通过设置保留茎瘤和去除茎瘤处理，研究长喙田菁(Sesbania rostrata)在铅锌尾矿、客土和纯土环境中的生长发育情况。结果表明:保留茎瘤使长喙田菁的株高、地上部生物量、地下部生物量、全株生物量和叶绿素含量分别比去除茎瘤处理提高了2.4%～4.8%、27.4%～67.9%、28.5%～99.3%、27.6%～72.3%和17.0%～23.4%，这种作用在纯尾矿处理组最为显著，客土处理组次之，即环境愈恶劣，茎瘤这种作用愈显著，证明了茎瘤对长喙田菁适应铅锌尾矿环境有积极的贡献。
Growth of Sesbania rostrata was examined in plants treated by keeping or removing stem nodule and grown on Pb/Zn tailings or soil amended tailings or pure soil. It was shown that all the tested properties concerning the growth of S. rostrata were higher i
