摘要:向人工湿地中加入2种粒径（粒径1～2 mm和粒径<1 mm）生物炭和泥鳅，研究了不同粒径生物炭和泥鳅对湿地植物根系形态和基质硝化与反硝化强度的影响。结果表明，向人工湿地中加入泥鳅和生物炭，降低了基质的氨态氮含量，增加基质的硝态氮含量、硝化强度和反硝化强度；与粒径小(<1 mm)的生物炭相比，添加粒径大(1～2 mm)的生物炭后，湿地基质的氨态氮含量、硝态氮含量和反硝化强度分别降低了46.6%、51.1%和35.4%。加入生物炭和泥鳅均增加了湿地植物总根长和总根体积，然而与粒径小的生物炭相比，添加粒径大的生物炭后，人工湿地中植物总根长和总根体积分别降低了15.1%和6.8%。基质硝态氮含量与人工湿地中植物总根长和总根体积分别呈显著相关关系（α = 0.01）。结果表明，生物炭提高了人工湿地基质硝化强度，有利于硝态氮的生成，促进人工湿地中植物根的生长，增加了总根长和总根体积。
