Abstract:
In order to investigate the influence of different nitrogenous and potassium fertilizers on soil bacterial community and soil nutrient and salt changes in tomato rhizosphere soil.Tomato was used as test object,different dosage of nitrogenous and potassium were set,with indoor pot simulation tests using high-throughput sequencing methods,the change of the soil bacterial community and soil nutrient and salt were studied.The results showed that,1)Fertilization significantly changed the dominant microorganisms,high fertilization significantly reduced the number and species of bacteria in the soil.In the dominant microorganisms Enterobacteriaceae relative abundance significantly reduced，Sphingomonadaceae and Xanthomonadaceae relative abundance slightly increased.The dominant microorganisms tended to be single.2)High fertilization significantly increased the soil conductivity (EC) and decreased the soil C/N，was the main reason for the change of the soil the dominant microorganisms.3)High fertilization significantly decreased the plant height and diameter but significantly increased SPAD.High fertilization led to the inhibition of leaf photosynthesis，resulting in a significant decline in yield.The results showed that high fertilization was the main factor leading to the secondary salinization of the soil，and the secondary salinization led to the change of the bacterial community in the soil,and the secondary salinization led to the inhibition of leaf photosynthesis，resulting in a significant decline in yield.
