Pantoea strain and application thereof

Abstract

The invention discloses a pantoea strain which is classified and named pantoea sp. and is preserved in China General Microbiological Culture Collection Center on July 6, 2016 with the preservation number of CGMCC No.12737. The strain can generate ammonia gas and IAA, solubilize phosphate, and increase the content of nitrogen, phosphorus and potassium in crops and rhizosphere soil thereof. The strain can be applied during growing of crops like wheat, maize and rice.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a strain of Pantoea and its application. Background technique [0002] There are many and active microorganisms in the rhizosphere of plants, which constitute the unique microbial zone of the rhizosphere. Bacteria are the main body of the rhizosphere microflora. Based on the different effects on plants, rhizobacteria can be divided into beneficial (2%-5%), harmful (8%-15%) and neutral (80%-90%). %) 3 categories. Among them, microorganisms that can promote plant growth, prevent diseases, and increase crop yields are called plant growth-promoting rhizobacteria (PGPR for short). For a long time, people's research on the biological control of soil-borne diseases has shown that rhizosphere microorganisms are ideal bio-control factors, and PGPR is not only an effective way to biologically control soil-borne diseases, but also can stimulate plant growth and increase crop produc...
