Embodiment 1

[0015] A kind of method utilizing pig manure to manufacture organic fertilizer, comprises the steps:

[0016] (1) Cultivate seed flies: first select wild houseflies to cultivate seed flies, carry out fly egg production after breeding for 3 generations, collect fly eggs 18 days after seed fly eclosion for subsequent use; adopt water-containing 70% wheat bran during fly egg production As the egg-grabbing material, drop 7% ammonium carbonate solution on the egg-grabbing material at the same time;

[0017] (2) Fly egg inoculation: lay fresh pig manure on the processing device of the treatment field for fly egg inoculation, the thickness of the pig manure laying is controlled below 5cm, and the inoculation density is 1.5m2 for eggs produced by every 14,000 kinds of flies. ; The processing device is a deep cement pool at 16cm or a plastic basin placed on a shelf;

[0018] (3) Fly maggot cultivation: After the fly ovum was hatched, the room temperature was cultivated at 16°C for 5 d...

Embodiment 2

[0022] A kind of method utilizing pig manure to manufacture organic fertilizer, comprises the steps:

[0023] (1) Cultivate seed flies: first select wild houseflies to cultivate seed flies, carry out fly egg production after breeding for 4 generations, collect fly eggs 24 days after seed fly eclosion for subsequent use; adopt water-containing 74% wheat bran during fly egg production As the egg-grabbing material, drop 9% ammonium carbonate solution on the egg-grabbing material at the same time;

[0024] (2) Fly egg inoculation: lay fresh pig manure on the processing device of the treatment field for fly egg inoculation, the thickness of the pig manure laying is controlled below 5cm, and the inoculation density is 1.8m2 for the eggs produced by every 16,000 kinds of flies. ; The processing device is a deep cement pool at 18cm or a plastic basin placed on a shelf;

[0025] (3) Fly maggot cultivation: After the fly eggs were hatched, the room temperature was cultivated at 25°C fo...

Embodiment 3

[0029] A kind of method utilizing pig manure to manufacture organic fertilizer, comprises the steps:

[0030] (1) Cultivate seed flies: first select wild houseflies to cultivate seed flies, carry out fly egg production after breeding for 3 generations, collect fly eggs 22 days after seed fly eclosion for subsequent use; adopt water-containing 72% wheat bran during fly egg production As the egg-grabbing material, drop 8% ammonium carbonate solution on the egg-grabbing material at the same time;

[0031] (2) Fly egg inoculation: lay fresh pig manure on the processing device of the treatment field for fly egg inoculation, the thickness of the pig manure laying is controlled below 5cm, and the inoculation density is 1.7m2 for eggs produced by every 15,000 kinds of flies. ; The processing device is a deep cement pool at 17cm or a plastic basin placed on a shelf;

[0032] (3) Fly maggot cultivation: after the hatching of the fly eggs, the room temperature was cultivated at 20° C. f...

Abstract

The invention discloses a method for manufacturing an organic fertilizer by utilizing pig manure. The method comprises the following steps: (1) culturing breeding flies; (2) inoculating fly eggs; (3)culturing fly maggots; (4) screening out the fly maggots; and (5) preparing a finished product. According to the method disclosed by the invention, the curing speed of the pig manure is accelerated byutilizing activity of the housefly larvae, and nutrients in the pig manure is recycled in a form of fly maggot protein, so that loss of the nutrients is prevented, and caused harm of environment pollution and mosquito and fly breeding are effectively prevented. Biopotency of a food chain is improved, a pollution-free biological fertilizer and fly maggot protein feed are provided for agriculture development by comprehensively utilizing biological resources, and the method has good social benefits, economic benefits and environmental benefits, is suitable for intensive pig farms and is also suitable for small-sized raising farmers.

Description

technical field [0001] The invention relates to a method for making organic fertilizer by using pig manure. Background technique [0002] Pig manure is a by-product of the pig breeding industry. With the continuous expansion of the number and scale of intensive farms, the problem of pig excreta polluting the environment is becoming more and more serious. Most of the existing pig farms in my country do not have pig manure treatment facilities, and the treatment technology is relatively backward. Traditional methods are commonly used in rural areas to naturally ferment pig manure piles and rettings into manure for use, or use them in biogas digesters for anaerobic fermentation to obtain biogas. Among the above methods, the former takes a long time to ferment and usually takes about 30 days to ripen. The odor generated during the fermentation not only pollutes the environment, but also causes the loss of nutrients in the pig manure. The piled pig manure is also a breeding grou...
