摘要
菌根真菌与陆地上80%以上的植物形成菌根共生体,提高宿主对资源的竞争力,影响植物的生长发育,在生态系统碳(C)、氮(N)、磷(P)循环过程中扮演着极为重要的角色。菌根与植物之间的营养交换是公平的,菌根真菌通过把从土壤中吸收的氮、磷元素交换给植物,从而获得植物光合产物碳,并将植物光合产物碳输送到根际甚至根际外土壤中。菌根共生体形成的错综复杂的菌丝网络连接了同种或不同种的植物个体,促进了植物间的地下交流。本文重点分析了菌根真菌在森林碳氮磷循环方面的国内外研究进展,以及目前存在的问题和未来的研究重点。
Mycorrhizal fungi can form arbuscular mycorrhizae with more than 80% species of trees in the forest,thus improves the host’s competitiveness for resources.It plays an important role in the cycle process of carbon(C),nitrogen(N),and phosphorus(P),in the forest ecosystem.The exchange of nutrients between mycorrhizal fungi and plant is fair.Mycorrhizal fungi exchange nitrogen and phosphorus from the soil to plants to obtain plant photosynthetic carbon and transport plant photosynthetic carbon to the rhizosphere and even to the soil beyond the rhizosphere.Mycorrhizal symbionts form an intricate network of mycelium that connects individual plants of the same or different species,facilitating underground communication between plants.Advances of recent mycorrhizal researches in the cycle process of carbon nitrogen,phosphorus and nitrogen were summarized and related fields in future studies were also mentioned in this review paper.
