The invention discloses enterobacter ludwigii PN6 and application thereof. The classification name of the strain is Enterobacter ludwigii with a strain number of PN6, the strain is collected in the China Center for Type Culture Collection and has a collection number of CCTCC NO: M 2019881. The strain PN6 screened from a Phyllostachys edulis root system has an obvious anti-bacteria function for a pathogenic bacterium, i.e., C .phyllostachydis, of the shoot blight of Phyllostachys edulis, a fermentation liquor inhibition rate of the strain PN6 can be 49.28%, and in addition, the strain PN6 has acapacity of efficiently dissolving phosphorus and secreting IAA (indole-3-acetic acid). The strain PN6 disclosed by the invention has an acceleration function for the growth of Phyllostachys edulis,an experiment data displays that a liquid fungicide prepared from the PN6 has an obvious growth promotion function for growth indexes, including the ground diameter, the seedling height, the chlorophyll and the like of the Phyllostachys edulis, in addition, the stress resistance of the Phyllostachys edulis can be increased, and an occurrence probability of the shoot blight of Phyllostachys edulisis reduced. Therefore, the invention provides an excellent strain resource for developing an environmentally-friendly special biofertilizer for the Phyllostachys edulis.

The invention discloses salinicola zeshunii JP11 with salt-tolerant and growth-promoting functions. The strain is deposited in China General Microbiological Culture Collection Center on September 14, 2021 and has the deposit number of CGMCC No.23407. The invention also discloses use of the salinicola zeshunii in relieving an inhibition effect of salt stress on rice growth and a liquid culture medium suitable for fermentation by the strain. Experiments confirm that the salinicola zeshunii JP11 has various growth promoting characteristics such as dissolving potassium and dissolving and solubilizing phosphorus, high salt tolerance and a wide salt tolerance spectrum. A bacterial solution prepared by using the JP11 can improve salt tolerance and growth promoting of rice, accelerates a seedling growth and increases biomass under salt stress, and thus promotes rice germination and seedling growth. Meanwhile, the provided JP11 can increase the content of soluble potassium in the soil to 25.4% and the content of soluble phosphorus in the soil to 45.9%, thus effectively improves a utilization rate of the soil and provides an excellent strain resource for saline-alkali farmland soil remediation.
