Dynamic model of crop growth system and numerical simulation of crop growth process under the multi-environment external force action (Q1888918)

According to biomechanical theory and methods the dynamical mechanism of crop growth under external force actions of multi-environment factors (light, temperature, soil, nutrients, etc.) was comprehensively explored. A continuous-time Markov (CTM) approach was adopted to build a dynamic model of the crop growth system and a simulated numerical method. The growth rate responses to the variation of the external forces and the change of biomass saturation value were studied. The crop growth in a semiarid area was taken as an example to carry out a numerical simulation analysis, the results providing a quantitative basis for field management. Comparing the dynamic model with other plant growth models, the superiority of the former is that it displays the multi-dimensionally of resource utilization by means of combining macroscopic with microcosmic processes of resource transitions. A simulation method of crop growth systems is advanced and manipulated. A real simulation result compares well with field observational results.
