[Mycorrhizal research on nitrogen-fixing plants].

Advances in mycorrhizal research on nitrogen-fixing plants were introduced. The universality of mycorrhizal formation in nitrogen fixing plants, the reciprocal promotion effect of symbiosis, and the application prospect of mycorrhizal techniques under stressed conditions were summarized and reviewed. The mechanism of enhancing nitrogen fixation of N-fixing plants by mycorrhizal fungi in symbiosis was preliminary discussed.
