Abstract：In order to investigate the synergistic of different bio-organic fertilizers combined with mineral fertilizers on tomato production under different planting patterns,a greenhouse field experiment was conducted to compare the effects of different bio-organic fertilizers combined with mineral fertilizers on tomato growth,quality,yield,and soil fertility under different planting patterns.The results showed that compared with CK,T4(240 cm ridge spacing,vermicompost organic fertilizer combined with mineral fertilizer)increased the content of total phosphorus,available potassium and organic matter in soil,while decreased the soil pH and the content of heavy metals cadmium,chromium,nickel and lead.Compared with conventional planting(CK)and other treatments,the stomatal conductance and leaf transpiration rate of T4 tomato leaves were significantly increased.The net photosynthetic rate and intercellular CO2 concentration of leaves were significantly higher than those of CK,T1,T2 and T3,but there was no significant difference compared with T5 and T6.The quality and yield of tomato have both improved,with a significant increase in total sugar content,soluble solids contentand sugar-acid ratio.There was no significant difference in vitamin C content between T4 and T2,but it was signif-icantly higher than other treatments.Based on comprehensive anlysis,T4(240 cm ridge spacing,vermicompost organic fertilizer combined with mineral fertilizer)is the best fertilizer treatment to achieve increased yield and quality,as well as improved soil quality of greenhouse tomato.
