Abstract

The invention discloses a method and a system for establishing a dynamic growth model of a crop canopy structure, and a storable medium, and relates to the technical field of plant growth analysis. According to the method, crop canopy structure characteristics and a change rule between crop development processes are explored, a crop canopy three-dimensional structure model is established, and corn dynamic growth simulation is constructed through fusion. In the model, a growth day is adopted to describe a crop growth and development stage, a Logistic equation is adopted to perform dynamic simulation of a corn canopy two-dimensional structure, a spatial topological structure is adopted to perform representation of leaf veins, leaf edges and the like, and on the basis, a dynamic simulation method of a crop canopy three-dimensional spatial structure is finally created. The coupling simulation of the hydrothermal carbon multi-process in a complex farmland ecosystem is realized, and the simulation capability and the universality of a crop model are effectively improved.

Description

technical field [0001] The invention relates to the technical field of plant growth analysis, and more specifically relates to a method, a system and a storage medium for establishing a dynamic growth model of a crop canopy structure. Background technique [0002] By describing the characteristics of each component in the farmland ecosystem and its impact on the system, the crop model quantitatively depicts the complex relationship between meteorological factors, soil moisture, nutrients, temperature and other elements in the crop ecosystem in many processes such as crop growth and development. The interaction relationship provides an important means for optimizing cultivation, reasonable water supply, rational utilization of resources and optimization of planting benefits. In recent years, with the development of computer technology and the continuous improvement of computer performance, scholars at home and abroad have made great progress in the research and application of...
