Embodiment Construction

[0012] A biogas residue organic and inorganic formula fertilizer, including urea, monoammonium phosphate, potassium sulfate and biogas residue are evenly mixed and granulated; the weight ratio of the urea is 30%, and the weight ratio of the monoammonium phosphate is 12% , the weight ratio of potassium sulfate is 20%, and the biogas residue is 38%; the organic matter content in the biogas residue organic-inorganic formula fertilizer is more than or equal to 30%.

[0013] Configuration process:

[0014] Mix 300Kg of urea + 120Kg of monoammonium phosphate + 200Kg of potassium sulfate + 380Kg of biogas residue evenly, and granulate to produce the present invention.

[0015] In the finished product of the present invention after making: content index is N+P 2 o 5 +K 2 O≥30%, preferably, N≥15%, P 2 o 5 ≥5%, K 2 O ≥ 10%. Organic matter ≥ 20%.

[0016] Biogas fertilizer is the residue after anaerobic fermentation, including liquid residue, which is biogas slurry, and solid res...

Abstract

The invention discloses an organic and inorganic formula fertilizer of biogas residue. The organic and inorganic formula fertilizer of the biogas residue is prepared by uniformly mixing and pelleting the following materials by weight percent: 30% of urea, 12% of monoammonium phosphate, 20% of potassium sulphate and 38% of biogas residue, wherein the content of organic matters in the organic and inorganic formula fertilizer of biogas residue is greater than or equal to 30%. The organic and inorganic formula fertilizer of the biogas residue is practical, low in production cost, convenient to use, good in fast-acting property and long in duration. The fertilizer efficiency is remarkably improved, biogas residue is utilized well and changed into wealth, high-quality fertilizer is provided for pollution-free agricultural production, and the taste and quality of crops can be effectively improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a biogas residue organic and inorganic formula fertilizer. Background technique [0002] At present, people generally use urea or other compounds as fertilizer in the planting process, and urea as fertilizer also has certain deficiencies and defects. [0003] Ordinary urea only has the basic function of nitrogen element, which is a quick-acting fertilizer with short duration and low fertilizer efficiency. At the same time, the utilization rate of urea is about 30%-40%, which has not been fully utilized. [0004] Some biogas slurry in daily life is generally used as fertilizer or treated as garbage, and the biogas slurry has not been used reasonably. [0005] After processing the biogas slurry, biogas residues will remain, and the biogas residues can be directly used as fertilizer, and the effect is not obvious. At the same time, due to its high moisture content, it is not commonly used at prese...
