摘要：A pot experiment was conducted to study the effects of biochar on physiological characteristics and accumulation of Cd and Pb of Lonicera japonica in Cd and Pb contaminated *** results showed that adding 2%~16%biochar could significantly increase the net photosynthetic rate,chlorophyll content and root activity of Lonicera japonica,and significantly reduce its SOD *** 6%~16%biochar was added,the contents of Cd and Pb in roots and stems of Lonicera japonica decreased significantly;when 2%~16%biochar was added,the contents of Cd and Pb in the leaves and flowers of Lonicera japonica decreased *** more than 8%biochar can reduce the content of Cd and Pb in Lonicera japonica to a safe range level.
