Abstract: To ascertain the effect of applying bio-organic fertilizer for 4 consecutive years on tomato fruit and soil biological characteristics, physiological and biochemical methods and high-throughput sequencing technology were combined to analyze its regulation effect on tomato fruit quality, soil nutrient content and microbial community structure.The results showed that,with chemical fertilizer replaced by bioorganic fertilizer, the sugar acid ratio, content of Vc and lycopene of tomatoes were significantly increased by 11.1%, 7.2% and 12.4% respectively. Soil nutrient measurement exhibited that, the high-efficiency nitrogen-fixing bacteria contained in bioorganic fertilizer could meet the nitrogen demand of tomato growth, and soil available phosphorus, available potassium and organic matter content were significantly increased by 147.0%, 38.8% and 35.6% respectively. High-throughput sequencing showed that, application of bioorganic fertilizer for four consecutive years could improve the relative abundance of soil Streptomyces, Ureibacillus and Bacillus, among which the activation effect on B. asahii was most significant. In addition,Coverage and Simpson index of tomato-planted soil microbial treated by bioorganic fertilizer for four consecutive years were both higher than those treated by common chemical fertilizer, which indicated that the bioorganic fertilizer containing high-efficiency nitrogen-fixing bacteria could improve soil microbe coverage and dominance to some extent. Obviously, continuous application of bioorganic fertilizer is helpful to improve tomatoes fruit quality, soil fertility and soil micro-ecological environment.

Key words: Tomatoes quality, Bioorganic fertilizer, Soil nutrient, Microbe diversity, Soil improvement
