Abstract
The invention discloses an efficient, fast and fractional fermentation method of the organic fertilizer. The method comprises the following steps: firstly screening raw materials such as excrement and stalk, removing impurities, grinding for standby, wherein the water contents of excrement and stalk are adjusted to 65-70wt% and the raw materials per ton comprises 80-85% of animal waste and 15-20% of stalk; stirring the raw materials evenly to convey to a solar greenhouse fermentation plant, performing sterilization and fermentation, wherein the fermentation temperature is controlled to 55-65 DEG C and the fermentation time is controlled to 48-72 hours; when the decomposed fertilizer is tested to be qualified, adding 2-3 kilometers of the biological agent--Bacillus laterosporus per ton of the fertilizer, stirring evenly for fermentation, wherein the temperature is controlled to 30-45 DEG C, the fermentation time of beneficial bacterium is controlled to 48-72 hours; and pelletizing the fermented raw materials, drying, polishing, screening, packaging quantitatively and warehousing the finished product. The fermentation method of the invention can be used in the continuous production of the organic fertilizer.
Description
Technical field
The present invention relates to a kind of production method of fertilizer, relate to a kind of microbial fermentation processes of fertilizer specifically.
Background technology
According to investigations, the most areas of China have been subjected to destruction in various degree because of long-term application chemical fertilizer has made ecological environment of soil, soil physical and chemical property and soil microflora, especially too much use simple substance chemical fertilizer, made nutritive element serious disproportion in the soil, the fertility supply capacity descends, the soil compaction aggravation, and the rhizosphere soil microorganism dominant population reduces in a large number, and to a certain extent quality of agricultural product has been caused pollution, make product be difficult to reach the requirement of green organic food.Along with the microorganism field progress of science and technology, the various countries scientist generally believes that fertilizer will develop to efficient, compound direction, promptly should seek a kind of new bio compound fertilizer that organic and inorganic and microbial fertilizer global advantage can be integrated in one.
In the north; industry area based on the husbandry breed; along with agricultural industry is constantly adjusted; aquaculture development is rapid; breeding production management state and development trend are good; formed mass-producing; overstocking of the waste of feces of livestock and poultry and fodder grass brought a difficult problem for breed factory and culture zone; a large amount of culture zone peripheries that are deposited in; become the breeding site, regeneration ground of worm fly through rotting for a long time, make the ambient air environmental degradation, phenomenon such as the smell is awful; also can cause the generation of the various eqpidemic diseases of livestock, have a strong impact on people's living environment and health.
In the past, in vast husbandry area, the treatment process that solves this Litter, rubbish and excrement of animals is that the nature stacking is converted into farm manure.This method is in the process of making, using and have a series of problems: the one, and content of microorganisms is less, helps the harmful microorganism growth and breeding; The 2nd, open-air long-time the stacking, particularly the nitrogen nutrient loss is more for nutrient; The 3rd, spontaneous fermentation is not subjected to the control of human factor, includes the deleterious sick worm of plant growth; The 4th, it is not thorough to become thoroughly decomposed, and consumption is big slightly, root will occur burning and burn seedling, causes the underproduction.It has stench, use inconvenience, be not suitable for mechanized operation, phenomenon such as inhomogeneous.
Fertilizer processing enterprise in the past carries out scale production, because of being subjected to seasonal restriction, for reaching the effect of becoming thoroughly decomposed, heats to adopting steam in the proving room, and energy consumption is big, because of a large amount of so of boiler emission
2Flue dust causes atmospheric pollution.My company cultures and a tame emphasis leading enterprise of deer product deep processing based on red deer, in order to develop new market, is starting point with the national policy recycling economy, the living environment of solution culture zone, improves the quality product of farm crop.
Summary of the invention
The objective of the invention is: a kind of efficient, fast and fractional fermentation method of organic fertilizer is provided.Be combined on the basis of traditional farm manure, underground heat, steam fermentation process, adopt fertilizer luminous energy quick fermentation manufacture craft to produce fertilizer, nutrient is complete, the energy chessom, increases fertility, and objectionable impurities is handled thoroughly, improves quality product.But suitability for industrialized production, stdn quality, be convenient to pollution-free green-efficient organic fertilizer of storing, transport, selling.This techniques save energy is pollution-free simultaneously.Solution makes the organic famine in soil because of soil life-time service chemical fertilizer, nutritive element serious disproportion in the soil, and the fertility supply capacity descends, the problem that soil compaction is serious; Solution is because of original fermentation process, cost height, boiler emission volume of smoke and SO
2Solve the problem that original farm manure can not mechanize be implemented; Improve fertilizer quality.
Technical scheme of the present invention is:
1. raw material is prepared and allotment
Earlier raw materials such as ight soil, stalk are screened, remove impurity and pulverize standby; , the water content of stalk and ight soil should be adjusted to weight percent 65%--70%; Raw material per ton is thrown in ratio: weight percent excrement of animals 80%---85%, stalk 15%---20%;
2, sterilization fermentation
Raw material stirring evenly back is carried out sterilization fermentation with being transported to the solar energy greenhouse fermentation plant, and leavening temperature is controlled at 55-65 ℃, fermentation time 48--72 hour;
3, probiotics fermentation
To become thoroughly decomposed good fertilizer after the assay was approved, add bacteria agent one bacillus laterosporus 2-3 kg/ton, and stir, controlled temperature is at 30-45 ℃, probiotics fermentation time 48-72 hour;
4, back arrangement
Raw material input granulation workshop by fermentation is processed into particle, dry control moisture weight percent≤20%, through polishing, screening, metering packing, and the finished product warehouse-in.
Advantage of the present invention is:
1, reduces the smoke contamination that uses boiler to cause, save energy, the characteristics that cost is low.
2, fertilizer can provide full nutrition, and fertilizer efficiency is long, can increase and upgrade the soil organism, promotes microbial reproduction, improves the physico-chemical property and the biological activity of soil, is the main nutrient source of pollution-free food production.
3, yeast phase is short, does not limit season limit, meets large-scale production.
4, become thoroughly decomposed thoroughly and contain a large amount of probioticss.
5, improve geology, have heat retaining property and drought resistance.
6, can improve the quality of products.Can make base manure and topdress.
Through≤1000 of per 100 grams of fertilizer nitrogen+phosphorus+potassium content 〉=12%, organic content 46%, the induced worm egg death rate 〉=95% coliform value of this explained hereafter.Living bacteria count (cfu) hundred million/g 〉=0.20.
