Description

A kind of ox hair keratin coated slow release fertilizer strengthening fertility and preparation method thereof

Technical field

The present invention relates to fertilizer processing technique field, particularly relate to a kind of ox hair keratin coated slow release fertilizer strengthening fertility and preparation method thereof.

Background technology

China is a large agricultural country, and one of fertilizer most important means of production that are agricultural production, but owing to the utilization rate of common chemical fertilizer is the lowest, while waste resource, also result in serious environmental pollution.This nutrient release rate being primarily due to these fertilizer is too fast, causing crop to have little time absorption causes fertilizer efficiency loss serious, unreasonable use and low-quality Xing Yeshi China water body of fertilizer product receives pollution in various degree simultaneously, develops and uses slowly/controlled releasing fertilizer can solve this problem well.But the most at present, Slow/Controlled Release Fertilizers yet suffers from some problems to be needed to solve and perfect, problem as higher in production cost, that technics comparing is complicated and slow release effect is undesirable etc., therefore, is badly in need of that cost to be developed is relatively low, production technology simple and slow-release fertilizer that slow release and controlled-release effect match.Wherein, coated fertilizer is the key point that sustained release performance quality plays most important effect.China is animal husbandry big country, annual discarded animal hair keratin just can reach hundreds of thousands ton, and these natural keratin relatively closely and contain substantial amounts of disulfide bond due to this body structure, unless through the either physically or chemically process of some strength, it is to be otherwise difficult to degraded in the short time in natural environment, this large amount of natural keratin is discarded in natural environment, is that the waste to precious resources will also become a kind of solid waste and adversely affects environment.Corii Bovis seu Bubali process hides has used since technology, and the ox hair that hair saving process reclaims just is faced with how it is carried out the puzzlement of recycling treatment, because have passed through the effect of material and itself is mostly with the deepest color, is difficult to reapply wool industry.Therefore, if the most feasible technique can be set up utilize keratin, turned waste into wealth, will be had wide market prospect.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of ox hair keratin coated slow release fertilizer strengthening fertility and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of ox hair keratin coated slow release fertilizer strengthening fertility, is prepared by the raw materials in:

Ox hair 20-21, peat soil 40-44, Flos Rosae Multiflorae wood flour 60-65, Testa oryzae 55-59, Fructus Oryzae Germinatus 30-32, snail shell 20-22, perlite 18-20, shelled buckwheat 20-22, Ovum crusta Gallus domesticus 19-20, zinc sulfate 1-1.2, ascorbic acid 0.8-0.9, fatty acid methyl ester ethoxylate 0.2-0.3, sodium carbonate 0.2-0.3, mercaptoethanol 20-21, carbamide 18-19, sodium lauryl sulphate 3-4, glutamine transaminage 0.2-0.3, starch 3-4, the poly-vinyl alcohol solution 18-20 of 10%, the cmc soln 7-8 of 5%, formaldehyde 4-5, glycerol 5-6, Borax 0.2-0.3, microbial germ powder 2-2.5.

The preparation method of the ox hair keratin coated slow release fertilizer of described strengthened fertility, comprises the following steps:

(1) being mixed with fatty acid methyl ester ethoxylate, sodium carbonate by ox hair, the water adding 15%, rotary drum rotates 60 minutes, then rinses 10 minutes with flowing water, is dried, obtains defat ox hair；

(2) defat ox hair adding the water of 3 times, adds mercaptoethanol, carbamide, sodium lauryl sulphate, react 12 hours at 80 DEG C, then with the filter cloth suction filtering of 400 mesh, gained filtrate is cooled to when 40 DEG C add glutamine transaminage, and insulation stands 18 hours；

(3) starch is added 3-3.5 times of water heating in water bath 50 minutes at 75 DEG C, then the cmc soln with step (2) gained material and the poly-vinyl alcohol solution of 10%, 5% mixes, in 90 DEG C of heated and stirred 30 minutes, then formaldehyde, glycerol are dripped, Borax is added after reacting 30 minutes, continue reaction 15 minutes, obtain coating liquid；

(4) Flos Rosae Multiflorae wood flour, Testa oryzae, Fructus Oryzae Germinatus, snail shell, perlite, shelled buckwheat, Ovum crusta Gallus domesticus are pulverized, regulation to the water content that adds water reaches 40-45%, add microbial germ powder, heap vexed fermentation 25-30 days, the turning of 5-6 days period is once, then the raw material do not used with above-mentioned technique mixes, pelletize, dries to constant weight at 40 DEG C, the most uniformly sprays coating liquid, it is dried, to obtain final product.

The invention have the advantage that the present invention using ox hair keratin as coated fertilizer, the substantial amounts of sulfur wherein contained and nitrogen can supplement the nutrition of crops as sulfur fertilizer and nitrogenous fertilizer, cystine linkage in ox hair keratin can be reduced by the mercaptoethanol added, carbamide can compete hydrogen bond with polypeptide backbone, take the hydrogen bond in keratin molecule apart, salt type bond, the sodium lauryl sulphate added can avoid sulfhydryl-group activity to be oxidized to intermolecular disulfides, thus reach preferable solute effect, the keratin solution that ox hair obtains after treatment adds glutamine transaminage to be catalyzed keratin and crosslink reaction, thus it can be made to form the finest and close network structure in film forming procedure, improve film strength, reduce its dissolubility, thus enhance slow release effect, in addition, the present invention can improve soil property, strengthen fertility, fertilizer efficiency is long, pollution-free.
