Description

A kind of Ecological Disposal pig manure manufactures the method for organic fertilizer

Technical field

The invention belongs to biotechnology, relate to organic fertilizer, furthermore, it is understood that relate to the fertilizer being made up of animal wastes.

Background technology

Pig manure is the accessory substance of pork pig animal husbandry, and with the continuous expansion of intensive culture number and scale, the problem mesh benefit of the excreta environmental pollution of pig is serious.China's existing pig farm major part does not has the treatment facility of Pig dung and urine, and treatment technology is also relatively backward.In rural area conventional traditional method by pig manure heap, macerate spontaneous fermentation and become barnyard manure and use, or it is carried out in methane-generating pit anaerobic fermentation prepare biogas and use.In said method, the former fermentation time is long, typically require and could cure for about 30 days, the foul smell producing during fermentation not only pollutes environment, also result in the loss of pig manure Middle nutrition composition, the pig manure stacked or the multiplying of mosquitos and flies, breeding spot, and mosquitos and flies spreads disease, and is degrading environment for human survival further；Although the latter make use of the energy being produced by biochemistry, decreasing pollution, but the nutritional labeling in pig manure failing to make full use of, biogas residue still has secondary pollution to environment, also expends substantial amounts of water simultaneously.In order to reduce the pollution of pig manure, the way that also someone uses high-temperature heating pig manure to be allowed to rapid aging processes pig manure, and this method still fails to make full use of the nutrient in pig manure.Many in recent years scientific research technical staff are in process and the application of concern Pig dung and urine.But up to now, use bioengineering that swine manure treatment becomes the technology of pollution free organic fertilizer be not yet seen in report and be known by people.

Content of the invention

It is an object of the invention to provide a kind of with biotechnology, use Ecological Disposal pig manure, the method making organic biofertilizer.

Biotechnology is one of focus in current emerging technology, the improvement of employing Ecological Disposal animal excrements, beneficially ecological environment and the exploitation of pig manure resource.Inventor is through research for many years and test, the method that the utilizing housefly larva to ecologically providing processes pig manure includes: (1) is first chosen wild housefly and carried out raising to cultivate kind of a fly, carrying out fly blow production after 3～4 generations of breeding, the fly blow collecting after it is sprouted wings 4～18 days is standby；(2) processing means that fresh pig manure is laid in Treatment stations carries out fly blow inoculation, and pig manure lay thickness is about 6cm, ovum inoculation 0.5～1m that inoculum density is produced by every 10,000 kind flies²；(3) carrying out fly maggot cultivation after, after fly blow hatching, room temperature is cultivated 3～5 days more than 16 DEG C, and fly maggot is drawn the nutrient in pig manure and grown up, and decomposes the composition producing foul smell in pig manure simultaneously, and its secretion has killed again the harmful bacterium of part；(4) hereafter with the stainless steel mesh of 18～20 mesh, fly maggot is sifted out；(5) pig manure sifting out uses and seals the way preserving 1 week, or heats the way of 15min under 80 DEG C of temperature conditionss, obtains non-harmful pig manure bio-feritlizer after killing remaining fly maggot and maggot pupa；(6) fly maggot sifting out can be directly used as feed, or dries prepared fly-maggot protein.

For ensureing that egg laying amount is raised and bred and increase to housefly, the condition planting fly fostering requirement is to make feed with milk powder and white sugar, cultivates the stainless steel cylinder mould of cage tool 20 mesh, and every day, light requirement was according to 8～12 hours, relative air humidity 60%～80%.

Fly blow uses the wheat bran of aqueous 60%～70% to connect ovum material when producing, and for stimulating female fly to lay eggs, can connect the sal volatile dripping 6% on ovum material.

Swine waste treatment device is the deep cement pit of 15cm, or the plastic tub placed on layer frame.

Inventor is through research, it is indicated that in fly maggot incubation, temperature is higher, cultivates required time shorter；Usual 16～20 DEG C of needs 5 days, 20～25 DEG C of needs 4 days, more than 25 DEG C only need 3 days.In order to prevent the degeneration of kind of fly, within a certain period of time, need to introduce new housefly in order to cultivate kind of a fly.

Using the method that the present invention provides, prepared pig manure biological fertilizer products is loosened, and in dark brown, odorless, water content 45%～50%, sampled analysis, this fertilizer contains: nitrogen 1.976 ± 0.184%, phosphorus 1.700 ± 0.189%, potassium 0.792 ± 0.205%；Available nitrogen 212.49 ± 57.25mg/100g, increases about 20% than the pig manure fertilizer of curing naturally；Ammoniacal nitrogen 89.00 ± 39.59mg/100g, frequently the pig manure fertilizer of curing naturally increases about 60%.Compared with the pig manure of stacking curing naturally, coliform group count and total number of bacteria all substantially reduce, sustainable about 1 month of antibacterial effect；Meanwhile, fly multiplies and significantly reduces, and can not normal development.The present invention utilizes common house-fly grub activity to accelerate the curing speed of pig manure, and the form with fly-maggot protein reclaims the nutrient in pig manure, the harm that the loss that effectively prevent nutrition speed and the environmental pollution causing and mosquitos and flies thereof are multiplied, not only increase the biopotency of food chain, living resources can also be comprehensively utilized, there is provided a kind of non-harmful bio-feritlizer and fly-maggot protein fodder for agricultural development, there is good social benefit, economic benefit and environmental benefit, it is applicable to Intensive Farm of Pig Raising, be also applied for small-sized raising family.

Embodiment is on the basis of 1 ton of pig manure.Take the some heads of local wild housefly, cultivate among the stainless steel cylinder mould that volume is 100 × 60 × 70cm, 20 mesh, it is ensured that its illumination reaches 10 hours, and relative air humidity is 60%～70%, raised by the aqueous solution of milk powder, white sugar, be used for laying eggs after cultivating for 3～4 generations；Planting after fly sprouts wings 3 days and starting to lay eggs in a large number, the wheat bran with aqueous 60%～70% is prepared in right amount and is connect ovum material, is contained in dark color and connects in ovum box, its thickness about 5cm, it is used for collecting the fly blow of after emergence the 4th～18 day, put in box during during every morning 9 or afternoon 5 and connect ovum material, after 24 hours, collect fly blow.The fly blow collected is standby.Being laid in fresh pig manure in the cement pit equipped with the Treatment stations of stainless steel screen window, the deep 15cm in pond, strict control pig manure thickness is at below 6cm.Inoculating in pig manure by standby fly blow, inoculum density is laid eggs by 10,000 kind flies and is inoculated 0.8m², cultivate 4 days under the conditions of room temperature 20 DEG C, allow fly blow hatching grow into larva, while larva draws pig manure nutrition, also just processed pig manure.After 3～5 days, make maggot excrement separate with the stainless steel mesh of 18 mesh, obtain the fresh maggot of 200kg, obtain 650kg bio-feritlizer simultaneously.Again the bio-feritlizer that obtains is sealed and preserves 1 week so that it is in can be used as Term Fertilization after remaining fly maggot and the death of fly pupa.
