Abstract
The invention discloses a method for producing iron-rich organic fertilizer by utilizing waste tea residues. The method comprises the following steps of mixing tea residues produced by the tea processing industry with cow dung, sucrose and a decomposing agent in proportion for fermenting to form an iron-rich organic fertilizer which is rich in ferrous ion and chelation iron. The method disclosed by the invention utilizes industrial waste tea residues to produce the iron-rich organic fertilizer, can change waste into things of value, is beneficial to environmental protection, can improve effectiveness of the inorganic iron fertilizer at the same time, and is beneficial to crop growth.
Description
Technical field
Utilize and discard the method that tea grounds is produced rich iron fertilizer, relate to the production technology of organic fertilizer, particularly a kind of method of utilizing discarded tea grounds to produce rich iron fertilizer.
Background technology
Ferro element is one of necessary mineral nutrient element of growth and development of plants, the process such as synthetic at photosynthesis, respiration, nitrogen fixation, protein and the nucleic acid of plant materials is being brought into play very important effect, and iron deficiency certainly will cause the massive losses of yield and quality.One of iron deficiency, limiting factor that growth and development of plants is had the greatest impact arranged side by side with nitrogen stress and scarce phosphorus in agriculture production, according to statistics, the soil that the world has Potential iron deficiency accounts for 40% of world's cultivated area.
In recent years, the turnout of the deep processed products such as China's tea drink, instant tea and tea-polyphenol increases progressively fast and has produced a large amount of tea grounds, according to incompletely statistics, the waste tea quantity of slag of tens tea-polyphenol of China in 2003, production of instant tea enterprise is up to 160,000 tons, dispose if inappropriate, will certainly cause environmental pollution.
At present the conventional iron fertilizer of peasant is inorganic iron fertilizer, and take ferrous sulfate as main, but ferrous sulfate is manured into soil or foliage-spray after very easily oxidized inactivation, validity reduces, and has seriously reduced fertilizer efficiency, therefore must join and execute with fertilizer, just can obtain good result.This is because fertilizer includes organic bag and covers body and sequestrant, and iron is existed with more stable chelated iron form, the regulating effect to soil environment factor in addition, thereby reduced the oxidation inactivation of iron.
Research shows, in tea grounds, contain crude protein 17%-19%, and amino acid composition is more reasonable, Methionin and methionine content are respectively 1.5%-2% and 0.5%-0.7%, crude fiber content is 16%-18%, also contains a certain amount of VITAMIN, tea-polyphenol and trimethyl-xanthine and a small amount of tea saponin.On the one hand, the compositions such as the amino acid in tealeaves, tea saponin, trimethyl-xanthine, can with iron ion generation sequestering action, iron is existed with stable chelating state form, reduced oxidation inactivation risk; On the other hand, tea saponin itself is exactly a kind of good biological pesticide, can effectively kill the harmful organisms such as cutworm, Fushou spiral shell, and be that main material production fertilizer is out compared with feces of livestock and poultry, heavy metal content is low, can guarantee the security of product, avoids secondary pollution; If tea grounds and inorganic iron fertilizer are carried out to mixed fermentation, the two combination, can form a kind of novel rich iron organic fertilizer.
Summary of the invention
The object of the invention is to utilize trade waste tea grounds and agricultural wastes cow dung and inorganic molysite to carry out mixed fermentation, provide a kind of being manured into soil to be difficult for oxidized, biological effectiveness is high rich iron fertilizer and preparation method thereof.
The present invention is achieved in that
1. a method of utilizing discarded tea grounds to produce rich iron fertilizer, is characterized in that, it comprises the following steps:
(1) get the raw materials ready: tea grounds, cow dung is fully dry; And oversize material is pulverized, cross 20 mesh sieves;
(2) take material: by following weight part, take raw material: cow dung 20-40%, tea grounds 80-60%, sucrose 46-27%, decay agent 1-3%, inorganic molysite 15-25%;
(3) mixing and water adding: all mixing of materials is even, and mixing limit, limit Jia Shui, is adjusted to 55-65% by the water content of material;
(4) fermentation: carry out high temperature aerobic composting under the environment of temperature 50-70 ℃, fermentation 50-60 days, until material becomes thoroughly decomposed;
(3) dry: the material having become thoroughly decomposed is dried naturally to water content below 30%, and rich iron fertilizer is made.
Described inorganic iron fertilizer is iron vitriol.Described decay agent is commercially available straw decomposition agent, and its Ministry of Agriculture's registration number is that microorganism fertilizer (2010) faces word (1203) number, and operative norm is GB20287-2006.
Beneficial effect of the present invention:
1. the rich iron fertilizer that the present invention is prepared with tea grounds has solved current inorganic iron fertilizer and has used problem easy oxidized and that can not fully be absorbed by plant, is the effective measure that solve the Potential iron deficiency problem of current soil existence.
2. tea grounds is developed as rich iron fertilizer through stack retting, has opened up the new way of tea grounds recycling, has extended the industry chain (supply chain) of tea industry, can increase the economic benefit of tea industry.
3. discarded tea grounds is made full use of to the minimizing environmental pollution of turning waste into wealth.
4. in tea grounds, contained alkaloid, tea saponin etc. itself are exactly good biological pesticide, and agricultural pests is had to good preventive and therapeutic effect as cutworm, Fushou spiral shell etc.
5. ferrous sulfate is added in mixture and is fermented, the amino acid in tealeaves, tea saponin, trimethyl-xanthine etc. and the Humus composition that forms in mixed fermentation can with iron ion generation sequestering action, form stable chelated iron, be difficult for oxidized; Owing to can produce a large amount of organic acids in mixed fermentation process, make free ferrous ion in acid environment, make it to be difficult for oxidized, also can improve its fertilizer efficiency; In addition, the materials such as tea grounds, cow dung, sucrose during the fermentation, can produce large amount of organic matter, and wherein containing organic bag covers body, also can protect ferrous ion.That is to say, the rich iron fertilizer that the present invention produces can improve the biological effectiveness of ferrous sulfate greatly.
4, the rich iron fertilizer that the present invention is prepared with tea grounds, when supplementing ferro element for soil, has the effect of fertilizer concurrently, has increased the content of Soil Humus, can play the effect of improvement soil.
