| 摘 要： | 以玉米为试验材料，采用盆栽方法模拟土壤Cd污染状况，分别将丛枝菌根真菌Glomus diaphanum和Glomus mosseae接种于镉污染土壤中，研究两种菌根真菌对玉米生长及对Cd吸收、分配的影响．结果表明：与未接种的对照相比，接种Glomus diaphanum菌根使玉米的生物量增加了5．79倍，地上部镉含量降低了53．9％，地上部磷含量增加了4．6倍．菌丝侵染使植物将镉滞留在根部，抑制了镉向地上部的转移．其中，接种Glomus diaphanum菌显著于接种Glomus mosseae菌．因此，在镉污染土壤原位修复中，接种Glomus diaphanum菌有助于抑制重金属迁移．

| Abstract: | The maize was inoculated with two arbuscular mycorrhizal fungi(AMF) Glomus mosseae(Glm) and Glomus diaphanum(Gld) in the cadmium-contaminated soil. A pot culture experiment was carried out to study the effect of AMF on the growth and cadmium uptake and translocation of maize.The results show that the inoculating Gld makes the biomass and phosphorus content of maize increased by 5.79 times and 4.6 times,respectively,and the content of cadmium in shoot decreased by 53.9% compared with those of non-mycorrhizal ones.Infection of mycelium makes the excessive heavy metal keep in the root of plants,and suppresses the transformation of heavy metal to shoot.Inoculating Gld could get significant results than inoculating Glm.Therefore,inoculating Gld could restrain the translocation of heavy metal in remediation of cadmium-contaminated soil on site. |
