Diversity Analysis of Rhizosphere Soil Microbial Population Structure and Screening and Identification of Dominant Salt-Tolerant Strains of Juncao"oasis no. 1"

Purpose: As a newly cultivated grass species widely used in saline-alkali soil treatment, Juncao"Oasis No.1" can effectively enhance the microbial population abundance soil. It has good effect on improving Methods: In order to further study community rhizosphere of No.1”, dominant strains with important ecological value were screened out. this paper, samples collected from planted No. 1" and unplanted 1", populations sequenced by 16SrDNA high-throughput sequencing, identify difference population, bacteria was selected, isolated cultured identified Colony PCR. Results: The results showed that Pseudomonas fluorescens Bacillus thuringiensis. No.1”. After isolation culture, PCR identification strain successfully cultured. Conclusions: Juncao" Oasis cultured, which provided theoretical basis for improvement using it is great guiding significance.
