Embodiment Construction

[0020] The present invention obtains a bacterial strain with strong salt-tolerant and life-promoting activity through the isolation of actinomycetes in the rhizosphere soil of the coastal zone and the screening of salt-tolerant and growth-promoting characteristics, and the serial number is RS019. Its taxonomic status was confirmed by morphological characteristics, physiological and biochemical, 16S rRNA gene sequencing and phylogenetic analysis. Through plate seed germination and pot experiment verification, adopt the actinomycete Micromonospora aurantiaca RS019 provided by the invention, have the ability to promote wheat seed germination and seedling growth under salt stress, significantly improve the adaptability under its salt stress, the The method can be fermented and used as bacterial fertilizer to improve the salt-tolerant ability of wheat and promote the planting of wheat in saline-alkali land.

[0021] The isolated strain is Micromonospora aurantiacus, code-named RS01...

Abstract

The invention discloses an actinomycete Micromonospora aurantiaca, which is characterized in that the strain belongs to the actinomycete Micromonospora aurantiaca (Micromonospora aurantiaca), code-named RS019, and was preserved in Guangdong on May 5, 2017 Provincial Microbial Culture Collection Center, the preservation number is GDMCC 60177. Micromonospora aurantiacus RS019 isolated and screened by the present invention has multiple growth-promoting characteristics such as nitrogen fixation, production of plant growth hormone indole acetic acid (IAA) and ammonia production, and can tolerate 5% NaCl. Under the condition of 100mM NaCl concentration, the wheat seed germination rate can be significantly improved after the treatment of the wheat, and the wheat seedlings can be re-grafted with the bacterial suspension, which can significantly slow down the symptoms of salt damage and increase the biomass to promote the growth of wheat under salt stress. Helps improve the salt tolerance of plants and reduce the use of chemical fertilizers.

Description

technical field [0001] The invention belongs to the research field of microbial fertilizer and crop adversity protection, and relates to a micromonospora actinomycete and its application. Background technique [0002] Soil salinization is one of the main abiotic stress factors threatening global agricultural production and crop yield. Currently, nearly 50% of the irrigated land in the world is threatened by salt stress to varying degrees. According to statistics, the area of ​​saline-alkali soil in the world accounts for about 7% of the total land area, and it has a tendency to increase year by year. The salinized soil area in my country is about 1.0×10 8 hm 2 , accounting for about 37% of the total land area. Soil salinization not only affects plant metabolism and photosynthesis, but also reduces plant intake of soil nutrients and trace elements. Previous studies have shown that NaCl is the most important component of salinized soil. Under its stress, plants will experi...
