Abstract

The invention relates to a preparation method of a novel biological organic fertilizer. The method which can effectively solve the loss of available nutrients in the biological organic fertilizer caused by high temperature in a drying link and has the characteristics of practicality and maneuverability through adding a novel high-quality protein raw material allows the effects of changing harms into goods and wastes into valuables to be reached. The preparation method is simple and effective, costs low and is convenient for popularization. The purpose of the invention is realized with the following technical scheme that the preparation method of the novel biological organic fertilizer comprises the following steps: pretreating livestock and poultry manure, a biogas slurry and biogas slag in a biogas digester, animal fur leftover or other foods containing protein components, and medicine leftover which are treated as raw materials; carrying out multiple fermentation, dehydration, and composting decomposition; crushing, screening, granulating, and drying through metering according to a required proportion after products are qualified by harmless index detection, wherein the drying process is self-designed inverse secondary drying, and the products are rapidly cooled to normal temperature by a shock fluidized bed device; and carrying out screening, low temperature coating and bacterium adding, examining, packaging and metering, and finished product warehousing.

Description

A kind of bio-feritlizer and preparation method thereof

Technical field

The present invention relates to a kind of bio-organic fertilizer and preparation method thereof, particularly a kind ofly contain the food, medicine tankage of protein ingredient as raw-material a kind of bio-organic fertilizer and preparation method thereof with liquid natural pond, the natural pond slag in feces of livestock and poultry, the methane-generating pit, animal skin tankage or other.

Background technology

Current, use the problem of environmental pollution that chemical fertilizer caused more and more to get more and more people's extensive concerning.According to pertinent data, in the eutrophication in the main lake of China, from the influence of agricultural non-point pollution even surpassed industrial pollution.After chemical fertilizer is manured into soil, except that the part that is absorbed by crop, also have considerable part by the loss of approach such as seepage, volatilization and nitrification and denitrification, therefore will cause pollution inevitably, at the energy with also be a kind of waste economically environment such as atmosphere, water body and soil.Bio-organic fertilizer is expired fixed nitrogen as spreading sieve, potassium class bio-feritlizer is released in phosphorus decomposing and use, not only can reduce the usage quantity (use as described above spread the full bio-feritlizer of sieve can reduce by 10～35% chemical fertilizer) of chemical fertilizer, and under the effect of useful active bacterium, its fixed nitrogen directly is stored in root system of plant, simultaneously phosphorus, the potassium that exists in the soil is activated, be converted into the absorbent available phosphorus of plant, effective potassium.Comparatively speaking, drop to the chance of environmental pollution minimum.

Generally adopt the forward preparation method of type primary drying in the present known bio-organic fertilizer, both the material after granulating working procedure directly entered drying cylinder, protein resource in so easy destruction organic fertilizer raw material, thus available nutrient reduced in a large number, the useful active bacterium of damage bio-organic fertilizer; To add general interpolation of bacterium be vinelandii, photosynthetic bacterium, stalk become thoroughly decomposed agent, crop growth regulator etc. to tradition in addition, like this use technology and environment for use all had higher requirements, be unfavorable for bio-organic fertilizer popularization, popularize.

Summary of the invention

The defective and the deficiency that exist among the preparation method at existing bio-organic fertilizer, the invention provides a kind of preparation method of novel bio-organic fertilizer, the effective solution of this method high temperature in dry link causes the loss of bio-organic fertilizer available nutrient, by adding functional useful active bacterium, have practicality and security simultaneously.This preparation method is simply effective simultaneously, and cost is low, is convenient to popularize.

The objective of the invention is to be achieved through the following technical solutions.

A kind of preparation method of novel bio-organic fertilizer, feces of livestock and poultry, liquid natural pond, natural pond slag in the methane-generating pit, animal skin tankage or other contain the food of protein ingredient, the medicine tankage carry out pre-treatment as starting material, carry out multiple fermentation then, dehydration, decomposition reactor system, after innoxious index detection is qualified, by metering, pulverize by required proportioning, screening, granulation, oven dry, drying course is twice drying of flyback type that designs voluntarily, be cooled fast to normal temps by the vibrations fluidized bed plant in the process, screening, the low temperature coating adds bacterium, through check, package metro-measuring, finished product warehouse-in then.

The preparation method of described a kind of novel bio-organic fertilizer is characterized in that, is twice drying, and this drying is the flyback type desiccating method.

The preparation method of described a kind of novel bio-organic fertilizer is characterized in that the low temperature coating adds bacterium, and effectively bacterium is gel-shaped (colloid) genus bacillus, subtilis or bacillus megaterium and partial amino-acid, meat albumen and Avrmectin.

Benefit of the present invention and effect are: improve utilization rate of fertilizer, fall residual detoxifcation, improve crops quality, improve the soil, strengthen the disease resistance of crop, improve crop yield.Easy to use, security is good, and soil, environment are had no side effect, and belongs to ecological environment-friendly type fertilizer, is easy in organic, green, non-polluted farm product planting base and promote the use of the commodity food planting base.

Embodiment

A kind of preparation method of novel bio-organic fertilizer, liquid natural pond, natural pond slag in feces of livestock and poultry, the methane-generating pit, animal skin tankage or other food, medicine tankage that contain protein ingredient are carried out pre-treatment of raw material, the fermentation of dewatering then, can add zymophyte during the fermentation, accelerate fermentation; By composting, become thoroughly decomposed.Press the difference of raw material, divide During High-Temperature Composting and common compost, During High-Temperature Composting is that the raw material that fibre content is higher carries out aerobic fermentation reactor system, produces a large amount of heats simultaneously, temperature height (50～60 ℃) in the heap, thereby become thoroughly decomposed thoroughly the organic carbon content height.Can kill pathogenic agent, worm's ovum and weed seed in the raw material in the thermophilic fermentation process.Common compost generally mixes more earth, and leavening temperature is low, and digest process is slow, and the composting time is long.The nutrient chemical constitution is changed, and carbon-nitrogen ratio reduces, and can be increased by the mineral nutrition composition that plant directly absorbs, and forms soil ulmin.The condition that compost maturity is good: one, moisture.Keeping suitable water content, is the most important condition that promotes microbial activities and compost fermentation.Generally be advisable with 60%～75% of composting material amount water retaining capacity.Two, ventilation.Keep in the heap suitable air being arranged, breeding of favourable aerobic beneficial organism bacterium and activity promote organism to decompose.More should note during During High-Temperature Composting piling up the degree of tightness appropriateness, in order to ventilation.Three, keep neutrality or slight alkalinity environment.Can add lime or calcareous soil in right amount, acidity is regulated in neutralization, promotes microbial reproduction and activity.Four, carbon-nitrogen ratio.Microorganism is 25: 1 to the carbon-nitrogen ratio of the normal Decomposition of organic matter.And the leguminous green manure carbon-nitrogen ratio is 15～25: 1, weeds are 25～45: 1, gramineous crop stem stalk is 60～100: 1.Therefore according to the kind of composting material, add an amount of nitrogenous material, to transfer.
