Abstract
In this study, the effect of different fertilizers on the nutritional quality, sanitaryquality and the yield of greenhouse cucumbers were analyzed by comparative experimentswith chemical fertilizer and anaerobic fermentation residues (biogas fertilizer). Particularlythe properties of bio-fertilizer and diseases and pests inhibition of biogas fertilizer weredemonstrated and its comprehensive benefits were evaluated. The results show that comparedwith chemical fertilizer, biogas fertilizer increased the dry matter, solids, reductive sugar, Vc,soluble protein of cucumbers by 4.62%, 4.08%, 29.05%, 20.83%, 10.85% respectively; thechlorophyll of leaf was 9.18% higher and the incidence of aphids and mildew 20% and 25%lower respectively. After calculation, the yield was raised by 1323.4 kg/mu, an increase of15.90%. The income was increased by 22839.8 Yuan/mu and the output/input ratio reached63.75:1, which is 3.77 times than that of chemical fertilization. Results indicated that biogasfertilizer can effectively reduce diseases and pests, bring good economic, social, andenvironmental benefits, and promote the low-carbon circular development of crop farming.Keywords: anaerobic fermentation residues, ecology, cucumber
