Study on Soil Microbial Diversity in Saline-alkali Land Around the Bohai Sea

Taking the salt farm soil and winter jujube garden soil around the Bohai Sea in Cangzhou as the research objects, and the differences on the community structure and diversity between the two soils were studied by using high-throughput sequencing technology, in order to provide reference for soil improvement and excavation of saline alkali tolerant microorganisms in the Bohai Sea.The results showed that,the bacterial diversity of winter jujube garden soil was higher than that of salt farm soil,and the fungal diversity was lower than that of salt farm soil.A total of 35phyla and 275genera of bacteria,and 7phyla and 44genera of fungi were detected in the salt farm soil.A total of 30phyla and368genera of bacteria,and 13phyla and 71genera of fungi were detected in the winter jujube garden soil.There were 7dominant bacteria phyla and 3dominant fungi phyla in salt field soil;and there were10dominant bacteria and 3 dominant fungi in the soil of winter jujube garden.Among them,Proteobacteria and Ascomycota were the largest proportion in both soils.The dominant genera in the two soils were quite different,and only GP10 was the common dominant genus.
