Method for preparing special fertilizer for maize by utilizing pig manure

Abstract

The invention mainly relates to the technical field of pig manure harmless treatment and fertilizer preparation, and discloses a method for preparing a special fertilizer for maize by utilizing pig manure. The method comprises the following steps: cleaning pig manure, collecting pig manure, carrying out fermenting and carrying out packaging. The method is simple, automatic fermentation can be realized, the pig manure does not need to be added back after being taken out, manpower and material resources are saved, direct contact of unfermented malodorous pig manure by breeding personnel is avoided, the working environment is improved, good health is ensured, and the novel pig manure treatment method is provided. The floor of a pig house is arranged with a hollow structure, the mesh holes arethin and long, so that pig feet are prevented from falling into accumulated pig manure in the pig house, and the pig house is kept dry and sanitary; an EM bacterium solution is splashed before the pig manure in the pig house is washed out, and the EM bacteria are mixed with the pig manure after the washing, so that artificial stirring is avoided; a pig manure temporary storage chamber below the pig house has a certain depth, so that the pig manure after washing can be subjected to initial fermentation in the pig manure temporary storage chamber; bad smell is removed; breeding of the insects is prevented; the environment of the pig house is improved; and the pathogenic bacterial infection of live pigs is reduced.

Description

technical field [0001] The invention mainly relates to the technical field of pig manure harmless treatment and fertilizer preparation, in particular to a method for preparing special corn fertilizer by using pig manure. Background technique [0002] With the gradual increase of pig farmers, the amount of pig manure is also increasing, and in the current breeding process, pig manure is randomly piled up, causing a bad smell and causing great pollution to the air, water and land environment. It will cause great harm to human health, so people pay more and more attention to the treatment of pig manure. The existing patent document CN 101671203 A discloses a simple method for producing high-efficiency bio-organic compound fertilizer by using pig manure. CN 104003776 A Disclosed is a kind of harmless treatment of pig manure and chicken manure mixed manure to make organic fertilizer. CN 101279861 A discloses a method for processing pig manure to produce organic fertilizer. CN 103...

[0002] With the gradual increase of pig farmers, the amount of pig manure is also increasing, and in the current breeding process, pig manure is randomly piled up, causing a bad smell and causing great pollution to the air, water and land environment. It will cause great harm to human health, so people pay more and more attention to the treatment of pig manure. The existing patent document CN 101671203 A discloses a simple method for producing high-efficiency bio-organic compound fertilizer by using pig manure. CN 104003776 A Disclosed is a kind of harmless treatment of pig manure and chicken manure mixed manure to make organic fertilizer. CN 101279861 A discloses a method for processing pig manure to produce organic fertilizer. CN 103708967 A discloses a method for using pig manure to produce organic fertilizer. The processing methods of the above four kinds of pig manure are to prepare pig manure into organic fertilizer, but in the process of preparation, it is necessary to take out the pig manure first, mix it, and then put it in the fermentation tank for fermentation, and it needs to carry out multiple transfers and treatments in the middle , pig manure is dirty and smelly, seriously deteriorating the working environment of workers
