Screening of bacteria that promote straw decomposition and their application in straw returning to the field
Straw returning to the field is a conservation tillage technology that has been widely applied in the development of sustainable agriculture. However, the low-temperature and arid environment in northern regions results in low straw decomposition efficiency. In this study, a decomposition-promoting Bacillus strain was isolated, its stress resistance was evaluated, its whole genome was analyzed, and field experiments were conducted to explore its effects on straw decomposition, soil physicochemical properties, soil microbial composition, and other aspects.
