Effects of Arbuscular mycorrhizal fungi on absorption of nitrogen and phosphorous in aquatic plants
摘要
Abstract
Arbuscular mycorrhizal ( AM) fungi are a class of microorganisms, capable of symbiosis with most terrestrial plants and improving plant growth and adsorption of nitrogen and phosphorus. Wetland plants play a decisive role in the purification process of wetland pollution, but there are few reports on improving the absorption capacity of nitrogen and phosphorus of wet plants by AM fungi. In this study, three kinds of wetland plants were selected, such as Lythrumsalicaria, Cyperusalternifolius and Iris wilsonii. In the pot culture, they were inoculated with Rhizophagusintruradices ( RE ) , Glomusmosseae ( GM ) and Claroideoglomusetunicatum ( CE ) fungi, aboveground, underground and whole plant biomass and nitrogen and phosphorus uptake of different plant species were compared with CK. The results showed that the effects of AM fungi on plant growth and adsorption of nitrogen and phosphorus were different between and inside plants, and the promotion and inhibition effects were also different. The best combinations of AM fungi and plant were: Lythrumsalicaria-RE, Cyperusalternifolius-RE, Iris wilsonii-GM. The plant biomass, TN and TP of the three plants were increased by 17 . 7% ~29 . 8%, 15 . 7% ~39 . 0% and 22 . 3% ~62 . 6%, respectively after inoculated with the best AM fungi. This study provided a new alternative for enhancing nitrogen and phosphorus uptake capacity of wetland plants in the future.关键词
