Agricultural arsenic (As, CAS. No. 7440-38-2) over the issue of pollution has been related to people’s livelihood, security and moderate use of As contaminated soil is an important aspect of contaminated soil remediation. In this potted plant experiment, synergistic effects of arbuscular mycorrhizal fungi (AMF) Funneliformis mosseae and iron (Fe, CAS. No. 7439-89-6) oxides on plant growth and phosphorus (P, CAS. No. 7723-14-0), As and Fe uptake by maize (Zea mays L.) were studied on simulating medium As-polluted soils in greenhouse. Different amounts (0, 5, 10, 20, 40 g kg^− 1) of iron tailings (IT) were added. The results showed that IT20 and IT40 addition significantly increased mycorrhizal infection rate, plant biomass, root length and P, Fe uptake under FM treatment; IT40 addition decreased As concentration in roots. In addition, FM inoculation increased biomass, root length and P uptake by shoots, but decreased Fe and As concentration in shoots. Therefore, the combined FM inoculation and IT40 addition promoted maize growth and decreased As concentration in shoots by decreasing As absorption efficiency, increasing P and Fe uptake and P/As ratio.

农业砷（As, CAS. No. 7440-38-2）的污染问题一直关系到民生、安全和适度利用砷污染土壤是污染土壤修复的一个重要方面。在这个盆栽植物实验中，丛枝菌根真菌 (AMF) Funneliformis mosseae和铁 (Fe, CAS. No. 7439-89-6) 氧化物对植物生长和磷 (P, CAS. No. 7723-14-0)的协同作用), 玉米 ( Zea mays L.) 对砷和铁的吸收在模拟温室中砷污染的土壤中进行了研究。不同的量（0, 5, 10, 20, 40 g kg ^{- 1}) 添加铁尾矿 (IT)。结果表明，在FM处理下，IT20和IT40的添加显着提高了菌根侵染率、植物生物量、根长和P、Fe的吸收；IT40 添加量降低了根中的 As 浓度。此外，FM 接种增加了枝条的生物量、根长和 P 吸收，但降低了枝条中的 Fe 和 As 浓度。因此，FM 接种和 IT40 的联合添加通过降低 As 吸收效率、增加 P 和 Fe 吸收以及 P/As 比来促进玉米生长并降低地上部的 As 浓度。
