Effects of different growth patterns of Tamarix chinensis on saline-alkali soil: Implications for coastal restoration and management

Abstract

Objective: To better understand the wetland restoration, the physicochemical properties and microbial community in different compartments (rhizosphere and bulk soil) of the status of living and death T. chinensis covered soil zones were studied in a restored coastal tidal flat located on the Zhoushan island.Results: There were differences between growth conditions in the levels of soil pH, salinity, SOM, and nutrient. The living status of T. chinensis exhibited higher capacity of decreasing saline-alkali soil than the death condition of plants, and the living condition of T. chinensis showed higher uptake of N, P, and K as compared with the death samples. Proteobacteria, Bacteroidota, and Chloroflexi were the predominant bacterial communities as revealed via high-throughput sequencing. This study contributed to our understanding of halophyte growth on coastal phytoremediation, and guide theoretically for management of T. chinensis population.
