The different letters indicate that significant differences were found between the treatments for each cultivar using least significant difference tests.

CK control, BC biochar, LM, lime, SC silicon-calcium fertilizer, BR brown rice rate, MR milled rice rate, HMR head milled rice rate, L/W length/width ratio, CR chalkiness rate, CD chalkiness degree, ZLY 819 Zhuliangyou 819, LLY 996 Luliangyou 996, YZX Yuzhenxiang, XWX 13 Xiangwanxian 13.

Values followed by different lowercase letters in the same group indicate significant difference among treatments n = 3, p < 0.05.
