Abstract：A trial was conducted to explore the effects of different application amounts of cow dung,earthworm manure,and taille soil fertilization treatment on soil improvement in facility tomato,Additionally,the optimal application of organic fertilizer and biofungus fertilizer was investigated for the best grown results.Soil physical and chemical properties,soil enzyme activity,and tomato quality were used as evaluation indicators to compare different amounts of organic fertilizer,including a mixture of biofungus fertilizer and appropriate organic fertilizer as well as CK(no fertilizer).Based on the analysis of soil nutrient characteristics and tomato quality of each treatment fertilizer,the optimal fertilization treatment was selected.The results showed that different fertilization treatments significantly improved soil nutrients and fruit quality.After the application of organic fertilizer,the best effect of tomato quality and soil improvement mainly focused on the medium or high amount,with the best improvement effect of cow dung.Further optimization was carried out by com-bining the optimal amount of cow dung and biofungal fertilizers(Bacillus subtilis,Bacillus hartsimmermontii,Bacillus amyloliquefaciens).The results showed that Bacillus hartsimmermontii had the strongest ability to dissolve the cow dung,significantly increasing soil nutrients.The combination of Bacterium hartsimmermontii and medium amount cow dung significantly improved soil nutrient and notably enhanced the quality of facility tomato.Correlation analysis indicated that the combination of different amount of organic fertilizers and biofertilizers showed a significant hand high significant cor-relation with soil nutrients and tomato quality.
