摘要

印度卢迪亚纳旁遮普农业大学的一项盆栽实验评估了稻米渣生物炭对土壤中铅和镉的修复作用以及对印度芥菜生长的影响。土壤中添加了镉（0、10、25 毫克/千克-¹）和铅（0、25、50 毫克/千克-¹），并用生物炭（0、0.5、1、2% w/w）进行改良，采用完全随机设计，三次重复。添加 2% 的生物炭后，土壤中的 DTPA-Pb 和芽中的 Pb 分别减少了 61% 和 56%。添加 1%的生物炭时，干物质产量（DMY）增加了 18%，而添加 2%时则减少了 19%。1% 的生物炭可使芽中的铁、锰、锌和铜分别增加 11.39%、26.74%、5.89% 和 17.72%。通过减少共污染土壤中的铅污染，米渣生物炭明显改善了印度芥菜的 DMY 和微量营养元素含量。

Effect of Rice Residue Biochar on Lead Remediation, Growth, and Micronutrient Uptake in Indian Mustard (Brassica juncea (L.) Czern.) Cultivated in Contaminated Soil.

A pot experiment at Punjab Agricultural University, Ludhiana, India, assessed rice residue biochar's effect on remediating lead and cadmium in soil and on Indian mustard growth. Soil spiked with Cd (0, 10, 25 mg kg⁻¹) and Pb (0, 25, 50 mg kg⁻¹) was amended with biochar (0, 0.5, 1, 2% w/w) in a completely randomized design with three replications. Adding 2% biochar reduced DTPA-Pb in soil and Pb in shoots by 61% and 56%, respectively. Biochar increased dry matter yield (DMY) by 18% at 1% but decreased by 19% at 2%. The 1% biochar increased shoot Fe, Mn, Zn, and Cu by 11.39%, 26.74%, 5.89%, and 17.72%, respectively. Rice residue biochar significantly improved the DMY and micronutrient content of Indian mustard by reducing lead contamination in co-contaminated soil.
