Abstract

The invention relates to a method for preparing bio-organic fertilizer from biogas residues. The organic fertilizer is prepared from the following raw materials in parts by weight: 80-160 parts of thebiogas residues, 15-40 parts of rice bran, 20-30 parts of silkworm excrement, 45-65 parts of sludge, 8-18 parts of urea, 8-18 parts of bagasse, 10-16 parts of waste molasses, 10-18 parts of waste tealeaves, 10-12 parts of peanut stalk root powder, 0.05-0.5 part of microbial agents and the like. The method comprises the following steps: raw material proportioning, strip stacking, adding of the microbial agents, stirring fermentation and separating screen processing. The bio-organic fertilizer prepared with the method has the characteristics that the content of bio-organic matter is high, soil is improved, soil hardening is prevented, harmful bacteria in the soil can be effectively inhibited, growth of crops can be promoted effectively and rapidly and the like.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizer, in particular to a method for making bio-organic fertilizer by using biogas residue. Background technique [0002] The utilization rate of chemical fertilizers in my country is not high, and the utilization rate of nitrogen fertilizer in the current season is only 35%. According to data from the Food and Agriculture Organization of the United Nations, from 1980 to 2002, China's chemical fertilizer consumption increased by 61%, while grain output only increased by 31%. Low fertilizer use efficiency has always been a problem in China's agricultural fertilization. The disadvantages of long-term application of chemical fertilizers are: (1) increased heavy metals and toxic elements; (2) reduced microbial activity, difficult to transform and degrade substances; (3) nutrient imbalance, nitrate accumulation; (4) intensified acidification, The pH changes too much. [0003] The total amou...
