Biochar Combined with PGPB Alleviates Salt Stress in Cotton by Improving the Rhizosphere Microbial Community and Regulating Metabolic Characteristics
The salinization of agricultural land is a growing global concern. Salt-tolerant plant growth-promoting bacteria (PGPB) and biochar have been shown to enhance crop yields and improve soil quality. However, the coupling of biochar with PGPB has not been widely studied. In this study, a composite coupling agent was prepared using Sutcliffiella horikoshii, Bacillus sp. 13BM45Y12, Alkalihalobacillus alcalophilus, and biochar, and was applied in a pot experiment to elucidate its ameliorative effects on cotton under salt stress
