采用多重金属Cu、Zn和Cd污染土壤进行水稻(Oryza sativa L.)盆栽试验，研究生物质炭和氮肥配施对稻田田面水中无机氮和Cu、Zn和Cd浓度的影响。结果表明，与普通氮肥处理相比，含硝化抑制剂DMPP（3,4-二甲基吡唑磷酸盐）氮肥、生物质炭+普通氮肥和生物质炭+ DMPP氮肥处理田面水中硝态氮浓度分别显著降低66.7%，33.3%和68.7%，铵态氮浓度分别显著降低66. 5%，10. 7%和67. 6%，总无机氮浓度显著降低66. 5%，14. 5%和67. 8%；Cu浓度分别降低19. 7%，0.5%和16. 2%，Zn浓度分别降低64.5%,49.9%和86.2%,Cd浓度分别降低10.0%，6.7%和13.3%。硝化抑制剂DMPP和生物质炭均可有效降低稻田氮素，Cu、Zn和Cd流...

In a rice cultivation pot experiment, the influences of combined application of biochar and nitrogen fertilizers on concentrations of inorganic nitrogen and Cu, Zn and Cd in surface water of paddy soils contaminated with heavy metals Cu, Zn and Cd were studied. Results showed that, compared with the treatment of common nitrogen fertilizer, nitrate, ammonium, total inorganic nitrogen, Cu, Zn, and Cd concentrations of treatment of common nitrogen fertilizer with nitrification inhibitor 3, 4-dimethylprazole phosphate（DMPP）, treatment of common n...
