Diversity of Soil Microbial Communities under Different Soil Salinity Levels Analyzing by PLFA

摘要

Under different levels of soil salinity, diversity of soil microbial communities from Hetao irrigated land of Inner Mongolia was studied by phospholipid fatty acid (PLFA) analysis. The study found that PLFAs biomass in saline soil was significantly lower than those of strongly salinized soil and slight salinized soil. Microbes was bacteria-based from these soil. The bacterial PLFA loading in saline soil is significantly less than those of strongly salinized soil and slight salinized soil . The results cluster analysis showed that changes had obviously taken place on soil microbial composition and quantity under different levels of soil salinity.
