Zusammenfassung:	The invention discloses an accumulation and application method for biogas residues, and belongs to the technical field of agricultural fertilizer increasing. The method comprises the following steps:firstly, residues/residual liquid after fermentation in a methane tank are/is placed in a secondary fermentation furnace for secondary fermentation; secondly, cellulolytic enzyme is added to the secondary fermentation furnace to limit the temperature and pressure for re-decomposition; thirdly, anaerobic fermentation is performed in the secondary fermentation furnace, and heating and stirring are performed for auxiliary fermentation; fourthly, biogas slurry is obtained by filtering for pipe accumulation irrigation, and a used pipe is a liquid accumulation shunt pipe; fifthly, residues from theliquid accumulation shunt pipe and the secondary fermentation furnace are removed. Biogas or biogas slurry is further fermented for water adding irrigation, and accordingly, uneven topdressing or excessive fertilizer accumulat
