The special rapeseed fertilizer is prepared by a method comprising the following steps: conducting acidolysis on hairs to generate amino acid, then generating a micro element fertilizer liquid and an intermediate element fertilizer liquid chelated with amino acid, then sintering the quartz sands to prepare a fertilizer carrier, fermenting an organic fertilizer, mixing a nitrogen-phosphorus-potassium fertilizer, the carrier, the organic fertilizer and a vegetable insecticide, then granulating, and finally adopting the wintergreen oil for enveloping. According to the special rapeseed fertilizer provided by the invention, the fertilizer utilization ratio is improved obviously, the slow release effect is achieved, the fertilizer application amount is lowered, the pesticide residual is lowered, the output and the quality of winter wheat are improved, and the effects of turning waste into wealth and recycling economy are realized.

Description

A kind of fertilizer special for cole and preparation method thereof

Technical field

The present invention relates to agricultural fertilizer field, be specifically related to fertilizer special for cole and preparation method thereof.

Background technology

China is a large agricultural country, and rape is the main edible oil plant origin of China, and along with the continuous increase of world population, the demand of edible oil is more and more, and the yield and quality that how to improve rape is the inevitable requirement of social development.

Meanwhile, China is in the fast-developing stage, and the development of industrial or agricultural is very fast, and along with the development of industrial or agricultural, a large amount of agriculture and industry wastes is produced, and how to solve these agriculture and industry wastes, and realizing recycling economy is the development problem that current urgent need will solve.

Current rapeseed cultivation fertilizer used mostly is mineral manure, because of long-term excessive use mineral manure, nutrient imbalance, soil compaction, soil fertility decline, organic wretched insufficiency, the nutritional quality of rape declines, yields poorly, anti-adversity ability is poor, the lower degradation series of problems of oil, along with.

Therefore, develop a kind of brand-new fertilizer special for cole material, can improve yield of rape, improve oil product, can also solve agriculture and industry waste is an extremely urgent important affair simultaneously.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of fertilizer special for cole and preparation method thereof.Fertilizer of the present invention combines fertilizer, inorganic fertilizer, middle trace element and plant insecticide composition, formula rationally, nutrition more comprehensively, equilibrium, result of use is good, supplement nitrogen phosphorus potassium, organic matter, trace element, strengthen disease resistance of plant improvement soil, thereby improved the yield and quality of rape, solve the reasonable processing problem of agriculture and industry waste simultaneously, thereby realized the object of recycling economy.

The technical solution used in the present invention is as follows:

A kind of fertilizer special for cole, is characterized in that, is made up of the raw material of following weight part:

Agricultural stalk 40-50, coated carbamide 20-30, monoammonium phosphate 10-12, coating ammonium sulfate 10-12, coating Repone K 16-18, plant ash 20-30, manganous sulfate, ferrous sulfate, the each 1-2 of magnesium sulfate, zinc sulfate 0.1-0.5, boric acid 0.1-0.3, volcanic ash 10-12, charcoal 5-7, seal chinaberry fruit powder 3-4, tuber of stemona powder 3-4, bagasse 10-15, quartz sand 10-15, weathered coal 18-22, carboxymethyl cellulose 3-4,30% sulfuric acid 15-20, lime 5-10, animal hair 10-15, wintergreen oil 1-2.

The preparation method of described fertilizer special for cole, is characterized in that: comprise the following steps:

(1) first animal hair is added in 30% sulfuric acid, at 100-110 DEG C, be hydrolyzed 1-2 hour, generate amino acid, then add lime and be neutralized to Ph value 6.0-6.8, add again carboxymethyl cellulose, finally add manganous sulfate, ferrous sulfate, magnesium sulfate, zinc sulfate, boric acid to dissolve, at 90-105 DEG C of reaction 5-6 hour, generate micro-, the middle fertilizer liquid of chelating amino acids;

(2) by quartz sand after 400-500 DEG C of sintering 6-8 hour, add the wintergreen oil of about 1-2% to grind to form nanometer powder, then mix with moist plant ash, become fertilizer carrier;

(3) adopt During High-Temperature Composting fermentation fertilizer, get agricultural stalk, bagasse, weathered coal and add appropriate subtilis, mix rear heap fermentation, turning in 5-10 days once, leavening temperature 60-65 DEG C, fermentation time is 30-40 days, obtains when being covered with a large amount of white hyphas in heap the fertilizer completely that ferments, stand-by;

(4) fully mix by coated carbamide, monoammonium phosphate, coating Repone K co-grinding, then with volcanic ash, charcoal, the fertilizer then fermenting with step (3) mixes, and pulverizes, crosses 100-200 mesh sieve;

(5) after biotic pesticide being printed to chinaberry fruit powder and tuber of stemona powder and mixing, more fully mix with the material of step (2), (4);

(6) in chelating amino acids step (1) being made, micro-fertilizer liquid sprays in the mixture of step (5), fully mixes rear input granulator granulation thoroughly, finally sprays wintergreen oil and carries out coating, obtains fertilizer special for cole.

Fertilizer of the present invention is exclusively used in rape, every mu of fertilising 70-80kg.

Beneficial effect of the present invention:

(1) the present invention adopts acid hydrolysis feather etc. to generate amino acid, and then centering, trace element carry out chelating, and carboxymethyl cellulose has increased its chelate structure, in being conducive to, trace element effectively utilizes, in having reduced, the invalid release of trace element;

(2) quartz sand composition, after scaling loss, adds wintergreen oil and grinds, and has increased adsorption structure, and anti-caking, increases its dispersiveness simultaneously;

(3) in formula, increase inorganic slowly-releasing composition if volcanic ash and soil improvement composition are as bagasse, charcoal, be conducive to effectively slowly the discharging of fertilizer efficiency, rape fully absorbs;

(4) can effectively reduce soil disease and pest adding of plant insecticide composition, and not produce the residual phenomenon of agriculture, not develop immunity to drugs.

In a word, fertilizer formula of the present invention is scientific and reasonable is rich in the trace elements such as boron that rape growth must Shall, manganese, zinc, can obviously improve fertilizer efficiency utilization ratio.Can single-dose application, slowly effectively discharge, Fei Xiao Long, Hou Jin foot, utilization ratio is high, can reduce Effects of Fertilization Frequency, reduces rate of fertilizer application, reduces production costs, and reduces agriculture residual.Improve the yield and quality of rape.

Through evidence for many years, use fertilizer of the present invention and execute tradition fertilizer relatively, can increase production more than 30%; Quality improves, and the important trace element of needed by human body improves 10%, and harmful element reduces by 5%; Sugar degree improves a lot, and effectively promotes the synthetic of Methionin.
