Phenotypic curve-based crop growth model optimization method and system

The invention relates to a phenotypic curve-based crop growth model optimization method and system, and belongs to the field of data processing, and the method comprises the steps: carrying out the fusion of a land mode model and a single-point scale crop model, constructing a crop growth model, and achieving the continuous simulation of an area range; initializing environmental parameters of the crop growth model through a space-time clustering algorithm; outputting a crop growth simulation result through the initialized crop growth model; and performing interpolation processing on the crop growth simulation result through a Kriging algorithm. According to the method, the land surface mode model and the single-point scale crop model are fused, the crop growth model is constructed, continuous simulation of an area range can be achieved, the characteristics of the crop model are considered, direct use of spatialization data is avoided, system errors are reduced, and the crop growth model can be obtained throug
