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 RL represents the total root length, the RS represents the total root surface area, the RV represents the total root volume, the RT represents the total number of root tips, the RB represents the total root bifurcation number, the RA represents the root activity. Different letters in the same line meant significant difference at 0.05 level, *: P<0.05, **: P<0.01, ns: P>0.05.
