Circular agriculture is an inevitable trend in the sustainable development of global agriculture. At present, there are issues such as insufficient utilization resources, serious land pollution, and lack technical support circular agricultural ecological parks. This study explores safe application organic fertilizer to field crops within A peanut (Arachis hypogaea L.)–wheat (Triticum aestivum L.)–maize (Zea mays L.) crop rotation system was selected research methods biogas residues on peanut–wheat–maize system. In this experiment, we set up different amounts base fertilizers, with no only chemical treatments serving controls. We determined yield, quality, heavy metal content, nutrient uptake wheat, maize, peanuts, well soil content under residue rates. The results experiment follows: (1) Biogas a increased yield maize. highest for each occurred when amount 67,500 kg hm−2, increases 36.7%, 26.6%, 14.1% respectively, compared treatment. (2) improved seed quality B3 treatment showed strong improvement potential, increasing crude protein by 3.92–7.48%, soluble sugar 36.99–49.70%, fat 0.95–3.27%, wheat 2.22–8.72%, 6.21–8.51%, maize 2.87–3.61%, 21.62–28.05% control. (3) enhanced nutrients contents effective soil. (4) did not cause excessive accumulation metals conclusion, positively impacts growth, health parks, has potential production systems. Future should focus determining optimal ratio their efficient use, mechanisms which can increase improve quality.
