In this study, we collected soybean inter-root soil (clay soil) from the cold region of Heilongjiang Province, China, screening for cold-tolerant phosphorus- and potassium-solubilizing bacteria by gradient-cooling-directed design mixed bacterial agents. This study screened phosphorus-solubilizing constructed We analyzed strain’s phosphorus/potassium solubilizing capacity, as well its organic acid secretion ability, to reveal mechanism detoxification phosphorus potassium.

This article presents a systematic review of the ecophysiological mechanisms underpinning essential role plant-growth-promoting microorganisms (PGPMs) in improving rice yield and quality. The scientific literature is thoroughly reviewed, highlighting how PGPMs positively influence growth, development, health plants. Key aspects, such as nitrogen fixation, nutrient solubilization, hormone production, disease resistance induction, are emphasized. Additionally, technological advancements related to PGPM use analyzed, including identification effective strains, formulation enhanced biofertilizers, genetic engineering. concludes that represent promising tool with which boost sustainability productivity cultivation, providing robust foundation for future research practical applications field crucial global food security.
