Embodiment 1

[0045] A biogas slurry paste fertilizer, which consists of the following components:

[0046] Biogas slurry 35kg Urea 8kg Diammonium phosphate 8kg

[0047] Potassium sulfate 10kg Ammonified lignite 32kg Biogas microbial agent 2kg

[0048]Indole acetic acid 0.1kg Ferrous ethylenediamine tetraacetate 0.7kg

[0049] Citric acid 0.7kg Carboxymethylcellulose sodium 0.5kg Bentonite 3kg

[0050] Polyglycerin fatty acid ester 0.3kg.

[0051] A preparation method of biogas slurry paste fertilizer, the steps are as follows:

[0052] 1) Take weathered lignite and add ammonium bicarbonate in a ratio of 14.7%, make it ammoniate in a reaction kettle at a temperature of 20-30° C. for 24 hours to obtain ammoniated lignite;

[0053] 2) Take the biogas slurry that has been anaerobically fermented for 50 to 60 days using chicken manure as raw material, filter out the biogas residue through a filter press, take the liquid, add carboxymethyl cellulose sodium to the above liquid, and stir evenl...

Embodiment 2

[0076] Biogas slurry paste fertilizer as described in embodiment 1, the difference is that,

[0077] Biogas slurry 30kg Urea 15kg Diammonium phosphate 10kg

Abstract

The invention discloses fermented liquid pasty fertilizer which relates to the technology of utilizing fermented liquid for producing pasty and organic compound fertilizer, in particular to a method mixing fermented liquid of livestock manure with humic acid raw materials to prepare the pasty fertilizer and the application of the method, belonging to the technical field of novel organic fertilizer and the cyclic utilization of the resource of agricultural wastes. The pasty fertilizer includes the main component of fermented liquid, and is additionally provided with carbamide, diammonium phosphate, lemery, aminated wood coal, thickening agent and other additives; and the carbamide, the diammonium phosphate, the emery, the aminated wood coal, the thickening agent and the other additives are added to and uniformly mixed and stirred with the fermented liquid, and the mixture is pulverized to form a pasty shape. The invention which utilizes the fermented liquid to prepare the pasty fertilizer turns the wastes into resources, the preparation method is easy, and required equipment is simple, thereby the invention is easy to be easily popularized and applied to the fertilizer industry. The pasty fertilizer has the advantages of favorable dissolvability, full nutrition and obvious effect of yield and quality improvement and can be widely applied to vegetables, fruits, foodstuffs, forests and various cash crops.

Description

technical field [0001] The invention relates to a biogas slurry paste fertilizer and a preparation method thereof, in particular to a paste fertilizer prepared by mixing livestock and poultry manure biogas slurry and humic acid raw materials and a preparation method thereof, belonging to the technical field of new organic fertilizers and agricultural Waste resource recycling technology field. Background technique [0002] With the development of large-scale breeding industry, the country regards the development of large and medium-sized biogas projects as an effective measure to relieve energy pressure and reduce the disposal of livestock and poultry manure. According to statistics, by the end of 2007, my country has built 26.5 million households with biogas, 18,000 small biogas projects, with a total pool capacity of 700,000 cubic meters; 3 ) nearly 3,000, so my country's large and medium-sized biogas projects are in the development stage. As far as the current scale is e...
