    As the world's population grows, pursuing sustainable agricultural production techniques to increase crop yields is critical to ensuring global food security.Agricultural biotechnology has brought revolutionary changes to agriculture and is of great significance in promoting the sustainable development of agriculture. This study aimed to investigate the role of JZ (compound microbial agent) and MZ (biological agent made from plant materials) in improving the rhizosphere microecological environment and nutrient availability for rice. This study found that JZ enriched Cyanobacteria with biological nitrogen fixation functions; spraying MZ can enrich some beneficial microbiota, such as Bradyrhizobium, playing a role in symbiotic nitrogen fixation. Meanwhile, JZ and MZ were found to affect rhizosphere soil metabolism and improve potassium and nitrogen availability. In addition, JZ played a role in promoting the degradation or transformation of fungicides in the rhizosphere soil environment. Overall, applying agricultural biotechnology through optimizing rhizosphere microecology to improve rice yield showed great potential.
