Fritillaria taipaiensis P. Y. Li is a plant used to treat respiratory diseases such as pneumonia, bronchitis, and influenza. Its wild resources have become increasingly scarce, the demand for efficient artificial cultivation has increased significantly in recent years. Phosphorus-solubilizing fungi can promote dissolution of insoluble phosphate complex, which benefits nutrition. Another strategy efficiently cultivating traditional Chinese medicine plants combine soil with phosphorus-solubilizing provide nutrients other desired features. This study aimed investigate effects different their combinations on photosynthesis, physiological biochemical characteristics, expression protective enzyme system-related genes, find reference strain suitable industrial development F. Li. In this study, isolated from rhizosphere were applied first time. seven treatment groups (S1-S7) one control group set up using indoor pots follows: S1 (inoculation Aspergillus tubingensis), S2 A. niger), S3 nigerfunigatus) S4 tubingensis S5 nigerfunigatus), S6 niger S7 tubingensis, niger, CK (control group). These strains inoculated into containing bulbs,and photosynthetic basic indicators, differential gene systems leaves determined. Most growth indexes showed significant differences fungal compared (P < 0.05). The stem diameter height highest, 58.23% 62.49% higher than those group, respectively. leaf area was largest, by 141.34% that group.
