Abstract

The invention discloses achromobacter marplatensis TNSC2011with a preservation number of CGMCC (China General Microbiological Culture Collection) No.8192 and an application thereof in sugar beet cultivation. Taxonomic status of the obtained bacterial strain is primarily determined by carrying out determination and phylogenetic analysis of morphological characteristics, physiological-biochemical characteristics and a 16 SrDNA sequence on the obtained bacterial strain; meanwhile, characteristics such as bacteriostasis rate, growth promotion and stability of fermentation liquor of the bacterium TNSC2011 are deeply researched, so that crop growth can be effectively promoted; slightly-soluble phosphate can be converted into soluble phosphate which can be biologically utilized, so that photosynthesis is improved, and the achromobacter marplatensis is proved to be an excellent endophyte with the serial number of TNSC2011; the endophyte is applied on sugar beet cultivation to obtain a good effect, so that technical effect is outstanding and application value is wide.

Description

technical field

[0001] The invention relates to the technical field of application of agricultural microorganisms, in particular to the technical field of endophytic growth-promoting bacteria of sugar beet and its application. Background technique

[0002] Endophytes generally exist in plants, form a harmonious symbiont with the host, and produce a large number of secondary metabolic active substances. It is reported that endophytes can enhance the host's disease resistance, improve plant productivity, stress and insect resistance, and have herbicide activity and other characteristics. Therefore, endophytes can be used as potential factors in biological growth promotion, and have important uses in the development of ecological agriculture and biopesticides. plant endophytic bacteria ( Endophytic bactena ) can promote the growth of its host plants through different pathways, and its role is similar to that of plant rhizosphere bacteria ( PGPR ), plant growth-promoting bac...
