Abstract

The present invention relates to a preparation method for biological organic fertilizers. The present invention is characterized in that mushroom residue and traditional Chinese medicine residue are firstly pulverized, and then, pass through a 15 to 40 mesh screen. Then, afer being uniformly mixed according to the proportion of poultry and livestock feces to the mushroom residue to the traditional Chinese medicine residue to mixed microorganism strains to mixed inorganic fertilizers to adhesive agents of (25 to 35): (25 to 35): (25 to 35): (2 to 3): (5 to 8): (1 to 2), the poultry and livestock feces, the mushroom residue, the traditional Chinese medicine residue, the mixed microorganism strains, the mixed inorganic fertilizers and the adhesive agents are added with right amount of water until the water content of the materials is from 20 to 40%. The materials are placed in a fermentation tank for being fermented for 5 to 15 days at a normal temperature, and the temperature in the fermentation tank is controlled to 40 to 70 DEG C in the process of fermentation. Simultaneously, proper aeration and stirring are carried out, and then, the processed materials are taken out from the fermentation tank for being predried and granulated. Then, the drying of the materials is carried out, and the biological organic fertilizers are prepared. The present invention has the advantages that leftovers of processing industries of agricultural and sideline products are sufficiently used, resources are rich, preparation is simple, and economic and social benefits are remarkable.

Description

Utilize feces of livestock and poultry to produce the method for biological organic fertilizer

Technical field:

The invention discloses a kind of manufacture method of bio-organic fertilizer, particularly utilize feces of livestock and poultry, mushroom residue, Chinese medicine slag method for the raw material production biological organic fertilizer.

Background technology:

The fertilizer that is adopted in the current agriculture production mainly contains two kinds: a kind of is inorganic fertilizer, also claim chemical fertilizer such as urea, phosphate fertilizer, potash fertilizer etc., another kind is fertilizer such as farmyard manure, feces of livestock and poultry etc., facts have proved that these two kinds of fertilizer in use all have advantage separately, shortcoming is separately also arranged: inorganic fertilizer is easy to use, fertilizer efficiency is very fast, control easily, short run effect is relatively good, but life-time service inorganic fertilizer, soil acidity is increased, the organic minimizing, soil compaction, soil fertility descends more, and people are just strong more to the dependency of inorganic fertilizer as a result, so form vicious cycle, dropped to astonishing degree from the whole country soil quality at present, and used inorganic fertilizer and can make the nitrate of greengrocery crop and nitrite content substantially exceed the standard that allows intake (AOI) 432mg/kg day of the World Health Organization and Food and Argriculture OrganizationFAO (WHO/FAO1973) regulation, therefore country has begun to pay attention to and has strengthened management and control to chemical fertilizer at present; Fertilizer does not pollute the soil, to improving crop quality good effect is arranged also, but use inconvenient, fertilizer efficiency is more slow, and can't accurately control, there is not treated feces of livestock and poultry simultaneously, its sulphur, substances content such as ammonia are very high, stink to high heaven, can pollute very big scope along with air-flow flows special summer, also can multiply sanitary insect pest, in order to address these problems, begun to have released some bio-organic fertilizers in the market, the advantage of inorganic fertilizer and fertilizer is combined effectively, this fertilizer mainly all is to utilize the tankage of various farm and sideline product processing industries to come out for raw material production, China is vast in territory, the tankage of farm and sideline product processing industry are of a great variety, and therefore prescription and the technology of utilizing these tankage to produce bio-organic fertilizer also has very big difference.

Summary of the invention:

The purpose of this invention is to provide a kind of prescription and method of utilizing feces of livestock and poultry, mushroom residue, Chinese medicine slag for the main material production bio-organic fertilizer.

The object of the present invention is achieved like this: at first respectively mushroom residue, Chinese medicine slag is pulverized the back and is crossed 15～40 purposes sieve, again feces of livestock and poultry, mushroom residue, Chinese medicine slag, microbial strains, inorganic fertilizer, tackiness agent is by 25～35: 25～35: 25～35: 2～3: 5～8: 1～2 mixed is even, microbial strains described here is meant common compound vinelandii, phosphorus bacteria, the potassium bacterium, probiotic bacterium, fiber bacterium etc., inorganic fertilizer is a urea, phosphate fertilizer and potash fertilizer, needs according to Different Crop, its ratio is 30～80: 0～40: 0～30, after these raw materials are mixed, adding an amount of water to water content is 20～40%, inserting fermentation vat fermented 5～15 days at normal temperatures, temperature in the fermenting process control fermentation vat is at 40～70 ℃, inflate 1～3 time by the material of aeration tube in fermentation vat of fermentation unit every day, each 0.5～2.0 hour, the stirring system that starts fermentation unit simultaneously stirs material, make the abundant aeration of material, carry out prebake through material being taken out from fermentation vat after the above-mentioned processing, granulation, dry again.

The present invention is owing to adopt feces of livestock and poultry, mushroom residue and Chinese medicine slag as main raw material, therefore raw materials cost is lower, abundant at the southern resources of production, simultaneously because mushroom residue itself has had abundant microbial bacteria, therefore lower to the microbial strains requirement of adding, the viable bacteria content of fertilizer finished product is also than higher.

Embodiment:

At first respectively mushroom residue, Chinese medicine slag is pulverized the back and is crossed 30 purpose screen clothes, urea, phosphate fertilizer and potash fertilizer prepare the mixing inorganic fertilizer in 20%: 40%: 40% ratio, feces of livestock and poultry, mushroom residue, Chinese medicine slag, mixing microorganisms bacterial manure, mix inorganic fertilizer, tackiness agent was by 30: 30: 30: 3: 6: 1 mixed is even, adding an amount of moisture content to water content again is about 30%, inserting fermentation vat fermented under normal pressure 8 days, leavening temperature is controlled at about 60 ℃, inflate 1 time by the material of aeration tube in fermentation vat of fermentation unit preceding 3 day every day in the fermenting process, time is about 0.5 hour, the stirring system that starts fermentation unit simultaneously stirs material, make the abundant aeration of material, inflate 3 time by the material of aerating system in fermentation vat of fermentation unit every day after the 4th day, each about 1 hour, the stirring system that starts fermentation unit simultaneously stirs material, make the abundant aeration of material, carry out prebake through material being taken out from fermentation vat after the above-mentioned processing, granulation, again the oven dry universal biological organic fertilizer.

According to the needs of Different Crop, the content of the ratio of the nitrogen of mixing inorganic fertilizer, phosphorus, potassium and feces of livestock and poultry is made the biological organic fertilizer of various special uses in can also filling a prescription by adjustment.
