Note:
Different letters in the same row within the same rice means the significant differences in P < 0.05. * indicate significant correlations at the 0.05 levels. TD, tillage depth; TD14, tillage depth 14 cm; TD17, tillage depth 17 cm; TD20, tillage depth 20 cm; TD 23, tillage depth 23 cm; Y, year.
