| 摘 要： | 该文主要研究了花生壳生物炭对生菜镉吸收和土壤pH的影响,结果表明:花生壳基生物炭随着用量的增加,可使生菜产量增加9.7%~46.2%;生菜对Cd的吸收降低8.4%~38.4%;土壤有效态Cd的含量降低7.0%~23.7%;土壤pH值提高0.09~0.67个单位;花生壳基生物炭随着炭化温度由300℃提高到700℃,对降低生菜吸收Cd和提高土壤pH效果更显著,降低生菜地上部Cd含量21.8%~32.7%;降低生菜根系Cd含量17.0%~30.9%;提升土壤pH值0.49~0.94个单位。

| Abstract: | Effects of peanut husk biochar on absorption of Cd in lettuce and soil pH were studied. The results showed that lettuce production increased by 9.7%~46.2%with the increase of the amount of peanut husk biochar,the absorp?tion of Cd in lettuce reduced by 8.4%~38.4%,the content of available Cd in soil reduced by 7.0%~23.7%,soil pH increased by 0.09~0.67 units. The effects of reducing the absorption of Cd and improving the pH in the soil is more significant with the carbonization temperature from 300℃to 700℃,the absorption of Cd in the upper of lettuce re?duced by 21.8%~32.7%and in root of lettuce reduced by 17.0%~30.9%,and soil pH increased by 0.49~0.94. |
