Problems solved by technology

Most of the starters currently on the market are based on lactic acid bacteria, which can only be used for storage and fermentation, but cannot degrade a large amount of fibrous substances in feces, nor can they increase their protein content.
Therefore, in the prior art, there is a lack of molding technology for the production of organic compound fertilizer by fermenting livestock manure

Embodiment Construction

[0012] A method for producing organic compound fertilizer by fermenting livestock manure, the method includes material pretreatment, puffing, batching, fermentation and granulation, and is characterized in that the production process is:

[0013] (1) Material pretreatment: evenly smash livestock manure (cattle, horse, chicken, duck manure, etc.), and control the moisture content at 55% to 65%; the particle diameter is preferably 0.5 to 1cm;

[0014] (2) Expansion: the above-mentioned livestock manure is mixed with an expansion agent, and its consumption is 1.5-3.5% of the total amount of the above-mentioned livestock manure, and then put into the extruder, the temperature is controlled at 200 ° C, and the pressure is 10 kg / cm2, and the puffing treatment is carried out. Make feces pellets; crush and sieve the feces pellets with a pulverizer, and take puffed fine powder with a diameter of <1.0mm;

[0015] (3) Ingredients: the above-mentioned puffed fine powder is 40% to 55% by w...

Abstract

The invention provides a method for producing an organic compound fertilizer by fermenting animal manure. The method comprises the steps of material pretreating, swelling, blending, fermenting and granulating, wherein the content and the survival rate of beneficial active bacteria in the obtained organic compound fertilizer are high. By adopting the organic compound fertilizer, sufficient and balanced nutrition can be provided for crops, the pollution of chemical fertilizers and farm chemicals on farmlands and products can be gradually eliminated by means of the large fermenting and decomposing capacities of a flora, and the soil is improved and is up to the environmentally-friendly and organic standards; and a composition containing an active microorganism flora can play a role continually in the soil, so that the effects of increasing yield and improving quality are achieved.

Description

technical field [0001] The invention relates to a method for producing organic compound fertilizer by fermenting livestock dung, which belongs to the field of new biological energy utilization. Background technique [0002] Organic fertilizers have been used in agriculture for many years, especially in rural areas where there are a large number of animal and plant wastes, which can be accumulated, fermented, and applied on the spot. They have a wide range of sources, are economical and have a wide variety. In my country, plant stalks, human and livestock excrement and urine are generally used, or specially planted crops such as green manure are used, and river mud, bone meal, plant ash, etc. are also used. Organic fertilizers are different from chemical fertilizers. They contain compound elements, including not only nitrogen, phosphorus, and potassium, but also calcium, magnesium, and other trace elements needed by crops. The nutrients contained in organic fertilizers are mo...
