Abstract: The effects of biogas residues on the outputs, production value and qualities of the apple were studied in the field. The results indicated that biogas residues can not only enhance the apple yield and improve fruit nutrition quality, but also reduce agricultural chemicals and chemical fertilizer disbursement and improve the environment quality. Under the condition (biogas residues: chemical fertilize)1:1,the qualities of apple was best, It showed that in using biogas residues in household biogas digester the total output of apple was 6.61% higher than that in using chemical fertilize, each hectare additionally receives 7626 Yuan. The reductive sugar、the vitamin C and sugar of the apple were respectively 5.9%、67.6% and 16.0% higher than that in using chemical fertilize; that in using biogas residues in project biogas digester the total output of apple was 6.80% higher than that in using chemical fertilize, each hectare additionally receives 6268.5 Yuan. The reductive sugar、the vitamin C and sugar of the apple were respectively 1.5%、3.1% and 2.2% higher than that in using chemical fertilize; that in using biogas residues in project biogas digester the quality of apple was different with that in using biogas residues in household biogas digester.
