Abstract:

Changes in soil microbial communities are one of the main factors affecting continuous cropping obstacles. This study, focusing on the protected tomato (Solanum lycopersicum L.) cultivation area in Changxing County, used Illumina MiSeq technology to investigate the effects of different cropping systems—rice-tomato rotation (D treatment), continuous tomato cropping with microbial agent application (M treatment), and continuous tomato cropping (N treatment) on the rhizosphere soil microbial community. The results showed that compared with the N treatment, both D and M treatments altered the rhizosphere soil microbial community structure, but did not significantly affect microbial richness or diversity. The microbial community structures in the rhizosphere soil of tomatoes under D, M, and N treatments were similar, but significant differences existed in relative abundances at the phylum and genus levels. Differences in relative abundance at the phylum level mainly occurred between D and M treatments and between D and N treatments, whereas the bacterial community composition and abundance were relatively similar between M and N treatments. Differences in relative abundance at the genus level primarily appeared between D and M treatments, with some differences also observed between D and N treatments. Both D and M treatments significantly reduced soil organic matter, total nitrogen, and available phosphorus contents. The D treatment decreased exchangeable calcium content and increased exchangeable magnesium content, while the M treatment significantly reduced both exchangeable calcium and exchangeable magnesium contents. Soil nutrients had a greater influence on bacterial community structure than on fungal community structure. In conclusion, rice-tomato rotation is the primary factor influencing the rhizosphere soil microbial community structure in tomatoes, while microbial agent application has a certain effect on the fungal community structure. These measures contribute to alleviating soil salinization and continuous cropping obstacles in tomato cultivation.
