Description
Technical field
The invention belongs to organic fertilizer preparing technical field, and in particular to a kind of biogas slurry organic fertilizer and preparation method thereof.
Background technology
It is the common waste treatment method in current vast rural area using methane-generating pit treatment animal wastes and plantation discarded object, should
Animal wastes and plantation discarded object can be not only converted into useful biogas by method, to meet home-use fire, illumination, hot water etc.
The demand of aspect, can be with output biogas residue and biogas slurry.Prior art is for the main methods of biogas slurry：By biogas residue by sending out
Solid organic fertilizer is made as after ferment and water removal.Biogas residue contains humic acid 10% ~ 20%, organic matter 30%-50%, full nitrogen 10%-2.0%,
Phosphorous 0.4%-0.6%, full potassium 0.6%-1.2%, are a kind of slow, fast fertilizer having both.Can improve oranges and tangerines sugariness using natural pond fertilizer
0.5 degree of -1.0 degree, increases production 10%-30%.
But also rested on for the utilization of biogas slurry for prior art and directly applied as Liquid organic fertilizer.But due to
Biogas slurry has strong stink and can not place for a long time, therefore, biogas slurry is very low as the utilization rate of Liquid organic fertilizer, more
Biogas slurry is discharged or as pouring clear water return field after being sent to sewage treatment plant's treatment, and the nutriment in biogas slurry is most of
It is wasted.
