Embodiment 1

[0022] The preparation method of utilizing dead livestock and poultry of the present embodiment to produce high organic nitrogen liquid organic fertilizer comprises the following steps:

[0023] (1) Freeze and temporarily store the collected carcasses of sick and dead poultry and animal slaughtering leftovers, and crush them after reaching a certain amount (500kg) or more to obtain 3-5cm square debris;

[0024] (2) Put the debris into the alkali-resistant reaction kettle, and then add a potassium hydroxide solution with a concentration of 1.1.0mol / L according to the mass of the solid-liquid ratio of 1:5, and control the total volume of the charge to account for the effective volume of the alkali-resistant reaction kettle Then turn on the switch of the alkali-resistant reactor to heat up to 100°C, and stir slowly at 100°C under normal pressure (stirring rate is 2 to 3 revolutions / min) for 2 hours. Under this condition, the debris in the The meat, fat, hair, horns, hooves, etc. ...

Embodiment 2

[0028] The preparation method of utilizing dead livestock and poultry of the present embodiment to produce high organic nitrogen liquid organic fertilizer comprises the following steps:

[0029] (1) Freeze and temporarily store the collected carcasses of sick and dead poultry and animal slaughtering leftovers, and crush them after reaching a certain amount (500kg) or more to obtain 3-5cm square debris;

[0030] (2) Put the debris into the alkali-resistant reaction kettle, and then add a potassium hydroxide solution with a concentration of 1.5mol / L according to the mass of the solid-liquid ratio of 1:3, and control the total volume of the charge to account for the effective volume of the alkali-resistant reaction kettle. 70% or so; then turn on the switch of the alkali-resistant reactor to heat up to 100°C, and stir at a slow speed (stirring rate of 2 to 3 revolutions / min) at 100°C and normal pressure for 1.5h. The meat, fat, hair, horns, hooves, etc. are completely liquefied a...

Embodiment 3

[0034] The preparation method of utilizing dead livestock and poultry of the present embodiment to produce high organic nitrogen liquid organic fertilizer comprises the following steps:

[0035] (1) Freeze and temporarily store the collected carcasses of sick and dead poultry and animal slaughtering leftovers, and crush them after reaching a certain amount (500kg) or more to obtain 3-5cm square debris;

[0036] (2) Put the debris into the alkali-resistant reaction kettle, and then add a potassium hydroxide solution with a concentration of 1.5mol / L according to the mass ratio of solid-liquid ratio of 1:2, and control the total volume of the charge to account for the effective volume of the alkali-resistant reaction kettle Then turn on the switch of the alkali-resistant reactor to heat up to 100°C, and stir slowly at 100°C under normal pressure (stirring rate is 2 to 3 revolutions / min) for 2.0h. Under this condition, the debris The meat, fat, hair, horns, hooves, etc. in the liq...

Abstract

The invention belongs to the technical field of agricultural fertilizers, and particularly relates to a preparation method for producing a high-organic-nitrogen liquid organic fertilizer by utilizing livestock and poultry died of diseases. The preparation method for producing the high-organic-nitrogen liquid organic fertilizer by using the livestock and poultry died of diseases comprises the following steps: carrying out alkaline hydrolysis and solid-liquid separation on crushed animal materials by using alkaline liquor to obtain a mixed solution with an upper layer being a grease layer and a lower layer being a colloidal mother solution, and separating grease to obtain the colloidal mother solution; and mixing humic acid with the colloidal mother solution, and then adjusting the pH value of the system to 5.5-8.5, thereby obtaining the fertilizer. By adding the macromolecular substance humic acid to adjust the pH value, on one hand, organic matters in the organic fertilizer are increased, and on the other hand, the supporting effect of the humic acid is exerted to prevent precipitation and flocculation of organic nitrogen, so that the content of the organic nitrogen is increased. The liquid organic fertilizer prepared by the preparation method disclosed by the invention has the advantages of high organic nitrogen utilization efficiency, high organic matter content and high potassium content, and can meet the requirements of the whole crop growth period on the nitrogen element.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a preparation method for producing high-organic nitrogen liquid organic fertilizers by utilizing sick and dead livestock and poultry. Background technique [0002] With the development of the breeding industry and the meat industry, the number of animal slaughtering waste and dead livestock and poultry carcasses is also increasing, and the pressure of handling has become very heavy. For dead livestock and poultry carcasses, if not handled properly, it will not only cause serious animal epidemics, but also cause serious environmental pollution. The utilization rate of leftovers from slaughtering of animals is low, resulting in waste of resources. Therefore, how to rationally utilize the leftovers from animal slaughtering and dead livestock and poultry corpses has also become one of the problems urgently needed to be solved at present. [0003] The tr...
