to agricultural amino acid and agricultural humic acid;
Described plant straw ash refers to the lime-ash that agricultural crop straw, forest or agricultural processing fent are formed through burning, cracking, gasification;
Described Industry Waste acid solution refer to that Waste Sulfuric Acid, waste phosphoric acid, waste nitric acid, useless acetic acid, useless oxysuccinic acid or useless citric acid that chemical engineering industry, brewery industry or food-processing industry produce and these industries produce containing one or more in the waste liquid of multiple acidic component;
The present invention has distinguishing feature compared to existing technology:
1, the present invention makes lime-ash element be activated by adding mineral acid, or carry out retting fermentation generation organic acid or directly add organic acid (as amino acid, humic acid etc.) lime-ash Middle nutrition element Chelating state is activated by adding organic waste (as animal dung), therefore the activity of this fertilizer is strong, especially the formation of Chelating state, soil is not easily fixed, and improves plant recovery of nutrient in lime-ash;
2, by organic acid or mineral acid treatment or by adding organic waste retting fermentation and acid, make lime-ash pH drop to neutrality, therefore obtained fertilizer is applicable to all kinds of soil;
3, field test shows, the technology of the present invention produce lime-ash fertilizer than common stalk ash under every mu of consumption is 150kg condition, the crop yields 10 ~ 20% such as capsicum, tomato, radish, rape;
4, the present invention is also by adding cakingagent, carries out granulation processing to lime-ash fertilizer, is convenient to packed and transported and uses, and is particularly useful for agriculture extensive use of chemical fertilizer and the commercialization of a large amount of lime-ash that straw power generation produces;
5, raw material used in the present invention is agriculture and industry waste, and course of processing no waste produces, and is therefore that one is made a silk purse out of a sow's ear, and realizes the environmentally-friendly technique of waste resource recycling.
