Zusammenfassung: | The invention relates to the technical field of biology, in particular to application of paenibacillus polymyxa YF in promoting plant growth, the paenibacillus polymyxa YF is preserved in the China General Microbiological Culture Collection Center on December 21, 2020, the preservation number is CGMCC No.21517, and the paenibacillus polymyxa YF is preserved in the China General Microbiological Culture Collection Center on December 21, 2020. The amount of indoleacetic acid (IAA) secreted by the paenibacillus polymyxa YF in the culture medium containing the Trp is 13.83 mg/L; iron carriers can be secreted; green fluorescence is successfully expressed and can be detected on the surfaces and the interiors of roots and stems, the average colonization rate is 10 < 4 > CFU/g, and the duration time is long. Various physiological indexes of potatoes treated by 108 CFU/mL of the paenibacillus polymyxa YF are improved compared with those of potatoes treated by contrast treatment, which shows that the paenibacillus polym |
