A pot experiment was conducted to study the effects of different biochar types [addition of rape straw biochar (RB), addition of paddy straw biochar (PB), addition of wheat straw biochar (WB) and addition of corn straw biochar (MB)] on the absorption of Ca, Mg and B in peach seedlings. The result showed that compared to the control, all treatments added with biochar significantly decreased the Ca content in roots in peach seedlings. The Ca content in stems and leaves under the treatment of RB and PB in peach seedlings was higher than the control. The Mg content in roots and stems under the treatment of PB in peach seedlings was higher than the control. The Mg content in leaves in peach seedlings of all treatments added with biochar was lower than the control. The B content in roots, stems and leaves under the treatment of PB, WB and MB in peach seedlings was higher than the control and the B content under the treatment of PB was at a higher level. Therefore, the treatment of PB was beneficial to the absorption of trace elements in peach seedlings.
