Abstract: With randomized block design, a field experiment was conducted in greenhouse to study the effects of combined application of biogas residues and chemical fertilizers on the tomato growth and its fruit yield and quality. The combined application of biogas residues and chemical fertilizers benefited the tomato growth and its fruit yield and quality. The yield of  the combined application of 60% biogas residues and 40% chemical fertilizers were higher than the other treatments. The fruit quality under the application of 60% biogas residue and 40% chemical fertilizers also improved significantly, with the Vc content (91.09 mg·kg^-1) and total sugar content being 21.32 mg·kg^-1and 2.13% higher than the control, respectively. Among the test fertilization combinations, 60% biogas residue combined with 40% chemical fertilizers was the best one for greenhouse tomato’s growth and its fruit yield and quality.
