试验通过平板划线法从其根际分离纯化出6株细菌，并对菌株进行形态特征观察

In the experiment, 6 strains of bacteria were isolated and purified from the rhizosphere by plate streak method, and the morphological characteristics of the strains were observed, and a series of physiological and biochemical tests such as Gram staining were carried out. Quinoa was used to detect the growth-promoting function of each strain, and the 16S rRNA molecular identification and gene drafting of a strain with excellent growth-promoting effect were carried out.

Six strains of bacteria were isolated and purified from their rhizosphere by plate scribing method, and a series of physiological and biochemical tests such as morphological characteristics observation and Gram staining were carried out. Quinoa was used to detect the growth promoting function of each strain, and a strain with excellent growth promoting effect was identified by 16S rRNA molecule and gene sketch.
