[Objective] According to the high-efficiency phosphorus-dissolving fungi from the rhizosphere soil of Allium mongolicum Regel, the phosphorus-dissolving characteristics, salt-tolerant ability and the promoting effect on Mongolian alfalfa were determined, which provided excellent bacterial resources for the development of phosphorus-dissolving microbial fertilizer. [Methods] The fungi with certain phosphorus solubilizing ability were screened by Mengjinna organic phosphorus and medium. The morphological characteristics and ITS rDNA sequence analysis were used to identify. The ability of different strains to utilize inorganic phosphorus source, salt and alkali resistance and the promoting effect on Allium mongolicum Regel.
