Salmonella is a common zoonotic pathogen. Pig manure biochar prepared at 300℃, 500℃ and 700℃ was applied to four typical vegetable soils: black, brown, red and brick-red soils, respectively, and the effect of biochar on the survival behavior of Salmonella in the soil was investigated using indoor thermoregulation experiments. The results showed that biochar significantly promoted the survival of Salmonella in black soil, red soil and latosol, but not in brown soil. The preparation temperature of biochar had different effects on the survival of Salmonella. The survival time of Salmonella in the soil with biochar at 300℃ was longer than that of at 500℃ and 700℃. The longest survival time of Salmonella was observed in Latosol with 300℃ biochar (111.36 day). Simple correlation analysis showed that soil pH, organic matter and total nitrogen content were significantly positively correlated with the survival time of Salmonella in vegetable soils without biochar. However, the content of total potassium was the main controlling factor affecting the survival dynamics of Salmonella in soils with biochar.
