The L represents the micropore group spacing, the C represents the capillary arrangement density, the D represents the different planting seasons of tomato, the data are all average ± standard deviation in the table, the bracketed number is the factor relative contribution%, the same below. The ACE represents ACE index of soil bacterial, CHAO represents CHAO index of soil bacterial, COVERAGE represents COVERAGE index of soil bacterial, SHANNON represents SHANNON index of soil bacterial, SIMPSON represents SIMPSON index of soil bacterial, SOBS represents SOBS index of soil bacterial. Different letters in the same line meant significant difference at 0.05 level, *: P<0.05, **: P<0.01, ns: P>0.05.
