Organic fertilizer additive and preparation method thereof
Technical field
The present invention relates to fertilizer additive technical field, especially a kind of organic fertilizer additive and preparation method thereof.
Background technology
China be one populous, the large agricultural country of land resources deficiency can be ploughed, support the population accounting for the world 21% with the arable land accounting for the world 9%.The country that also still fertilizer generates and usage quantity is maximum in the world of China, wherein nitrogen fertilizer production and usage quantity rank first in the world, and the arable land accounting for the world 9% but consumes the fertilizer accounting for the world 30%; Its reason is that the utilization rate of fertilizer of China is lower; The existing fertilizer for plant is mainly:
Nitrogenous fertilizer: namely with the chemical fertilizer that nitrogen nutrition element is main component, comprises bicarbonate of ammonia, urea, pin ammonium, ammoniacal liquor, ammonium chloride, ammonium sulfate etc.;
Phosphate fertilizer: namely with the chemical fertilizer that phosphorus nourishing element is main component, comprise normal superphosphate, fused(calcium magnesium)phosphate etc.;
Potash fertilizer: namely with the chemical fertilizer that potassium nutrition element is main component, use few at present, principal item has Repone K, potassium sulfate, saltpetre etc.;
Urea fertilizer: comprise carbonyl diamine, carboxamide, urea;
The existing following problem of these fertilizer:
(1), inorganic pollutant, the mainly heavy metal contamination such as lead, chromium, mercury, cadmium, arsenic, it pollutes source, and mainly starting material adopt raw mineral materials, production spent acid, the rubbish, mud, feces of livestock and poultry etc. of heavy metal contamination produces that fertilizer causes.
(2), organic pollutant, mainly contain phthalate, nitro-aromatic, polycyclic aromatic hydrocarbons and halohydrocarbon etc., its source mainly mud, agricultural crop straw etc., the pollution of the tail gas that agricultural crop straw is easy to be subject to agricultural chemicals, weedicide and automobile, tractor discharges, this also indirectly have impact on the safety of fertilizer;
(3), antibiotics, China as the annual consumption of the duomycin of fodder additives and terramycin respectively up to 1000 tons with about 7000 tons, antibiotic remains serious harm HUMAN HEALTH in animal-derived food product, but, in animal cultivation, the usual overwhelming majority (80%-90%) of a large amount of various microbiotic used is drained with fecaluria with medicine original shape, and some veterinary drug has more high toxicity with the meta-bolites after ight soil discharge; The livestock waste such as pig manure, chicken manure is widely used in agriculture production usually used as fertilizer, inputs antibiotic quantity in soil every year thus and is not even second to agricultural chemicals, enter food chain by soil and fertilizer;
(4), pathogenic bacteria and worm's ovum, derive from and add untested microbial strains, human or animal can be caused to catch, nearly ten years due to the continuous expansion of bio-feritlizer new variety, production bacterial classification increases current kind more than 100, during bacterial classification uses, unsafe factor is also expanding gradually, likely flows into production link to the bacterial classification that people, animal and plant are harmful to;
(5), other source of pollution: after the chain of events such as Sanlu milk powder, melamine waste residue can be used for chemical fertilizers production, cause the concern of some scientific research departments, expert and fertilizer enterprise, researchist is had to test discovery, after using trimeric cyanamide, the root of Chinese cabbage and leaf all can detect melamine molecule, and this shows that the waste residue producing trimeric cyanamide can not directly as Term Fertilization.
Summary of the invention
Problem to be solved by this invention is to provide the organic fertilizer additive and preparation method thereof of a kind of no pollution, pure natural that utilization ratio is high.
In order to solve the problems of the technologies described above, the technical scheme adopted is: its composition includes the raw material of following weight percents: Radix Glycyrrhizae 2%, dry root of kudzu vine branches and leaves 2%, dry Wild Chrysanthemum 2%, oligosaccharides 1%, dry yeast 1.5%, water 91.5%.
The preparation method of this organic fertilizer additive, comprises the steps:
(1), clean Radix Glycyrrhizae, dry root of kudzu vine branches and leaves, dry Wild Chrysanthemum being put into temperature is that the boiling water of 100 DEG C soaks 4 hours;
(2), soaked after, the residue of the Radix Glycyrrhizae in soak solution, root of kudzu vine branches and leaves and Wild Chrysanthemum and contaminant filter are gone out;
(3), by step (2) gained filtrate deposit and leave standstill 20-30 minute in the cool, put into dry yeast and oligosaccharides ferments, ferment after 30 days, formation tart flavour, to obtain final product.
The present invention compared with prior art, has following beneficial effect:
1, various plants mixing is adopted to soak, and fermented liquid is obtained as organic fertilizer additive after soak solution ferments, full nutrition can not only be provided for farm crop, and fertilizer efficiency is long, can increase and upgrade the soil organism, promote microbial reproduction, improving physico-chemical property and the biological activity of soil, is the Main Nutrients of pollution-free food production; And greatly improve utilization rate of fertilizer, the turnover rate of fertilizer nutrient is reduced, promotes the development of plant husbandry, thus reach the object improving crop yield, afforestation ecological environment.
2, the wide material sources of this additive, resource is easy to get, and production process is pollution-free, is beneficial to suitability for industrialized production, the organic fertilizer additive produced by present method, with low cost, pollution-free.
Embodiment
Below in conjunction with specific examples, the invention will be further described:
Embodiment 1:
(1) weighing by weight percentage: Radix Glycyrrhizae 2%, dry root of kudzu vine branches and leaves 2%, dry Wild Chrysanthemum 2%, oligosaccharides 1%, Dan Baoli dry yeast 0.1%, water 92.9%;
(2) Radix Glycyrrhizae taken, root of kudzu vine branches and leaves, chrysanthemum are cleaned, put into temperature be 100 DEG C boiling water soak 4 hours;
(3), after having soaked, the residue of the Radix Glycyrrhizae in soak solution, root of kudzu vine branches and leaves and Wild Chrysanthemum and contaminant filter are gone out;
(4) filtrate deposited and leave standstill 20 minutes in the cool, put into dry yeast and oligosaccharides ferments, ferment after 30 days, formation tart flavour, to obtain final product.
Application with organic fertilizer additive:
Organic fertilizer additive obtained in embodiment 1 is sprayed in the manioc waste of the filter mud in sugar refinery, the brewer's grains of brew-house, starch factory; Ratio is the organic fertilizer additive that 1 ton of filter mud or brewer's grains or manioc waste prepare 1 kilogram; Filter mud, brewer's grains or manioc waste can be made after 5 ~ 7 days without any peculiar smell, filter mud or manioc waste or brewer's grains spontaneous fermentation after one month, moisture reaches 20 ~ 25%; The organic fertilizer be made into is applied to the plantation in plant, vegetables, crops, can not only provide full nutrition, and fertilizer efficiency is long for farm crop, can increase and upgrade the soil organism, promote microbial reproduction, improving physico-chemical property and the biological activity of soil, is the Main Nutrients of pollution-free food production.
