PendingCN122511395ACalculable healthhealth measurable
This invention discloses a method and system for selecting optimal crop rotation based on multi-omics networks, belonging to the field of smart agriculture technology. This invention solves the problems of traditional crop rotation assessment relying on discrete fertility indicators, resulting in lag and false negatives. Its core is to integrate multi-omics data on soil metagenomics, metabolomics, and physicochemical properties. After feature identifier standardization and hierarchical balanced feature selection, an ecological collaborative network including biotic and abiotic components is constructed. Modularity index and average path length are extracted as network topological fingerprints. Simultaneously, inter-group statistical tests are performed on soil physicochemical properties, and Cohen's d effect size is calculated. Finally, the optimal crop rotation pattern is determined through a dual evidence chain of superior network structure and a large fertility improvement effect size. This invention achieves a reliable correlation from soil micro-ecological state to macro-fertility phenotype, providing a standardized and repeatable intelligent screening process that can be widely applied to crop rotation scheme decision-making for sustainable farmland production.
