*OS: original sample soil; CK: natural loam soil with tomato plant; T: soil + TOR3209 at the dose of 10⁷ CFU/g; F: soil + 10% organic fertilizer; TF: T + 10% organic fertilizer; letters a, b, c, and d in front of each treatment represent seedling stage, flowering stage, early fruit setting, and late fruit setting, respectively.

^#Different superscript small letters following each number indicate significant differences among the growth periods in the same treatment; the capital letters indicate significant differences among the treatments in the same growth stage. The comparison of OS and different treatment groups was at seedling stage.
