Livestock and poultry manure containing high levels of copper and zinc have led to contamination of farmland and products which could have an impact on human health. Biochar is an inexpensive and efficient heavy metal absorbent. In the present study, we have used biochar to mitigate the effects of heavy metals on the growth of wheat seedlings. The study showed that the effects of heavy metals on wheat seedlings growth were mitigated by increasing exposure to biochar. Compared to the control group, the germination potential, germination rate, germination index and vigor index of wheat seedlings with supplemented biochar increased significantly. Moreover, the specific activity of catalase, peroxidase, superoxide dismutase decreased and chlorophyll contents increased, which promote wheat growth and suggests that the addition of biochar could reduce the effects of heavy metals on wheat seedlings.
家畜和家禽粪便含有高水平的铜和锌，导致农田和农产品受到污染，可能对人类健康产生影响。生物炭是一种廉价且高效的重金属吸附剂。在本研究中，我们使用生物炭来减轻重金属对小麦幼苗生长的影响。研究表明，通过增加生物炭的暴露，重金属对小麦幼苗生长的影响得到了缓解。与对照组相比，添加生物炭的小麦幼苗的发芽势、发芽率、发芽指数和活力指数显著增加。此外，过氧化氢酶、过氧化物酶、超氧化物歧化酶的比活降低，叶绿素含量增加，促进了小麦的生长，表明添加生物炭可以降低重金属对小麦幼苗的影响。
