利用沼气废渣发酵生物有机肥

Study on Biological Organic Fertilizer by Firedamp Dissolved Residue

研究了以EM菌剂为发酵菌种、沼气消化液残渣配合农作物秸秆为基质的生物有机肥发酵工艺技术,经单因素试验和正交试验确定的原料配比为75％废糟+25％秸秆,发酵时间为9天,接种量为0.5％～1.0％,主要指标腐殖酸含量达38.4％。

This test is the study on procedure technique of fermentation biological organic fertilizer, based on the material of firedamp - dissolved residue and straw. After singlecomparison experiment and multiple comparison experiment, we determined the material proportion; 75% waste lees and 25% straw, the fermentation time is 9 days, inoculation quantity is 0. 5% -1.0% , main index of containment of humic acid is 38. 4% .
